Reddit mentions: The best 3d printer platforms

Best thing to do is get some Mirror Tiles at any Home Improvement store. Cheap and flat (who wants a wavy mirror? LOL).

Lowes in the US has them $9 for Six. I had two not flat but 4 fine. Home Depot and Ace Hardware also have them IKEA is another source.

>Athorbot adhesive mats - Those are a knockoff clone of the BuildTak mats. They're OK, but do wear out.

I went down that road last year, ended up using PEI on my printers and haven't looked back:

https://smile.amazon.com/gp/product/B074XLD5QH

Sticks well when warm or hot, releases almost instantly when cool.

But BEFORE any of this works your Bed needs to be flat,most machines it's NOT. (Not the glass, the Aluminium bed).

A quick check with a known straight edge (like a 24" machinist's rule) will let you see. Put it edge on with a well lit white wall or sheet of paper and check the bed, front to rear, also side to side.

Most have a dip in the center, some are raised in the center.

Unless the glass is VERY thick, it will dip when clipped to the bed.

I did a couple posts / comments about how to properly flatten the bed. It's a bit of work, but you'll do your happy dance when it's nice & flat.

Most adhesion & first layer issues are caused by an unflat and un-trammed (proper name for "leveled") bed. Probably 50-60% of the "Help Me!" posts are this!

With a properly trammed bed you don't need glue or Hairspray, or tape or other "goop" in 90% of the cases. You can actually print straight onto the glass or PEI, many do. (including MOI) Super smooth bottoms.

Here's' the posts, first, some basics:

Then follow this to tram the bed:

Let us know how it goes!! Trust me, it's worth the effort.

I absolutely must recommend a PEI sheet for printing ABS. It's the best printing surface I've used for being able to print ABS without having issues with the print tending to pull off the surface. I was using glass which is great for PLA, but even with hairspray, I was having issues with small areas of ABS pulling up somewhat regularly. Because it's a stiff sheet, it's easier to apply than tape without worrying about air bubbles. I still recommend having a boro glass plate as it's good for ensuring your bed is perfectly flat. Links below.

Also, just FYI, if you plan on printing any part upgrades for your printer, especially if you plan on using cable chains, keep in mind that ABS prints pretty much require the use of an enclosure to keep the temperature stable and warm. PLA has a tendency of deforming when even only slightly warm and I had a number of issues when I first started using a cabinet as a result. You'll want to print your part upgrades in ABS so as to maintain rigidity in a warm enclosure. You can always start with PLA and later upgrade the parts to ABS, but keep this in mind if/when you move to filaments that require a warmer print environment.

And above all, upgrade your firmware to ensure you have some minimum safety features. I nearly had a fire early on with mine when my hotend thermal probe was accidentally pulled out during a print causing it to have a thermal runaway.

Not so much optimization but you'll find that every 3D printer is going to have self printed customization added to it. Things like spool holders and tool boxes. You'll find things like that for both models on Thingiverse but you'll find more for the Ender3 than you will for the Mega.

I don't own an Ender3 and I am happy with my Mega, but if I were in your shoes I'd go with the Ender. From all accounts it's a great printer that will require a little more setup but /r/ender3 is an active subreddit who can provide assistance when you get going and it's currently going for an amazing price at Woot today only.

Edit: If you do go with the Ender I would suggest you also pick something like this up. From what I'm reading it's just like the Ultrabase for the Mega and makes removing prints a dream. Honestly you just let it cool down and the prints can just be picked up. You end up saving filament because you don't have to create rafts and such.

Edit: Success! Increased bed heat to 60c and used the famous gluestick. That resolved to lack of adhesion for me and got me a good benchy. now, there are other issues to resolve still - but isn't that half the adventure with this hobby? Thanks for all the help everyone!

​

Looking for some guidance on the right steps to troubleshoot and hopefully resolve my new issues.

​

TL:DR: Installed new glass build plate and PLA prints will not stick. No successful prints over 30 minutes yet. I've had one print completely detach, and this benchy had significant warping. The issue wasn't present with the buildTak - but the buildTak had insane adhesion - too much actually.

​

Setup:

Monoprice Select Mini v2. Almost all stock, this is the first build related upgrade. PLA, 50c bed temp, 200c hotend temp, 0.175 layer height, 20% infill, 50mm print speed.

​

Long Version:

I had been using the buildtak for a few months and had two problems: too much adhesion (breaking prints while removing from buildtak) and the bed was bowing up in the middle.

​

I bought this borosilicate glass plate and a silicone thermal pad to make sure it would heat up. Installed them, z spacer, attach with 4 binder clips, leveled the bed. Tried using it without any other changes and PLA would not stick at all. Then tried to use some hairspray and it appeared to work after a little fiddling. Finally got what I thought was a good first and second layer. Checked on it about every 10 minutes and suddenly I noticed that it's about half off the glass surface with warping. I was pretty sure it was going to detach completely soon, so I just stopped the print.

​

Anyone have suggestions on how to properly use glass or some tricks? I was previously using tricks to get less adhesion so this is a bit new - and I'd prefer to keep the glass as flat/smooth as possible (wouldn't prefer to sand it for example).

​

I've tried heating the bed to 60c and letting it pre-heat for longer to let the glass heat up and that seemed to help, but not completely. I've also tried to slow down the first layer and that seemed to help the first layer adhesion a bit - I haven't re-tried a benchy with a slower 1st layer yet, but I wasn't confident that helped the adhesion enough to prevent the warping.

​

I printed a bed level test and so long as the PLA stuck, it looks pretty good - although my center is higher than the edges even though all 4 corners look OK - but that's an issue for another day and another thread.

Getting glass to stick well can be a pain. You need to either use glue sticks or hair spray. Sometimes you don't need either of those things, but you'll definitely need to clean it with isopropyl alcohol to keep the surface very clean. A dirty surface will not stick with glass.

On top of the glass I use the build sheet from
https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F223085797482

And then I use the build sticker from
https://www.amazon.com/dp/B07DC7NG4N/ref=cm_sw_r_cp_apa_i_0teECbR4G25EP

For a rigid yet flexible removable top build surface.
If you put the build sticker directly on the glass, it'll be extremely hard to remove relatively flat prints which is why I opt to have a more flexible and removable surface on top of the glass.

I use the petsfang which helps get better layers and overhangs. A good upgrade for print quality overall. "Boogers" are usually a sign of over extrusion. Printing colder may help or even reducing the flow rate might help. An upgraded part cooler may help as well.

Regarding the computer, I've been there. I'm sorry to hear that.
Hopefully you can get your station up and running a good slicer soon.

Now about the bed... I'm assuming your using PLA, but I could be wrong.
What thermoplastic are you printing with?

If it is PLA, have you tried using rubbing alcohol to clean the bed surface?
Old prints can leave a thin layer of more plastic, dirt, dust, debris etc.
Giving it a good wipe down between prints might help too.
The picture you provided also shows the standard Ender 3 bed. Is your bed surface removable?
Meaning did it come with the alligator clips holding down the bed to the aluminum?

Or is it removable?

I had to replace my bed surface because it kept peeling up.
I ended up buying this CCTREE bed surface and bonding that to a spring steel sheet I got from Amazon.
Not only did this dramatically help my bed adhere to ABS ( which is almost too good now ) it also has the benefit of flexing easily and having prints pop off. For PLA the bed needs to be at 70c with this bed liner. ABS is good at 100c. Although it sticks too well so I sometimes print ABS at 90c on the bed. The steel spring was cut for a Prusa i3 MK3 so it will not fit between the gantree on the Ender 3 the normal way. I use it sideways and it fits just fine. You can also cut the sheet but I imagine a special tool will be needed to do a good clean cut of that spring steel.

What I did was I got a nice thick borosilicate glass plate from amazon, the one with the corners cut off so it fits the bed perfectly without the heated bed bolts interfering. Then I got a sheet of PEI with 3M adhesive on the back. I cleaned the glass with alcohol and then carefully applied the PEI so there weren't any air bubbles.

​

This is the glass:

​

And this is the kind of PEI:

https://smile.amazon.com/Gizmo-Dorks-Preapplied-Laminated-Adhesive/dp/B07GSJSDWR/ref=sr_1_4?keywords=PEI+sheet&qid=1555903728&s=gateway&sr=8-4

​

I have gone through a handful of these borosilicate sheets, and have had one or two that were warped. All of them were thinner than the Gulf Coast Robotics one. Theirs is bang on flat and way tougher, hands down the best. When you apply the PEI, make sure you do it very carefully as to not create any bubbles underneath. I started on the center of one edge and slowly applied from one side to the other, peeling the backing off as I went. Press it down from the center out as you lay it down and you shouldn't get any bubbles. Lots of very tiny bubbles are to be expected and work their way out after a while (Im talking really tiny). As for attaching the glass to the bed, a set of four binder clips are perfect. Don't bother with the thermal pads some people suggest, they make it a pain to remove the glass in between prints and don't really do anything.

​

This is a great way to have a removable build surface that everything sticks to. I have since moved up to a Prusa MK3, so I get to enjoy the luxury of the magnetic PEI build plate. You could get a similar thing going, BuildTak sells a magnetic build surface that you apply to the heated bed. The drawback of this is that if your bed is warped at all, the magnetic sheet does nothing to correct it. The thick glass on the other hand makes everything nice and flat.

​

I should add that to put the glass sheet on, you will have to move your z endstop switch down. There are several mounting holes on the printer to do this already so its really not that hard, you just have to experiment. The glass is about 4mm thick so you have to adjust for it.

Agreed. This was the best investment I could have made in my MPSMV2. I bought this one, there are cheaper ways to go, but I felt that the savings in time and fiddling around cutting glass was well worth the cost. Be sure you first print a 3mm gap adjustment device. I printed several including an adjustable one, but settled on this one from Thingiverse. I did not remove the black pad on my V2, I just use tiny binder clips to attach the glass to the bed. It leveled perfectly and heats very well.

​

I used a piece of 20 lb copy paper to set my nozzle gap, so even though you own a feeler gauge, I recommend checking it against a piece of paper. You want the first layer to be a flattened tube, not a round tube as it appears in your pictures.

​

Many people suggest Aqua Net hair spray, but my store only carried it in aerosol. I felt that would be a mess to spray onto the glass, so I got some pump hair spray that was right next to the Aqua Net on the cheap shelf (it had similar ingredients to the Aqua Net, primarily water). I spray the hairspray onto a paper towel and then wipe the cold glass to create a very thin film. I have found that the adhesion is excellent at 50-60 degrees, and the parts pop right off after the bed cools (using PLA, various brands).

I was having problems like this because of two different things:

Bed adhesion and my print bed lifting during printing.

I had reduced the number of clips holding down my bed surface on my ender 3 and what I didn't realize was that the bed surface was lifting during different stages of printing. If your print surface is removable you may want to make sure it is properly secured during printing. Even with 6 clips holding in place, though, you can still have some lifting in the middle of the bed. Even the smallest amount can cause major problems.

I fixed both of my problems by picking up a spring-steel sheet coated with PEI that mounts to a magnet that spans over the entire print bed. I got this one, but there are tons out there for all sorts of printers.

If you don't want to go the PEI sheet route, and if your bed surface is not removable, perhaps you simply need to change something else to improve bed adhesion, such as painter's tape, hair spray, glue stick, cleaning between prints with isopropyl alcohol, stuff like that. Not sure what you do currently.

Also, I recently dropped my fan speeds a TON. On most prints I have it turned off completely. Not sure if this is the best way to do things, but it has really improved the strength of my prints.

Hey I also new on this, got my printer a month ago, I was super exited as everyone here when receive their printer, I read a LOT while waiting for the printer, so I heard that the stock bed springs are crappy, so I ordered this ones FYSETC Bed springs, also ordered the Aluminium Extruder feeder, and read about the leveling, the paper sheath method, which I think you should already heard about, I did it at the first time the printer gave me a nearly perfect first print (demo dog) , after a few prints and on my third print I came home just to find a mess on my printer, so I did my research again, find out it was bed adhesion, and find out that the best way was glass bed + PEI sheet was the best option, while waiting to arrive I tried to clean the stock bed sheet with mineral spirits (did have rubbing alcohol) but it worsened the adhesion, so I used one adhesion sticker that comes with the overture filament, and again flawless adhesion, at least for the first 4 prints, then again the frustration, I tried some glue stick and worked but it leaves a mess on your print so I decided to try painters tape directly onto the aluminum bed (which lucky for me it is perfectly flat) this is the best adhesion I have tried, problem is also makes a mess with the down face of the print, Finally mi Gass-PEI arrived, (3 days ago), it has a great adhesion but is not perfect, also you have to raise the Z limit switch to compensate the 5~ mm of Glass-PEI, find out that it isn't perfectly flat it has a good adhesion and leaves a very smooth down face, but at some section it does't sticks well and leaves artifacts on the down face, I'm currently working to fix this.

Sorry for the long post, need to talk about my frustration and let you know you are not alone on this, once you manage to make a good print is very satisfying, I have a PETG filament waiting to be used but I don't think is a great idea to try it until a learn more about 3D printing and the Ender.

I developed chips in my glass build plate and put a PEI sheet on top of it. So far, loving it more than purple glue stick on glass. It takes a lot less bed heat for that sweet spot of good adhesion and fairly trouble free release. PEI sheet does take a very careful release process on large base builds to not damage the sheet. Tall builds often can be tapped off with the scraper handle.

Using PEI sheet over the glass plate made me realize a thin sheet of metal would be better. Aluminum didn't turn out to be a good surface to directly 3D print on, but an aluminum sheet covered with a PEI sheet should work great, since the aluminum would still be a good heat transfer. The combination of the PEI sheet over the aluminum plate removes all the critical specifics of them, by themselves. Easy removal, cheap, no gluestick needed, nice clean bottom quality (not mirror though). The combination of plate and PEI sheet is a dirt cheap build base.

I had this happen on mine. Scrape it off the best you can and use Goo-Gone to purge the remaining adhesive. Once you have a clean metal bed, painters tape works great and is cheap and easy to replace. If you are feeling up to it, you can install a glass bed on top of the metal like I did, just make sure to level the bed right if you do because the glass adds extra space. Then use a purple glue stick for some extra adhesion if you need it!

​

Here is the link to the bed I am using, and I am completely satisfied so far -> https://www.amazon.com/Borosilicate-Polished-Corners-Monoprice-Select/dp/B075XJ5ZP1/ref=sr_1_fkmr2_1?ie=UTF8&qid=1549203064&sr=8-1-fkmr2&keywords=monoprice+mini+v2+glass+bed

Paying someone to do the full set will definitely run you more than the cost of this printer. It's the printer I have. It's a bit finnicky, but the price is right, and it prints well enough for me! I'd also highly recommend getting a glass bed for it. It's stupid easy to install the glass bed (you just lower the normal bed and clip the glass to it with binder clips), and it makes the prints come loose soooo much easier. You can also have a hardware store cut the glass for you and it will be a bit cheaper than that Amazon link.

I will say, though: I only recommend buying a 3D printer if you're willing to devote some time to it. It's not like an InkJet where you plug it in and it just works. It takes calibration, and learning which settings work best. You'll have to do some research to get the best quality for your prints.

As far as the bed wiring goes, it's a common problem for them to get pinched due to the way they are routed and mounted at the factory. This usually ends up in an opening in the circuit (either in the heater or the thermistor wires, or both) because the wire inside the insulation has actually broken. If your bed temp reading shows 0 or 999 during printing or preheating, it has happened to you. This guide helped me with rewiring and rerouting the bed wires to eliminate this problem when it happened to me. If you're not comfortable with soldering it yourself there even a link in there to where you can buy a whole new bed with the wires already soldered on. Then just print the parts they recommend for the new side panel and you're good to go! Also, since I soldered my wires directly off the back of the bed I went with a center mount for the cable brace grommet, there are remixes to the one linked in the guide. As a final note, I recommend a glass bed, this is the one that I got and I just hold it on with small binder clips. With that, a bit of glue stick, and the heated bed, I'm getting the best adhesion I could ever need. After a print is done just throw it in the freezer for 30 minutes and it will pop right off. If you've already seen all this but haven't taken the time to do it, just do it! It's definitely worth it. If it's new info for you then I hope it helps. Happy printing!

The Monoprice Maker Select V2 goes on sale regularly for less than the normal $350 price tag, I got mine for $312.

However, if you don't need the larger build area (180x180x200mm) then the MP Select Mini is only $200 and a definite recommendation from me. It has a smaller (120x120x1200mm) build area, but the quality is pretty much the same as the other printer. I have both and can directly compare them.

Both options have a heated bed, and the maker select v2 comes with buildtak (or a knockoff of buildtak, still works) but you can buy a 3-pack of 6.5" buildtak from amazon for under $20 and cut it to fit the mini.

I've mentioned it in several posts before, here are some of the reasons why I recommend the mini.

• It's sturdy as hell, because it's all metal.
  
• It has a small-ish build area but for most projects it's enough. (120x120x120mm)
  
• It can print faster than monoprice says it can. 75mm/s easy.
  
• It has wifi but monoprice has that disabled. *
  
• The bowden style extruder (extruder on the frame, instead of moving with the hotend) means good quality prints at higher speeds than with most other extruder styles.
  
• Simple user interface, you decide whether that's a good thing or not.
  
  * As for the wifi, this printer is a rebranded Malyan M200. You can get the wifi firmware from here. Follow the instructions in that folder and you're good to go. Then use the android app found here to set it up on your network.
  
  The wireless interface is even simpler than the normal one on the printer, for better or for worse.
  
  It also comes fully assembled, just level the bed, insert filament, and print. The maker select v2 requires some assembly, but it's literally just bolting two pieces together and attaching the filament spool somewhere.

PEI, Polyethylenimine, is a type of plastic and you can buy it in various forms (including sheets). It's handy because it's nice and sticky to plastics like PLA when it's heated but releases well when it's at room temperature (a few taps along the edge of the base of the print releases most things). The only issue I've had with it is that TPU sticks a bit too well, but TPU's really best printed on a pure glass bed anyways.

I've got a sheet of PEI adhered to a glass sheet and clipped to my print bed. It works great.

Here is my CR-10S.

I added the Petsfang fan fang. Added this fan to the fang.

I added these Z-Axis braces. Added these LEDs to the Z-Braces.

I'm printing on a mirror tile with a sheet of PEI bonded to it.

Last week I added the TH3D EZABL and have been encouraged by the results. It creates a Z-offset map of the build plate before every print. I can see the Z-steppers move during X-Y moves so I can tell it's working. Manual bed-leveling was working OK for smaller prints, but I could never get all 4 corners to agree with the center height. I suspect my aluminum bed plate is shaped like a Pringles chip.
I really like the Marlin Firmware over the OEM version. I don't mind not having auto-resume since I plugged my printer into a UPS system.

Right now my printer is about 20 hours into a 60-hour print of a T-Rex skull. I've been really happy with this printer! It was my first and I've been having a ball with it.

I had a problem somewhat similar at times. My ender 3's bed was a bit warped. The buildtak surface worked well (never used tape) but yes, prints were a bit difficult to get off without scraping and damaging myself or the bed surface sometimes. So i bought this: https://www.amazon.com/gp/product/B07F6CLTD7/
And it has changed everything. As long as you get the bed heated up to 60 degrees (and let it sit for a short bit to make sure the actual glass is that temp) you will get fantastic, flat, first layers. And prints that pop off on their own once the glass cools down. Warning, make sure the nozzle doesn't scratch the glass and don't use sharp spatulas on it. I bought these: https://www.amazon.com/gp/product/B075SLTY8B and they work perfectly. Thin, not sharp, flexible, pops things off no problem, even if the bed isn't cooled down.

Hold the glass to the bed with some tiny binder clips. Just make sure the print head doesn't run into the clips and you're good. I ended up changing out the cooling set up so that i had a thinner profile around the extruder to make sure i lost less print area due to the clips. I printed this: https://www.thingiverse.com/thing:2911981 and like it, but there are many other fang style ones out there.

For leveling i use a piece of printer paper, folded over. Took calipers to it and it's about .2mm in that set up and i level just so the nozzle scratches the paper (not holds it) and that seems to work for me.

The build plate on the Ender is made of aluminum and is infamous for warping under heat, or just being slightly bent out of the box. Whereas a glass bed sits on top of the aluminum build plate.

Most people use glass for the smooth surface, but many Ender owners choose one simply because it provides a level printing surface. Often people will even put the print mat that comes stock on top of the glass, giving them the adhesion benefits of the mat, with the level benefits of the glass.

Some will tell you that a mirror or similar piece of hardware store glass will work fine, but it is known to shatter due to the heating and cooling process. For about $20 on Amazon, an actual Creality borosilicate plate is well worth the cost. (on Amazon )

Those couplers are trash and so is the PTFE tube they sent. They may work for a while but you'll want to swap them sooner rather than later. Here's a list of upgrades you'll probably want to do. You'll also want to look up a tutorial on how to upgrade your firmware so you can activate safety features (thermal runaway protection specifically). This also doesn't include a BLTouch or EZABL (auto bed levelers) as I have yet to make a choice personally.

The pei sheet I got from amazon (https://smile.amazon.com/gp/aw/d/B074XLD5QH/ref=ppx_yo_mob_b_track_package_o0_img?ie=UTF8&psc=1) didn’t have the adhesive pre-applied, it was just smooth on both sides with a thin film over it for protection, and a 3m double sided tape was included in the package. If yours has adhesive already on it, I’m not sure about the temp limit on the film, but suspect you’re right that it isn’t very high.

I had been thinking about just clipping it on before it arrived, but it was thin and flexible enough that I’m pretty sure it would get pulled up slightly by larger prints. I had considered just buying a 1cm thick sheet from McMaster Carr or somewhere rather than one being marketed for 3D printing, I think you could definitely clip that since it would be rigid, but I was concerned if it didn’t show up perfectly flat I wouldn’t be able to do anything about it.

I watched a few videos before putting it on, and it was actually easier than I expected. Even though it has some flex to it, it’s ridged enough that there wasn’t really any issues with bubbles under the pei sheet itself. The adhesive bubbled a little when I put it on the glass, but it wasn’t very hard to either work them out, or in a few cases just poke them with an xacto. The hardest part was actually removing the plastic from the top of the adhesive without peeling the whole thing off the glass, but once done the pei went on nicely. If you’ve seen them mounted before, it’s normal for it to look kind of mottled with some visible pockets of air, but still be flat with no significant bubbles. I checked for flatness and it was good. I will take a picture later and update this so you can see what I mean.

I’m jealous of your 2 backups, I have been afraid to print anything but PLA and be unable to get it off. I ended up with the pei because I kept destroying various stick on surfaces by squishing the first layer of PETG too much and ending up with it welded on.

Look into purchasing a PEI (Polythermide) sheet to put onto your printing surface. I did so and it works incredible!

Just make sure that you take your time while applying it to reduce the amount of air bubbles. I picked up this kit from amazon: https://www.amazon.com/gp/product/B01KGDTPQK/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

Edit: It takes virtually no maintenance, and everything sticks to it incredibly well. I also forgot to mention that I have only tested it with ABS, but I hear PLA works well too. I have also heard that PETG sticks better than ABS or PLA.

Edit 2: I also should mention that I was able to stick it directly to the aluminum bed. Make sure to clean it really well if you do plan on taking this route.

Hotend replacement:
I replaced the stock hotend/PTFE tube setup with an all-metal Micro Swiss hotend ($50):Amazon link to the Micro Swiss all-metal hotend kit: https://amazon.com/gp/product/B01E1HANLS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Bed leveling:

1. Most importantly, I purchased a glass bed to eliminate the never-really-level printbed.Amazon link to the borosilicate glass bed ($25): https://amazon.com/gp/product/B07BHG5HCV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
   
   
2. Since that didn't I completely fix the warped bed issue, I also replaced the aluminum Y-carriage underneath with a thicker, stronger carriage and my bed leveling is now perfect. I still re-level before every print just in case, and now never have leveling-related problems.Amazon link to the aluminum Y-carriage ($28): https://amazon.com/gp/product/B07B251KBS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
   
   Frame Stabilization:
   I printed the parts, and purchased the hardware at Home Depot for the Z-brace mod, which stabilized the printer frame:Thingiverse link for Z-brace mod for I3 Plus: https://www.thingiverse.com/thing:1653631(note the original Thingiverse link in comments, which is required for the other Z-brace parts: https://www.thingiverse.com/thing:921948)
   
   Cooling:
   I printed a Dii Cooler in PETG and replaced the stock cooler with one of those 24V "squirrel cage" fans, which provided much better cooling for all sides of my prints. Before that it really only cooled the front of prints, leaving the sides and especially the rear of prints looking pretty bad.Thingiverse link for Dii Cooler for i3 Plus: https://www.thingiverse.com/thing:1025471

I struggled with adhesion for the first couple weeks of printing. Then I swapped my stock bed for a glass + PEI combo. Got the flatness of the glass + the adhesion of the PEI. Once the plate cools down a few degrees, the parts come right off. No need for sticky hairspray to get things to stick, and no need to put the bed in the freezer to get things to unstick. Best upgrade I’ve made on my ender 3 (~$30 total). Always wipe down with isopropyl alcohol in between prints for best adhesion.

Tip: I also recommend gently wet sanding the PEI. Helps with adhesion and creates a very nice matte finish on the first layer.

Idk about $180, but you can definitely save a bit of money if you order it from the warehouse in China. It just takes longer to arrive, and I personally feel more comfortable dealing with Amazon, as compared to eBay or Alibaba.

OP, here are a few purchasing option links. Also, I would go with the glass bed option if I were you. The eBay link has the option to choose "Ender 3 + Glass Bed" at what looks like no extra cost. Otherwise, you can buy the glass bed separately for less than $20.

I'd recommend applying the pei in the smooth side of the glass that way you can flip it over to have the textured side if you want.

Hey! I got the same printer and was using ABS for my first couple prints. Couple things--First the built in items on the SD card are sliced for PLA printing, so you need to up the temps on the extruder and bed--I had success just upping it to 240/80. This got it to stick, but I had to get my z positioning (the thumb wheels on the corners) just right. Also I absolutely needed a raft for anything to really stick.

If you're slicing your own items in Cura, the default filament size is 2.8mm and you're probably using 1.75mm filament.

Unfortunately on any prints longer than an hour the ABS would start to curl off the bed--I chalked that up to the somewhat breezy room I have my printer set up in currently.

tl;dr Make sure your bed/z is leveled precisely so that a piece of standard printer paper can slide underneath the nozzle in each corner with resistance. Try upping your temps and checking your slicer settings as well.

/u/Redditull mentioned a glass bed. I picked one up on amazon, this fits the bed pretty nicely (just lays between the corner screws)--you do need to raise your z-stop, there's a metal lever contraption screwed into one of the sides of your printer's frame that you need to unscrew and raise. I also attached a PEI sheet to this and I used thermal pads to attach all this to the bed. This all improves adhesion greatly, I've mostly been using PLA after the difficulties I had but I would imagine ABS would stick just fine as well.

Borosilicate Glass

PEI Sheet

Thermal Sheet

Sure, no problem. I'll give you a bit more info as it may be relevant :)

1. I use a 3 mm borosilicate glass bed by Go 3D. I started with dollarstore glass which worked well enough but it wasn't thick enough to compensate for my curved bed.
   
2. I washed it in hot water and soap. I had to use a razor blade to scrape off some tough weird spots that were likely from the manufacturing process. I got it squeaky clean and let it air-dry.
   
3. Meanwhile, I removed the buildtak and adhesive from the printer. It didn't take long. The trick was heating the bed up to 100 and carefully using a razor blade scraper. I have more info on this; ask if you're interested.
   
4. I installed the glass bed, making sure I didn't touch the surface more than necessary.
   
5. I cleaned it again with 70% isopropyl and a glasses cleaning cloth (I picked up a bulk pack of them from Amazon). The isopropyl is in a spritz bottle that I bought at a local drugstore. I top it up using a bigger refill bottle.
   
6. And that's basically it. I repeat #5 every time I print. Spritz, scrub a bit with the cloth over where the previous print was, and done. It takes maybe 10 seconds. I've been printing on it for about 2 months now and haven't taken it off to re-clean with soap and water. Some people say to use acetone, but I've had luck with just 70% iso.
   
   That said, the biggest contributing factor to getting my prints to stick was the leveling. Once I nailed the leveling, I haven't had a failed print due to poor adhesion. Failures due to other things, sure. But not because of the glass :)

I'd recommend glass, some binder clips to hold it to the bed, Elmer's purple glue sticks for adhesion, a heat gun if you live somewhere like the South and it takes forfuckingever for things like glue stick to dry (I don't have this exact one but I'm sure it'll work just fine), and a spray bottle of water and squeegee to clean all of that off every few of prints.

Also as everyone else suggested, a Pi 3 for Octopi. I'm using a 32 GB microSD that I had laying around. Just send prints from Cura to Octopi! A camera is pretty cool for time lapse shots too! I'm pretty sure this is the one I've been using, but I really don't like the one mount I've found for it so I'm going to switch to my Logitech C615 after my daughter goes to bed and I can fuck around with my setup... ;P

I replaced the stock glass with mirrored tiles from Home Depot. I used to use tape and glue sticks but read a comment on how much better PEI sheets were to print on. No more glue or tape, just rub it down with rubbing alcohol between prints.

It sticks very well when heated up, and comes off almost effortlessly when cooled down. You also get a shiny surface on the part touching the PEI sheet which is nice. Well worth $21 from Amazon.

So far, comments have focused on the glass bed. FWIW, your bed seems similar to mine:

https://www.amazon.com/dp/B07RD6D2ZQ

I've had at least 1000 successful prints on the "dimpled" side of this bed and have never used any kind of adhesion aid. I clean it with a quick wipe of alcohol (for one or two seconds) between prints and it's good to go again.

My guess is that you still haven't managed to level your bed properly. Can you upload a pic of one of your attempts at a first layer? That would help a lot.

Its a great printer. Upgrade your springs and get an aluminum extruder. Those two things were so cheap, but definitely made a difference for me. I use a glass bed with a PEI sheet and have been very happy with it. I use eSun PLA Pro for my minis. Check out Tomb of 3d Printed Horros for their cura profiles and tips!

I LOVE MY ENDER 3'S. I have one running stock everything (except the bed) and the other is well, an ender 3 in name only now. (I know you mentioned you are in the EU, but I have provided links to my sources for US based distributors)

Note that I didn't buy this flashing kit, but this one seems to have everything you need to get a bootloader onboard the Ender. What happens is you go through a bunch of steps to attach this so the printer and then put a bootloader onto the Ender 3 board. You only have to do that one time, then you can update the firmware as often as you want - typically via a USB cable. I have Octoprint installed, so I can flash my firmware on my basement printers from my upstairs computer using wifi. Super easy and handy.

I bought a regular glass bed off amazon and really liked that but the textured surface started to fail after a while and I didn't like having to clean off adhesives or hairspray. I got this PEI build surface from amazon and stuck that on top of it. The ender 3 pro's magnetic bed base is enough to keep the glass in place and the PEI sheet has adhesive on the bottom of it so I don't need to use the binder clips like I thought I would have to at first. It all just stays in place without shifting and I have access to the full print bed. The glass is still on there to correct a warp in the base bed and the PEI is honestly such an upgrade from glass. Things stick with no effort and come off easily at the end, except PETG which sticks like nobody's business and is harder to remove.

This actually happens because the air gap between the raft and the print is too big, however, if you make it too small your raft will not come off. I recommend what most people say about a better build surface.

Personally, an 18$ glass build plate from amazon has worked wonders for me, better than any painters tape or buildtak.

I add a generous amount of hairspray and let it heat up to dry.

If you are interested, here is the link to the glass plate:

https://www.amazon.com/BKM-130mm-160mm-Borosilicate-Select/dp/B07BYJQH79/ref=mp_s_a_1_fkmrnull_4?crid=26O8O6WR9UIGU&keywords=bkm+130mm+x+160mm%2C+3mm+thick+borosilicate+glass+plate%2C+select+mini&qid=1550989157&s=gateway&sprefix=bkm&sr=8-4-fkmrnull

I bought a Davinci 1.0 last year when it was on sale at Amazon. Flashed Repetier on it, and I've been cranking out a ton of ABS stuff with it.

To make things stick I've been using buildtak. Works really well, but make sure you re-calibrate your bed, because it will add some height. If you print to close to it, the plastic will go into the material and fuse with it, making both the buildtak and part unusable.

Best $20 bucks you can spend imho.

I had good luck with this glass with the corners pre-cut:
https://www.amazon.com/gp/product/B075XJ5ZP1/

Don't forget to get this to help transfer the heat from the aluminum to the glass, also helps as a non-slip surface to help hold the glass in place:
https://www.amazon.com/400mm-205mm-Silicone-Thermal-Heatsink/dp/B007PPEW52/

I ended up ordering a generic borosilicate glass bed and applied some GizmoDorks PEI to the top of it. Works excellent and I don't need to use any painters tape or glue stick with it. It was a great upgrade from stock and much easier to level. Haven't decided yet if I want to dump my dial indicator leveling for a BLTouch or equivalent. I might end up doing that though.

I have a thermal pad sandwiched between the glass plate and the bed and it provides decent friction to keep the plate on but I also use two metal bag clips in the front and back to make sure the plate is pressed against the bed.

Glass Plate: BKM 130mm X 160mm, 3mm Thick Borosilicate Glass Plate, Select Mini

Alternatively, I've heard of people using glass they cut from a picture frame using a glass cutter

Thermal Pad: uxcell 400mm x 205mm x 0.5mm Silicone Thermal Pad for CPU GPU Heatsink

Not entirely necessary but supposedly this helps transfer heat more evenly and you get a huge sheet so you can get like 4 uses out of it if you optimize your cutting.

You can't, I've destroyed mine and installed PEI.

https://www.amazon.com/gp/product/B01KBGJU5S/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Stick it down with this stuff here:

https://www.amazon.com/gp/product/B007Y7D5NQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

When you use this stuff you just wipe it with rubbing alcohol to clean the surface. Then it gives you near perfectly smooth prints where it touches the surface. The prints pop off easy after it cools but holds tight when it's warm. Personally I find it a waste of money to buy glue sticks/hair spray if you don't have to. Although I did buy glass I never installed it after this worked so well. It's amazing stuff and you'll never have to replace it.

I bought a pei sheet off Amazon and just clamped it on top of the original surface. No need for glue or hairspray or anything like that. It sticks perfectly and when it cools down it pops right off.

Would recommend it to everyone.

Gizmo Dorks PEI Sheet, 8" x 8" 3D Printer Build Surface Polyetherimide Ultem https://www.amazon.com/dp/B01KBGJU5S/ref=cm_sw_r_cp_apip_IA4KofJ8WMGmf

This happened to me after a while as well. The solution was to buy a piece of borosilicate glass like this https://www.amazon.com/dp/B07BYJQH79/ref=cm_sw_r_tw_dp_U_x_NF3CCbCG26B3V and clip it on with small binder clips. I even ended up putting a piece of buildtak on top of my glass because I really like buildtak but needed the perfect flatness of glass.

I've also had issues due to bad tape. The green frog tape is horrible. Before I got my PLA sheet, I used the cheap wal-mart type wide blue painters tape and it worked great. I liked to use kapton, but it's just too delicate to last very long. I was changing it out every 2 weeks. PEI is the answer (waay tougher than buildtak)...lasts about a year and everything sticks to it. Also, since PEI has such good adhesion, your z level is a little more forgiving for that first layer.

https://www.amazon.com/Gizmo-Dorks-Printing-Surface-Adhesive/dp/B01KGDTPQK/ref=pd_lpo_vtph_328_bs_img_2/136-9930884-8852130?_encoding=UTF8&psc=1&refRID=B25F74EX68VYED1NFMY2

I'm actually planning on getting this pei sheet, https://www.amazon.com/dp/B07FVL1SYF/ref=cm_sw_r_cp_apa_i_Udh8CbRYZ36M4

The BLTouch works very well for me, I did a big write up on the forums about it and somewhat maintain a repo for the firmware on GitHub. Pretty sure I need to change the step values back to default though, can't remember if I've done that yet.

When you get the Monoprice I recommend getting a few sheets of Buildtak for the bed instead of using the tape sheets it comes with. It will make print adhesion much easier and is worth the investment in my opinion. Other than that I would say pick up a spool of PLA to get started and have fun.

He means like this, adhered to glass, or directly to the heater.

I'd personally recommend glass with hairspray. Best print bed I've gotten yet!

To increase your chances, make sure you use some quality PLA. The difference is in the chemistry and the quality control. I'm getting some great results with MatterHackers PLA. Pro grade, I think it's called.

Happy to be here the day the thread was created.

I'm looking at some improvements for my Wanhao duplicator i3. I'm looking for new nozzles, a new fan, and a glass bed. This'll be my first time modifying the printer other than adding the heating bed mosfet.

Also I recently learned that hatchboc lists their PLA as having a +-.03mm tolerance when in reality it's .05 and they charge enough that I could've been going with amazon basic this whole time. So I'm looking for a new filament manufacturer.

These are the nozzles (amazon link) I was looking at. I'm still using the .4mm the printer came with and I'm planning on using the smaller sizes mostly. My question is is this a fair price for this range (two each, .2 .3 .4 .5 .8 1.0) of sizes? Nobody is talking about the durability in the reviews (which are all 5 stars so I'm extra cautious) so what should I be looking for? They're all brass which is what I'm used to, and I'll I've ever really heard of.

This is the fan (banggood link) I was looking at to go with the cooler (thingiverse link) I've been using. Not too concerned with this buy. Just wanted to see if anyone else is familiar with the seller. I haven't spent much time on it but if I can find the same fan with prime on amazon I'm probably going to jump on it.

This is the glass bed (Amazon link) I was looking at. It's been months since I've worked with a glass bed and I don't really want to use binder clips. I was looking at this thermal pad (Amazon) and I have no idea what to look for. The size is what I'd expect but is there some spec I should be looking for? Is silicone just silicone and I should be buying the cheapest thing I can find? I believe I have the tools to cut the corners on the glass myself so I'm not too concerned with that.

That you for the read! Sorry I have so much I'm trying to be very careful with all this.

I've been using a sheet of PEI that works like a charm. The one i got was from amazon, something like this would work https://www.amazon.com/Gizmo-Dorks-Printer-Surface-Adhesive/dp/B074XLD5QH/ref=pd_sim_328_3?_encoding=UTF8&psc=1&refRID=PPGSHY9T4C0YC14V4FVS

It even comes with the adhesive.

The first thing I did when I got mine was replace the stock extruder fan with a radial fan + a diiicooler link

I also printed a z-axis stabilizer

Upgrading the to an all metal hot end is also a solid choice

Getting a pei sheet and a piece of borosilicate glass for your build plate will help too.

as someone brand new to 3d printing--

I just bought an ender 3 last week... I hear a glass bed and aluminum nozzle are crucial upgrades.. Looks like a couple third party ones are discounted for prime day-- are any of them worth while? Is there a difference?

These two things took my prints from adequate to pristine. Huge improvement.

I would recommend Gizmo Dorks on Amazon, it's a bit more expensive than others but it's pretty thick at 0.56mm and quite durable.

It can be purchased cheaper from other vendors, but those are much thinner pieces at 0.1mm, which I imagine wouldn't last as long. Another perk of PEI is if it gets scratched or ends up with surface defects, you can sand them out and it's good as new. Thicker sheets will obviously handle this better as there is more material.

It's multiples of 0.04, but it won't have a huge impact.

Regarding hair spray/glue stick etc... a PEI sheet will save you a lot of effort. You put it on top of the glass and then print directly on it, no need to do anything. Edit: and yes, as /u/PuterPro says, get your bed flat.

I love my PEI sheet, at first it was strong enough I had to put my glass in the freezer to remove prints, after a while it dulls a bit, but if you sand it lightly it'll make it grippy again. Also alcohol / acetone wipe down every once in a while helps.

The one I use:

https://www.amazon.com/dp/B074XJLWL6/ref=cm_sw_em_r_mt_dp_U_gSfsDbWX1S36A

I've tried clips with glass. The problem is your printhead and/or cooling fan will hit the clips unless you're really careful. I recommend the silicone thermal pads.

http://3dprinterwiki.info/wiki/wanhao-duplicator-i3/duplicator-i3-basic-mods/adding-a-glass-bed/

I've also tried hairspray on glass, and gluestick on glass, and painter's tape on glass. To hell with all of those, it's always either not sticky enough, or too sticky. Get yourself a sheet of PEI to put on your glass. It's soooooo much better than anything else. Perfect adhesion while printing, then your part just pops off easily when it's done.

Thermal glass $12: https://www.amazon.com/Signstek-Printer-Heated-Tempered-Borosilicate/dp/B00QQ5Q3BI

PEI + adhesive $17: https://www.amazon.com/Gizmo-Dorks-Printing-Surface-Adhesive/dp/B01KGDTPQK

This is the most important one IMO. Eventually you should switch to a glass bed. It's pretty trivial, you just print a shim to change the z end stop and clip a glass bed overtop the buildtak (at least that's what I did).

A new fan shroud is worth doing

As is this little plate

Speaking of, are you aware of the magic numbers? You can find them with an explanation here: https://www.mpselectmini.com/optimal_layer

It's strong the best way to remove the print is let it cool and it comes right off most of the time. I have put it in the freezer and it made it easy to get a stubborn part off.

I use a spring steel magnetic bed now and it is better than the glass and the PEI combination but more expensive and I use a BLTouch prints pop right off with a little flex of the steel.

Borosilicate glass has high heat tolerance and is resistant to rapid heat changes. The one posted here fits perfectly on MPSMv2

I recommend a PEI sheet on top of the glass. I get really nice first layers using it. This is the one I use: https://www.amazon.com/gp/product/B074XJLWL6

Got my spring steel from Amazon. My PEI also came from Amazon, but I wanted to get it from a seller with more hits than misses.

You might be asking the wrong guy here, but having used Flashforge, Raise3d and E3d v6 hotends previously, the mosquito is far and away my darling favorite. I don't know if it's "worth it" but I would not print without it at this point.

https://www.amazon.com/dp/B07FVQJ7QK/ref=cm_sw_r_cp_apa_i_IYxZCbFJJBGK3

This is the exact one i got from amazon, comes with an adhezive side, pretty easy to apply, and it seriously made a massive difference with adhesion.

Don't use glue sticks, use nothing or just use hair spray, it's much easier. Both suave and aqua net have worked for me. You also don't need to use windex, just use alcohol, and you don't even have to clean it every time.

Seriously though as great as glass is PEI is just so much easier to deal with. This is the one i have, but you can also buy them from Prusa (which is what I am going to do next time I buy one).

It's CCTree on Amazon. I'm not unhappy, but it's not what I thought it was. It has a textured side, and a side with an adhesive to stick to the metal bed. The reviews mentioned one side being smooth; which is what I wanted. I have thought about trying to remove the adhesive, but haven't gotten around to it. The textured side has done really good on adhesion issues with PLA, but I was really wanting the smooth surface for the bottom

https://www.amazon.com/dp/B074XJLWL6?ref=yo_pop_ma_swf this isn't an affiliate link or anything, just copy and pasted from the amazon app. I had to cut the sheet down a bit. It scores and breaks pretty nicely. Keep in mind it's about 1mm thick though.

I purchased this build plate and was upset when this kind of gel coat came off of it with alcohol. I cleaned it off a kept using it. I love it now. It still has a coat on it. For small parts i still use a glue stick just in case. I got the blue springs also. Its a good set up. I never got 1 good print from my removable bed.

Mine worked great without having to scuff it at all. I just heat the bed to 60°, when the print is done and the bed cools down the print pops right off. Here is the link to the one I bought.

I just ordered one the other day after doing lots of research. This one has great reviews: https://smile.amazon.com/gp/aw/d/B07RD6D2ZQ?ref=ppx_pt2_mob_b_prod_image

Do some youtubing and googling. Never need glue or hairspray again.

I have a glass bed, too. What I do is, once the print's finished and cooled down to room temp, I throw it in the freezer for about 15 minutes. The print just pops off. In fact, most times it just falls off.

[edit] It also helps that I bought this, the edges are already fairly rounded, plus since it's the same material as Pyrex®, less chance of breakage. You can look his store name up on Google, he usually has them available there when he's out on Amazon.

• Printer: Ender 3 Pro w/ glass print bed
  
• Print material: PLA
  
• Temps: nozzle 220, bed 70
  
• Firmware: whatever came on the printer by default, using Ultimaker Cura for the slicer
  
  I recently turned up the temps a bit because I was having first layer going down badly, but I think I over did it a bit and it's giving me a bit of stringing. Other slicer settings tried changing:
  
  
• jerk: 8 mm/s
  
• acceleration: 250 mm/s^2
  
• feed rate: 60 mm/s
  
• layer height: .2 mm
  
  The thing that's been driving me a bit crazy is getting the front of the boat there to have a nice smooth surface. The surface didn't really seem to change that much with the reduced jerk / acceleration. What are some things I can try changing to help improve the print?

You should try Buildtak. Its a really good surface for printing on PLA. Its all I've used for the past year. Just stick it to your metal surface, then use a paint spatula to remove the raft prints and your set!

Can we a get a closeup of the first layer only? It will help if we can get a really good look at the size/shape/texture of the first layer extrusions.

Tape and glue and everything can work, but it's always been a huge hassle for me. https://smile.amazon.com/BuildTak-Printing-Build-Surface-Square/dp/B00MN5X304 might be worth a little money. In my experience that printer does just fine with buildtak and a hot bed, as long as you have your nozzle height dialed in and the bed leveled. It might be worth $20 just to remove the surface material from the equation.


As for the nozzle wiping bit, that's a huge pain in the ass. If you're up for learning a little g-code (it's not hard), I recommend changing your pre-print g-code to move the nozzle directly onto the bed during the heatup phase, this keeps the goo in and makes your life a lot easier.

Also, you should change your skirt distance to about 15mm. The point of the skirt is to prime the nozzle. Moving the skirt away from the part will increase the skirt path length, which means more priming, which means you won't have to restart prints after a bad start as often.

I'm using this with my Monoprice Maker Select V2. I removed the build-tak and installed this. (First I installed the 3M adhesive to the PEI, then the PEI to the printbed.)

Main thing I changed was going from a 50c bed to 60c (Sometimes 70c)

I've never had great luck getting adhesion straight on glass, but the glass will give you a flat bed. If you have adhesion issues, go with blue tape.

Glass will make the bed flat but not level. You still have to do that part. It will be much easier to level and require less frequent adjustments though. There are pre-cut pieces of borosilicate for the mini

I bought this one and it's been working great. It's thick enough that it can take some prying and if it starts to lose adhesion you can lightly sand it with some 1000 grit to restore it.

In place of it. Really strong adherence to the surface too, without much heat needed for the bed. I did find I had to tighten the bed a bit more, since there's a bit of give to the surface vs glass.

This is the kind I bought - PEI Sheet from Gizmo Dorks

I prefer the etched ones like this. Great adhesion and if you print on the bare glass, the prints just pop off at around 40° C. Printing with hair spray, or even worse, glue will make your mileage vary.

I have them on both of my Enders and a very similar Ultrabase on my Tornado.

*edit added I do use.

for your size, this would be the easiest solution.

You just wouldn't be able to sand it. But it can still last a long time if you're careful with it.

I want to clarify that when this person is saying "PEI over glass" that this person is saying to put PEI [on top of] borosilicate glass, not in place of glass.

A sheet of PEI with 3M 468MP adhesive tape to borosilicate glass is a game changer. Use simple binder clips to keep it on the bed.

------

Edit: I stand corrected. OP was genuinely saying to use PEI instead of glass. I don't suggest adhering PEI directly to your plate because you're not always going to want to print on PEI depending on your material, and PEI will eventually get bubbles and warp and you'll want to be able to replace it.

Source: Have used PEI for over a year now.

Oh haha sorry.[ Gizmo dorks] (https://www.amazon.com/gp/aw/d/B01KGDTPQK/ref=sxts1?ie=UTF8&qid=1483410646&sr=1&pi=AC_SX236_SY340_FMwebp_QL65)

I sprung for a sheet of PEI and it's been great, buffed it with ultrafine steel wool and wipe the bed with isopropyl alcohol before each print. no tape, glue or hairspray needed.

I’ve been using this one all year

Some folks use binder clips to keep their on, I prefer silicon thermal pads (see the frequently bought together section)

You’ll also want hairspray or glue sticks. I use a purpose-made product called magigoo that helps with adhesion at the start of the print, then pops right off once the build plate cools

For the bed, I did a removable bed plate from here:

https://www.printfab3d.com/product/profab-removable-flex-bed-system/

For the actual print surface I did choose PEI:

I got you fam. Amazon!

This is what I use, installed on Day 1. Never had a problem with bed adhesion printing at 65, in fact it often sticks too much!

I recommend a PEI sheet

Yep, just got this glass bed since the stock bed was lower in the middle on mine. Works great, no more leveling issues. I still have the stock springs though, they seems to work for me but I haven't printed much yet to see how long they hold.

PEI is cheap and reliable.

Combine that with magnetic sheets and hey-presto, you got a removable flexible print surface to pop your prints off of

I bought the glass off of amazon:
https://www.amazon.com/gp/product/B075XJ5ZP1/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I'm using hairspray on the glass.

I had the exact same issues. A glass bed, thermal pad, and aquanet hairspray (yes, two is cheaper than 1) fixed it and I haven't had bed adhesion problems since. In fact, I have to use a flat razerblade just to get prints off the bed sometimes, lol.

>oes stick hella hard if you use a glue stick, but when I've used no glue and PLA, then let the print cool down, it slides off with no effort

​

So something like that? Id prefer to do as little mods as possible but im noticing glass it defiantly needed as the prints are hard to get off.

I can't suggest using glass with a PEI sheet enough Get a sheet of glass cut at lowes or the likes for under 5$ (I think i paid a little over 3 bucks) and just grab pre cut PEI sheet if you want you to pay a little extra for it. the entire set up should cost you under 20$. You will have 0 adhesion issues with PEI and the prints just pop right off once the bed cools off, not to mention your first layer will be smooth as butter and you'll solve most if not all weird warping issues by laying a plate of glass on the ender bed.

For the glass bed I recommend getting a borosilicate glass. It’s that the old Pyrex is made of. Resist heat differences without shattering. Here’s the link of the one I got. 130mm x 160mm Borosilicate Glass Plate Bed Flat Polished Edge w/ Corners Cut for 3D Print https://www.amazon.com/dp/B075XJ5ZP1/ref=cm_sw_r_cp_apip_tn7G8jRd96iU2

Mine came with 3m already on the backing so I just had to carefully apply it to the glass.

Gizmo Dorks PEI Sheet 3D Printer... https://www.amazon.com/dp/B07GSJSDWR?ref=ppx_pop_mob_ap_share

I don't know where you tried sourcing the glass, but a sheet of borosilicate is only $11 on Amazon, which is just $1.74 more than the Buildtak I found (which comes in at 3 for $27.75), and doesn't wear out.

It specifically says the dimensions fit the MP Select Mini well, and the cut corners clear the adjustment screws. The biggest problem I have with the piece I bought is that I have to hold it in place with binder clips on the edges. In order to not rub on the printer axis parts, you need to take off the binder clip handles, and in order to clear the print head, you need to move them as far towards the edge as you can. So it's a bit of a pain when they happen to pop off from vibration or hitting the print head. The larger piece I linked should mean you can clip from the front and back instead where mechanical interference isn't a problem.

People will say it's dumb to spend $20 on a print surface for a $200 printer, and that you can get away with a piece of frame glass for $1.50 instead. They're right, but it's a pain, and $220 for a printer with an excellent surface doesn't seem like much of a ripoff to me.

This one?

How are you finding the adhesion? The buildtak I have isn't very forgiving. at .08mm from the surface I can't get it to stick. Going to try .06mm

No just buildtak

The problem is that people still refer to information from 10 years ago in regards to 3d printing and wont let go of it. Hairspray and glue stick are one of those ideas that needs to be buried.

Buy some PEI

and apply this to your glass. Then just wipe it with isopropyl once and a while.

Then the only time you will use gluestick is when you want less adhesion. To give you an idea, I can turn on my heated bed and get old prints to stick again.
