This stuff glows SUPER bright and is a pretty decent transparent blue color. Glows bright electric blue under UV light.

I went with this

Blu by Siraya


I use ChiTuBox and these are my print settings

I do about a 10-15% mix with Anycubic Grey and these are my last print results

Edit: Forgot to add, I cure my model for about 15 minutes before priming.

I want to see somebody try Siraya Tech Blu. I saw a video where somebody made a 22lr suppressor out of this stuff and it held up fine.

I can drop a 28mm miniature from 10 feet to a concrete floor, and nothing happens to it printed in Sariya Blu. It's legit. And, it's cheap as shit.

https://www.amazon.com/gp/product/B07KSYRW34 You get 1 LITER for $49.99.

Hi. Based on the info I found Blu by Siraya is not really flexible but simply bendable (not brittle). As far as I know bendable parts may not crack, break and shatter but they may also not return to their printed form after being bent too much. And flexible almost always returns to its originasl shape. https://www.youtube.com/watch?time_continue=6&v=jxuinrFVw7o I hope I'm not wrong on this and you get my point.

​

is there a specific reason you mix with ordinary brittle resin?

​

Thanks.

Here are a few other tips. When casting small stuff like this you should use a pressure pot. What that does is, while the resin is curing, the pressure, say 4 bar or 60 psi, will squeeze air bubbles down so small that they can't be seen with the naked eye.

If you want to make a lot of these, like thousands, then a good way to make them is via spin casting.

By the way, why are you making these by casting? Do you have a resin printer? If so there are resins that are strong enough to work, like Siraya Tech's Blu. On the other hand, why can't you buy these premade somewhere?

Typically if a part of a model doesn't print, but later pieces do it's pretty safe to presume it's something to do with supports.

As for hollowing, I'm chasing that dragon myself. I've noticed The hollowing function will cause "artifacts" that show up on the first layer of the print when it's sliced and previewed, and they ruin the model. I've had some success with MeshMixer, but the last model I tried to hollow wound up with cracks in the base, so I stopped until I can spend more time researching how to fix them.

Resins - people are using a lot of Elegoo brand resin for their minis. A lot of positive buzz surrounds the Siraya Tech Blu resin, but be aware it needs to print in a warmer environment, 25C or warmer. I have used the sample translucent green to good effect, and I'm working through a bottle of Anycubic white that is similarly working quite well. I've got some of the Elegoo gray and Anycubic plant-based resins sitting in my workspace that haven't been opened yet. I have high hopes for the elegoo and no idea on how the plant-based resin will do.

No idea if anyone makes an auto-refiller for these printers. Good idea though.

My favorite reason lately is Siraya Blu: Blu - Strong and Precise High Resolution 3D Printing Resin by Siraya (1kg) https://www.amazon.com/dp/B07KSYRW34/ref=cm_sw_r_cp_apa_i_FcsjDbDWXH7G7

It's my first time with a resin that's able to make end-use parts like this so it's a lot of fun.
