Be very careful with that! I found the one you bought (I'm assuming it's this one). It's laboratory grade, which means it likely isn't inhibited with something like BHT. It will form extremely explosive peroxides in air. I very much recommend you to buy a stabilizer to add to that THF.
If anyone else is looking to buy THF, be absolutely, 100% sure that it is stabilized.
Well what i was planning, is to make the cup on the inside as super smooth as possible using sanding and a heat gun. Also maybe acetone if I use PETG (not sure if that works or not).
I have a really strong chemical,
Tetrahydrofuran, it supposedly smooths PLA. I havent tried it because I am a little afraid of it...I want to be 100% certain that any gloves I wear it wont simply leech through.
I'm not saying that shellac wont work, and it is certainly food safe. I just suspect it has a low melting point. I mean it's used for the hard shell on some types of candy, and those shells certainly do melt. It's called confectioners glaze. Maybe they use a very thin coating?
There has to be some kind of coating out there, I just don't know what it is.
The alternative is to use the 3D printed object to make a mold for ceramic mugs, but that's too old school for me and this sub.

You don't really need boric Acid, you can just use THF. Also, this chemical is EXTREMELY DANGEROUS. Be careful and use lab safety equipment. Do this on your risk.
For PLA if you're not adverse to working with chlorinated solvents, Methylene Chloride or Tetrahydrofuran will work. There are some varieties of PLA that have higher amounts of PHA or other things in them that will let them be slightly smoothed with acetone though.
XTC-3D epoxy coating is generally easier and miles safer to work with.
I don't doubt it's more difficult, but it looks like you can get some right off Amazon. Since you seem to know what's up, if someone got some, could they use it several times if they get themselves something they can seal up after bathing the part, or is it more of a one time use sort of thing?
