Wear Gloves. Returning is impossible Resin does not just harden, it polymerizes into shape from monomers in a chemical reaction. That means to break it down, you need to destroy the whole chemistry. There is no solvent that can simply reverse it. Wiping is easy As long as the rein is still liquid, you can wipe it off. Then clean the parts with Isopropylic ...

Rejuvenate is probably a bit of an exaggerated term. The number one adhesion suppressor is grease. The stuff that comes off of the fingers used to handle the sheet. Even if you are careful and only handle the sides, the grease will be carried to the center of the plate next time its cleaned with less aggressive solvents. Isopropyl alchohol does break down ...

Concentrated nitric acid will remove all organics, including your skin, wire insulation, etc. It will work on a glass plate, but the fumes would eventually damage the plastics on your printer unless you remove the glass plate to clean it. Nitric acid will destroy most build surfaces that are added to glass. To a lesser extent concentrated sulfuric acid ...

Most commercial blow-molded fuel tanks for model airplane fuel (methanol or ethanol, nitromethane or nitroethane, and some combination of castor, mineral, or synthetic lubricating oil) are made from HDPE. This material isn't commonly seen as filament, in my limited experience, but it ought to be possible to arrive at settings that will give a liquid tight ...

As a supplement to the answer (doesn't fit well in the comments). This site https://www.filamentive.com/chemical-resistance-of-3d-printing-filament/ lists PETG has have a very high restance to alcohol, a high resitance to fuel Is PETG UV Resistant? In the long run, it is now a well-known fact that it will almost always come out on top when it comes to ...

I would try hexane, and then Dichloromethane and if those did not work, I would heat up sodium hydroxide to about 70-90 °C. These would work better if you print in PLA resin, it's available from a few sources now. Bucktown polymers and 3Dresyns both have a water-soluble resin. You could also print, make a soft silicone mold, cast in chocolate or isomalt and ...
