Review on ELEGOO Water Washable 3D Printer Resin LCD UV-Curing Resin 405Nm Standard Photopolymer Resin For LCD 3D Printing 1000Gram Black by Andy Baudoin

I've had great success with this resin. There are no problems with hacking and other things. In my experience, correct printer settings and support ensure no problems. As far as sustainability is concerned, I don't think that's 100% fair. Their own Safety Data Sheet report contains the following that you should definitely read and follow, but TL'DR says it at the end: 6.2 Environmental Precautions: Do not allow product to enter drains or water sources. Do not allow to enter drains/surface. or ground water Section 12: Ecological information. Literally all of the information in this section is basically labeled "No information available" but then you get to Section 12.7 and find out that it's toxic to aquatic life. Section 13: Disposal considerations Disposal must be made in accordance with official regulations. AKA contact your local waste disposal service to dispose of excess AND items you've washed and hopefully kept in a bin and not just washed down the drain. So TL; DR great resin, make sure you properly flush and dispose of leftover dish soap particles according to local laws and regulations. No seriously, unless you need water like in Flint Michigan, do it.
