Review on 🔍 ESUN Transparent Washable Photopolymer Materials by John Koch

I really wanted to like this resin. It was recommended to me by several members of the community. I had 2 bottles and both containers only made 6 pieces which should have been used less than 1/2. The resin is so incredibly soft that the coasters print great, but the detail just comes from the coasters. Even printing the pre-supported thumbnails I've printed with several other resins fails 100%. The only way I've been able to get some but intermittent success is to STRONGLY support everything. I would use 6-8 "heavy" supports for quarter size parts and in some cases it would work. This was along with a retract speed of 30 (while other prints were 100). I found that I had to re-cure the resin as the test would show that the correct curing time would still not be correct. All the hollow parts still wouldn't clean and often had to use IPA to fully clean the part before curing, defeating the purpose of this resin at twice the price of what I normally print. I threw away the last 1/4 of my second bottle after the same file, this resin only printed correctly for a few hours before failing 3 times in a row under the same conditions. Just go through and move on to another resin. I ended up with a 90% failure rate, while others like Siryatech and Anycubic have around 5% for me.
