Review on ESUN 405Nm LCD 3D Printer Rapid Resin UV Curing Resin ABS-Like Rapid Resin Hard Tough Resin High Impact High Tough Photopolymer Resin For Photon UV Curing LCD 3D Printer by John Ghattamaraju

With this resin I get beautiful, very accurate prints. I can see some shrinkage, if any, and the parts seem flexible even after the test I do when I repeat the supports. I've noticed some clumps of pigment in the resin, but they don't seem to have affected my prints so far. I wish the gray was a little darker, but that's a matter of taste. The smell is definitely more smelly. But I would still recommend installing activated carbon filters on your printer. I have attached my printing profile for Elegoo Mars 2. This is a direct copy of the EPAX Hard profile, which I've had nothing but success with. Update: I spoke too soon I think. One of my most recent prints has a cosmetic and physical defect due to one of the age spots. I continue to use this resin with more of a focus on age spot removal, but eSun should definitely fix that. Update 2: I have noticed that after a few days this resin becomes quite brittle like the others. Avantek Eupheng's high strength resin is the only resin I've tested that doesn't become brittle after a while, but unfortunately it's not currently available.
