I just find that it is very expensive, doesn’t store well, degrades or separates in the tank far too quickly, and has a low success rate for anything larger than jewelry. The other resins have made the machine worth it though. I plan to use it to make injection molds for waxes in the future (maybe)
I found that it doesn’t store well in the tank. After a few prints the resin starts to develop white flakes and prints will fail at every attempt. if the print succeeds then I will have trouble post curing and then casting. ( i have tried to stir it into the resin again but it wasn’t having it.) It’s also very expensive for a product I have yet to have a successful print-to-cast experience with. Burnout isn’t particularly clean either.
Recently I gave it another try for a project. I used my own orientation and had poor print results (the flat areas near the build plate went to hell and were sloppy. A second attempt was made with Formlabs recommended support and orientation. the geometry was alright but there were peel issues where there were harsh lines across the print in some areas and the supports seemed to have pulled away from the main areas and taken shards from the printed shapes. The printer is quite amazing but the castable resin is sub par for my purposes unfortunately.
