UV Photopolymer Resins
It has been a moment since I last logged into this site...So welcome back to me.... I have been working with 3d printed resins now for a minute. Had a lot of mixed results and learned some tricks. 1st off, I have noticed that the "wax" resins don't reproduce fine detail and are generally better for heavy parts like thick shank men's rings. I have only cast a few rings from one companies "cast-able wax resin" I can say that I'm not impressed though it does work for some things. It is interesting that they are combining polyethylene and acrylate based materials. All of the resins seem to be very hygroscopic and or susceptible to the moisture or lack of it in the air. Like lets post cure the resin in glycerin to keep the air away.So environmental variables are a big factor in getting good prints. Going back to the hygroscopic issue... us casters want to take an object and put in a mixture of WATER and investment could be acid binding gypsum based or phosp...
