Through a few month's experiments, we finally made 3d casting resin that is with 90% wax which is called ultra-cast, it is able to work on DLP or LCD 3d printer with oxygen machine, if your printer is without oxygen machine, don't worry, the special film comes with makes it able to work on your 3d printer with high successfully printing rate, and if your printer is bigger size, take 1kg as it is with A4 size film.
Ultra cast is good for jewelry silver gold casting or dental ceramic cast, as jamghe resin always focus on high precision, and no expanded during the burn out process, so the size is exactly right after casting.
