is an acrylate photopolymer, which requires a different process from a traditional wax schedule. Instead of melting at low temperatures, Castable Resin transitions to a gas. The recommended burnout schedule is designed and tested to allow Castable Resin to transition into a gas gradually. The slow transition reduces the possibility of the investment cracking due to rapid expansion of the printed part.
Some customers have reported success in casting Formlabs Clear Resin. More advanced casting houses familiar with successfully casting photopolymers may want to try this material, which offers high detail, good surface finish, and a faster cure cycle.
