Formlabs True Cast Resin is an SLA 3D printing material engineered specifically for direct investment casting applications. Formulated to burn out cleanly in kiln firing with near-zero ash residue, True Cast patterns produce metal castings with fine surface detail and dimensional accuracy comparable to traditionally wax-injected patterns - enabling faster, more flexible casting workflows without tooling costs.

True Cast Resin is the preferred choice for jewellery designers, dental technicians and industrial foundries who need to produce casting patterns from digital designs. It supports both traditional investment casting with gypsum or phosphate investments and direct casting setups, and its clean burnout profile eliminates the porosity and surface defects that less-optimised resins can leave in the mould cavity. Available in a 0.5kg cartridge suitable for the Form 3 and Form 3L.
