KeyPrint® KeyCast®


KeyPrint® KeyCast®

Perfect for ash-free investment casting

Keystone Industries KeyCast® is a light-curing 3D printing resin designed for residue-free and precise dental castings. It is compatible with a variety of investment materials for clean burnout using rapid or gradual temperature ramping, such as removable partial denture frames, crowns, bridges and copings.

Residue-Free for Precise Dental Castings

The KeyPrint® KeyCast light-curing 3D printing resin was designed for quick, accurate, and residue-free dental castings. The low-shrinkage formula controls thermal expansion to yield porous-free and precise castings. It is compatible with rapid burnout and gradual temperature ramp workflows, with no residual ash.

KeyCast can be used with metals such as chrome cobalt, gold, and silver.
