FormLabs Resin Castable Wax
High precision direct casting resin – 20% wax, zero residue
Formlabs Castable Wax Resin is a professional-grade resin designed for no-post-curing investment casting , ideal for jewelry, dentistry, and investment casting applications. Its formulation contains 20% real wax , ensuring a clean burnout with no residual ash and maintaining excellent precision in the most intricate details.
It is the ideal solution for those who want to print casting-ready models with sharp details, smooth surfaces and complex geometries, such as watermarks or thin supports.
Castable Wax Resin is compatible with standard and rapid burning cycles. It is recommended to use specific lost wax or high heat resistance plasters. It does not require any post-curing: after washing, the models are ready to be included directly in the cylinders.
