Formlabs Castable Wax Resin

Castable Wax resin is an SLA 3D printing photopolymer designed for direct investment casting and custom try-ons. Manufactured by Formlabs, it can be used by jewelry designers, dental professionals and engineers for the production of intricate shapes, complex geometries and detailed surfaces. It delivers polished finishes and neat edges.

Castable Wax Resin is an acrylate polymer composed of 20% liquid wax. It enables simple and clean casting free from ash or other residues. It is used to produce high-precision, intricate models with hairlike details as well as dental crowns and bridges. All products printed with the wax-filled resin are robust enough to handle. They require minimal finishing and no post-cure streamlining the casting process. Continue reading our thorough review.

Resin features

Castable Wax Resin produces easy-to-handle, high-strength models that don’t require post-cure. It supports print at 50 and 25 microns. Set the layer height at 50 microns to print in short times while achieving clinically acceptable accuracy. Using a Resin Tank LT is strongly suggested.

Castable Wax is packed into 1L cartridges.

For successful casting, it is important to take into consideration both the design of the piece and the properties of the material. Formlabs provides accurate setup instructions and print settings for generating a correct print model in PreForm. Also, it offers a complete usage guide that contains all the necessary investment instructions, recommendations, settings, and burnout schedules.
