Product Overview


Formlabs Castable Wax Resin
Castable Wax Resin is a 20% wax-filled material for casting that can capture intricate features and offers a smooth surface finish for accurate castings with zero ash content and clean burnout. It is ideal for ultrafine structures in jewelry, as well as highly accurate patterns for casting and pressing dental prosthetics.
Key Specifications


For dental: Castable Wax Resin produces highly accurate patterns for casting and pressing dental prosthetics. Tested at length by dental technicians, 3D printed patterns for copings, substructures, full contour crowns, and removable partial denture frameworks are made easy with Castable Wax Resin. Read our Application Guide to learn the complete workflow and best practices for making 3D printed patterns for casting and pressing on your Formlabs 3D printer.
For jewelry: Castable Wax Resin offers high strength and stiffness, making it capable of printing ultrafine structures. The high green strength ensures excellent shape retention for thin patterns such as wire filigree. For heavier jewelry, we recommend using Castable Wax 40 Resin.

NOTES
Castable Wax Resin does not require post-curing. Allow parts to fully dry before casting. While post-curing Castable Wax parts should not affect castability, post-curing may shrink parts slightly (by less than 1%), which can cause distortion.
