Epoxy tooling board sits in the space between wax and aluminum — dense enough to machine like metal, forgiving enough to shape like a polymer.
Stable under heat, low in porosity, and easy to finish, it’s become a standard across small-batch manufacturing and advanced prototyping.

Formed from high-density epoxy resin, each block is uniform in structure and consistent in behavior. It cuts predictably, holds detail, and resists chipping under both roughing and finishing passes.

For makers and engineers, it’s a bridge material — perfect for testing toolpaths, validating part geometry, or building fixturing before committing to more expensive materials such as aluminum or carbon fiber.
