Sand Castings in Just a Few Hours

The Robotic Additive Manufacturing systems from EnvisionTEC and Viridis3D are the fastest, most flexible robotic 3D printing options in the foundry and 3D printing industries today.

Using a patent-pending technology, a proprietary print head attached to an ABB robot arm uses exclusive binder jetting technology to print sand molds, mold cores and investment casting patterns for foundry applications. The proprietary systems include easy-to-use Viriprint software that uses a CAD file to print a mold and core in just a few hours.
