The Virtual Foundry

The Virtual Foundry manufactures and sells Filamet, a 3D printing filament loaded with high percentages of metal, glass, or ceramic particles. The filament prints on standard open-architecture 3D printers, and parts are then debound and sintered in a kiln to leave a solid metal, glass, or ceramic piece. The company also sells Rapid 3DShield, a high-density tungsten filament for radiation shielding, counterweights and other dense parts, and offers a metal 3D printing curriculum for schools and training programs.

Customers can order online through the company's shop, and the team also takes custom requests to make filament from a specific material. The company is based on US Highway 51 in Stoughton, Wisconsin, and has been in business for more than ten years.
