About Us

Why Choose The Virtual Foundry?

At The Virtual Foundry, we manufacture and distribute Filamet™ — a revolutionary line of 3D printing filament loaded with high percentages of metal, glass, or ceramic particles. Our materials are carefully engineered easily print on any open-architecture 3D printer. The materials are specifically designed for hardware from companies like Bambu Lab, Creality, Prusa, and nearly any other printer that uses filament as it’s feedstock.

Our Process

Affordable and Easy to Use, Here’s How it Works

Print with Any Standard 3D Printer
Filamet™ is metal, glass, and ceramic 3D printing filament that is as easy as printing plastic. It works just like regular PLA filament, so you can use the same affordable 3D printers designed for plastic—no special equipment needed!
Remove the Binder in a Kiln
After printing, place the part in a standard kiln—like the ones used for firing ceramics. The kiln slowly heats the part, burning away the PLA binder and leaving behind a porous metal structure, ready for the final step.
Sinter the Particles Together
Next, increase the kiln temperature to fuse the particles together, transforming the print into a pure metal, glass, or ceramic part. This process densifies the material, creating a final product that is strong, durable, and pure.
