Trusted Seller
The Virtual Foundry is the only company offering sinterable, high metal-content 3D printing filaments that run on any standard FFF/FDM 3D printer with no specialized equipment needed. Our Filamet™ line allows makers, educators, and researchers 3D print real metal, glass, or ceramic parts that can be debound and sintered to create pure metal parts with high density. This unique open-platform approach makes metal additive manufacturing more accessible, flexible, and affordable, unlocking advanced applications with the printers you already own.

FAQs
What printers work with Filamet™?
There is a long list of printers that work with Filamet™. If it can print PLA from any brand, and there are hardened steel 0.6mm nozzles available for the printer, then it can print Filamet™. This includes the Bambu Lab X1 Carbon!
Does Filamet™ need to be dried?
No, in fact it is harmful to the filament. Filament drying is done with heat and if Filamet™ is heated, it becomes more pliable, but once cooled, it becomes extremely brittle and may even shatter. The reason the Filawarmer works is the filament is not heated for a long period of time and the heat is applied to a small section as it is being printed.
What is the expected shrinkage?
Expected shrinkage with the instructions on our website is 7 - 10% for bronze and copper, 10% for stainless steel (17-4 & 316L), Inconel 718, and M300, and 25% for Pyrex.
Why is sintering untested on Aluminum and Titanium?
We focus on developing cutting-edge 3D printing materials. A few of our materials are untested. Aluminum and Titanium are untested because sintering them requires conditions that we are not able to achieve with our equipment. Both of these metals are reactive at higher temperatures, quickly oxidizing, causing the particles to fail to bond.
How strong are green parts?
Stronger than you may think. The actual strength is highly geometry dependent. You can drop most parts on the floor and at most, they may dent a little. The Universal Calibration Rings have been tossed 10-15 feet onto concrete floors and they barely scuff. The smokestack on the 3D Benchy, however, would break off.
