The Virtual Foundry is currently selling SS316L, 17-4, Copper, Bronze, Aluminum Oxide, Zirconium Silicate, High Carbon Iron and Tungsten filaments. Their “open architecture” means that print size is limited only by the size of the printing and sintering equipment that can be sourced on the open market.

The Virtual Foundry metal filaments enable any Fused Deposition Modeling or Fused Filament Fabrication (FFF) 3D printer to produce metal objects at a fraction of the cost.

The need to move ideas ever more quickly through systems (fail fast) and always with an eye toward economy (fail cheap) leads to a necessity for easy metal parts. The use of metal filaments in FFF desktop and large-scale printers offers advantages that other, more established applications just can't match. Safety, cost and ease-of-entry are all important considerations when deciding which technology to pursue.

Once these 3D printed objects are fired in a sintering furnace or high capacity kiln, the result is 100% pure metal.
