The Virtual Foundry, LLC, Stoughton, Wisconsin, USA, has released the Filamet™ FFF Metal Evaluation Kit, which provides the materials customers need to additively manufacture, debind and sinter a pure metal part in order to evaluate a filament for their needs. The kit is used for Fused Filament Fabrication (FFF) Additive Manufacturing, a Material Extrusion (MEX) process, and can be processed by standard FFF machines.

Those without a filament-based Additive Manufacturing machine can use a handheld Additive Manufacturing pen to carry out the evaluation; a programmable furnace capable of reaching 1,100ºC is needed for sintering, but, if one isn’t readily available, the green part can be sent to the Virtual Foundry for sintering. Sintering is free for anyone in the continental US and, internationally, costs only the value of return shipping for the sintered part.

The Filamet FFF Metal Evaluation Kit includes:

  • Sample of Bronze Filamet
  • Bag of Sintering Refractory Ballast – Talc
  • Bag of Sintering Refractory Ballast – Al2O3
  • Sintering carbon
  • Example green part
  • Example debound and sintered additively manufactured part
  • Piece of kiln paper
  • Stainless steel sintering crucible

The evaluation kit includes enough filament to additively manufacture two to three Universal Calibration Rings. The STL file for one of these rings is available via the Virtual Foundry’s website.
