Stainless Steel 17-4 Filamet™ lets you print strong, general-purpose stainless parts on an open-architecture FFF/FDM printer and sinter them into 100% metal. It prints like PLA, but a Filawarmer is required.

Specifications

  • Metal content: 80.0%–85.0% 17-4 stainless steel
  • Filament density: 3.25–4.15 g/cc
  • Formats: 1.75mm and 2.85mm spools, and pellets (pick in the variant selector)
  • Nozzle: 0.6mm hardened steel, standard flow

Printing

  • A Filawarmer is required to print this filament
  • Prints similar to PLA with minimal to no warping
  • Feed the filament straight into the extruder
  • Do not dry it: drying degrades the binder

Sintering setup

Want it all in one box? See the 17-4 Print and Sinter Kit.

Applications

  • Prototyping and functional metal parts
  • Aerospace and automotive research
  • Short runs without tooling or machining

About this product

Will it print on my printer?
Filamet works on nearly all open-architecture FFF/FDM printers. Swap in a hardened steel nozzle (the size is in the specifications above) and print it like PLA. Not sure about your model? Email us the printer name and we'll check before you buy.
Do I need a Filawarmer?
Yes. This filament needs one to print well: it resets the spool memory of the filament as it feeds. The Filawarmer is included in the Print and Sinter kits; if you buy the spool on its own you will need to source one separately.
How is 17-4 different from 316L?
17-4 is a precipitation-hardening stainless that can be heat-treated after sintering for much higher hardness and tensile strength than 316L. Choose 17-4 when mechanical performance matters most, 316L when corrosion resistance does.
What do I need to sinter 17-4?
A kiln that reaches at least 1250C in an inert or reducing atmosphere. The FireX and FireX Max are compatible. Use Steel Blend ballast under Sintering Carbon.
How dense is the sintered part?
Following The Virtual Foundry's debinding and sintering instructions, expect roughly 90-95% density.
