Stainless Steel 316L Filamet™ prints corrosion-resistant stainless parts on an open-architecture FFF/FDM printer and sinters them into 100% metal. It prints like PLA, but a Filawarmer is required.

Specifications

Metal content: 80.0%–85.0% 316L stainless steel
Filament density: 3.45–3.55 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

Ballast: Steel Blend, covered with Sintering Carbon (optional Kiln Paper)
Crucible: Alumina
Kiln: FireX or FireX Max

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.

When should I choose 316L?

Choose 316L when corrosion resistance is the priority. If you need higher hardness and strength, look at 17-4, which can be heat-treated after sintering.

What do I need to sinter 316L?

A kiln listed as compatible with stainless steel, such as the FireX or FireX Max, plus Steel Blend ballast, Sintering Carbon and an alumina or refractory cement crucible.

How dense is the sintered part?

Following The Virtual Foundry's debinding and sintering instructions, expect roughly 90-95% density.
