Stainless Steel 17-4 Filamet™ Print and Sinter Kit

Everything you need to print and sinter real 17-4 stainless steel parts—in one kit. The Stainless Steel 17-4 Print and Sinter Kit combines Filamet™ filament with the consumables required for debinding and sintering, so you can go from CAD to precipitation-hardened metal on any open-architecture FDM printer.

Kit Includes:

• 0.5kg or 1.0kg Stainless Steel 17-4 Filamet™ (1.75mm or 2.85mm)

• Filawarmer

• 300mL Alumina Crucible

• 1kg Steel Blend

• 0.5kg Sintering Carbon

Filament Density:
3.25g/cc – 4.15g/cc

Metal Content:
80.0% – 85.0% 17-4 stainless steel

Easy Printing Experience:

• Print with a 0.6mm hardened steel, standard flow nozzle

• Prints similar to PLA

• Minimal to no warping

• Ensure the filament feeds straight into the extruder

• Less hygroscopic than PLA

  • Do not dry this filament—drying will degrade the binder

FAQ:

❓ Can I print this on my printer?
✅ Filamet™ is compatible with nearly all FFF/FDM based 3D printers on the market. Switch out the nozzle for a 0.6mm hardened steel nozzle and get printing! The list of printers that have been used and the ones that are not compatible can be found here: https://thevirtualfoundry.com/trusted-printers/

❓ What sintering equipment do I need?
✅ You need a kiln capable of reaching at least 1250°C in an inert or reducing atmosphere. The TVF Sintering Kiln, FireX, and FireX Max are all compatible with Stainless Steel 17-4. See our debind and sinter instructions for full profiles.

❓ What makes 17-4 different from 316L?
✅ Stainless Steel 17-4 is a precipitation-hardening stainless steel that can be heat-treated after sintering to achieve significantly higher hardness and tensile strength than 316L. It's the preferred choice when mechanical performance is the priority over corrosion resistance.

❓ How strong are parts right off the printer?
✅ They are quite a bit stronger than you may expect. You can throw them around a little and handle them just fine. Generally, they will not handle load nearly as well as the base PLA would on its own.
