Available Formats:
Spools: 1.75mm and 2.85mm diameters in 0.5kg and 1kg weights
Pellets: 1kg jars

Filament Density:
3.25g/cc – 4.15g/cc

Metal Content:
85.4% ± 1.1 17-4 stainless steel

High Compatibility:
Works with virtually any open-architecture 3D printer—no proprietary hardware or specialized equipment required. Also compatible with 3D printing pens.

Easy Printing Experience:

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

• A Filawarmer is required to print this filament

• 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

Fully Sinterable:
After printing, your part can be fired in a furnace to become 100% metal.

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 can I expect for final sintered density of my parts?
✅ Using the instructions we provide, you can expect around 90–95% density. Instructions for sintering are here: https://thevirtualfoundry.com/debind-sinter/

❓ 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.

❓ Can I just debind my part and not sinter it?
✅ A part that has just been debound does not have structural integrity. Stainless Steel 17-4 parts specifically, can not be handled in their brown state as they will not be able to stay together. This is why there is no repacking step in the debinding and sintering instructions for this material.

❓ How can I make my part shiny straight off the build plate?
✅ If you are looking to polish up a part without going through debinding and sintering, you can sand the part with progressively finer sand paper from 120 to 3000 grit. Then polish with a polishing cloth. For a mirror shine, use a cotton buffing wheel and some Zam polishing compound. More instructions here: https://thevirtualfoundry.com/finishing/
