Copper Filamet™

Create real metal parts using any open-architecture FFF/FDM 3D printer—or even a 3D printing pen.

Available Formats:
Spools: 1.75mm and 2.85mm diameters in 0.5kg, 1kg, and 3kg weights
Pellets: 1kg and 3kg units

Filament Density:
4.3g/cc - 5.0g/cc

Metal Content:
86.0% – 90.7% copper

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

• 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 integrety. Copper parts specifically, can be handled gently, but you must be careful.

❓ 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 progressivly 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/
