Create real metal parts using any open-architecture FFF/FDM 3D printer—or even a 3D printing pen.
Product Specifications
Available Formats:
Spools: 1.75mm and 2.85mm (0.5kg, 1kg, 3kg, and 5kg)
Pellets: 1kg, 3kg, and 5kg units
Filament Density: 7.80g/cc – 9.20g/cc
Metal Content: 88.0% – 94.0% pure tungsten
Printing & Compatibility
Works with virtually any open-architecture 3D printer—no proprietary hardware or specialized equipment required. Also compatible with 3D printing pens.
Print with a 0.6mm hardened steel nozzle.
Prints similar to PLA with minimal to no warping.
Ensure the filament feeds straight into the extruder.
Important: Less hygroscopic than PLA. Do not dry this filament—drying will degrade the binder.
👉 Calibration: Print
this test model
to ensure you're getting the highest density. The model should weigh 5.5g or more.
Special Qualities & Applications
Can be used as a replacement for lead for radiation shielding with no sintering required.
Radiation shielding
Scientific Research
One-off and short-run manufacturing
Reducing or eliminating tooling and machining costs
All formats print just like PLA on most open-architecture 3D printers.
