Create real ceramic 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 (0.25kg and 0.5kg)
    • Pellets: 1kg jars
  • Filament Density: 1.30g/cc – 1.50g/cc
  • Ceramic Content: 50.0% – 60.0% Boron Carbide

Special Qualities: Neutron Absorption

Boron Carbide is one of the hardest materials known, but its most notable property in 3D printing is its ability to absorb neutrons. This filament can be used for neutron shielding applications with no sintering required to achieve its absorption properties.

Printing Experience

  • Print with a 0.6mm hardened steel nozzle.
  • Prints similar to PLA with minimal to no warping.
  • Works with virtually any open-architecture 3D printer (no proprietary hardware required).
  • Ensure the filament feeds straight into the extruder.
  • Important: Less hygroscopic than PLA. Do not dry this filament—drying will degrade the binder.

Applications

  • Neutron Absorption and Shielding
  • Nuclear and Physics Research
  • Functional prototyping for high-hardness components
  • 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. Large orders may be subject to longer lead times.
