3DXTECH's CarbonX PEI 3D Printing Filament brings industrial strength to 3D printed parts

3DXTECH’s CarbonX PEI 3D printing filament will perform in the most extreme applications because it is inherently flame retardant, resists absorption of atmospheric moisture, and possess a stable dielectric constant to dissipate a wide range of frequencies. This makes 3DXTECH’s CarbonX PEI 3D printing filament ideal for your toughest automotive and electronics parts and projects.

The CarbonX series of 3D printing filaments from 3DXTECH brings enhanced properties to the 3D printing materials you already know and love. The high-modulus carbon fiber fill used in CarbonX 3D printing filament is stronger than steel and delivers boosted stiffness, dimensional stability, and UV-resistance to your 3D printed parts. Additionally, finished parts 3D printed with CarbonX filament are more lightweight, and have a nice matte black appearance.
