CarbonX Carbon-fiber Reinforced Polycarbonate Filament, known as CF-PC, is a fantastic carbon-filled printing material that not only delivers great structural integrity at a high heat, softness, and with excellent surface quality.

Polycarbonate is used EVERYWHERE -- there’s probably some within reach of you, as you’re watching this video: Electronic components, as a good insulator while being heat-resistant and flame-retardant; construction materials, like dome lights, glazing, roofing sheets, sound walls; In data storage, all those CD’s, DVD’s, and Blu-Rays are made of polycarbonate… in sheets/films, it’s used for signs, displays, and posters. Carbon fiber polycarbonate is often seen in the automotive industry because of its thermal properties, in manufacturing for tooling and jigs, and in aerospace for tubing.


Nozzle Temp: 280-310°C
Bed Temp: 110 - 120°C - for adhesive, our Nano Polymer Adhesive works great!
Chamber Temp: You don’t HAVE to have a heated chamber, but on anything bigger than a few inches, it sure helps a LOT.

If you’re dual-extruding, this stuff works great with Aquatek X1 support filament, also from 3DXTech!

For bed adhesion, our nano polymer adhesive works GREAT on every surface we’ve tested! One bottle to rule them all…. Seriously, our stuff works with just about every material aside from POM and PP, so grab a bottle if you haven’t already!
Speed: again, 40-80mm/s and faster -- on the HSE, they’re printing this stuff at 50-500 mm/s -- that’s right --- the HSE is an incredible machine, make sure you look that up.
Chamber Temp: Not required, but 60+c is helpful for strength!

Drying: yes, you MUST dry this filament. Like almost every thermoplastic, this does need to be dried thoroughly before processing, which is the fancy word for melting.

We do have a full drying kit, including the vacuum chamber, at -- it’s the best way we’ve found to get all that moisture out, so your prints don’t get ugly and weak. We’re here to make it easy, and that’s why we ALSO made METAL spools, so you can dry at higher temps, faster. With Nylon, a vacuum chamber helps a TON, so definitely check those out.


The addition of Carbon Fiber in PC increases flexural and tensile strengths, making material more rigid when printed. Without Carbon Fiber, the known specs for strength in polycarbonate filaments are:

Tensile Strength: 95MPa
Tensile Elongation: 60% at Break
Tensile Modulus: 320MPa
Flexural Strength: 15MPa

While measurements on CarbonX CF+PC are not readily available, you can assume the addition of CF adds to these measurements for normal PC by 3DxTech.

Environmental Factors

UV: Not the greatest, as Polycarbonate does break down over time, with direct exposure to sunlight.

Hydrolytic resistance
Absorbs water very fast normally, will absorb water less so after printing

Food contact for CF-filled items is not recommended
Oil & hydrocarbons
Great resistance to greases, lubricants, and oils
Alcohols: Good (Methyl, Ethyl, Benzyl, Butyl)
Acetone: Vulnerable
Chlorine: Fair Resistance
Sulfuric Acid & HCL: Vulnerable
3.17 Dielectric Constant at 60Hz
10^16 Ohm Resistance
Carbon Fiber will negatively impact PC’s insulative properties
