3DXTech CarbonX PEEK+CF20 20% Carbon-Fiber PEEK for Maximum Stiffness & Stability
Carbon-Fiber Reinforced PEEK Filament
CarbonX™ PEEK+CF20 is a high-performance composite filament — 20% chopped carbon fiber in a Victrex® PEEK matrix — engineered for extreme stiffness, excellent dimensional stability and outstanding chemical resistance at high temperature. It’s a true aerospace- and industrial-grade material for the most demanding end-use parts. Requires a high-temperature all-metal hotend and, ideally, a heated chamber.

Authentic 3DXTech CarbonX PEEK+CF20 — supplied and supported by Rev1 Technologies from Auburn Hills, Michigan. We run an additive and metrology lab and can help you dial in a high-temperature PEEK process. Not a re-labeled substitute.
PEEK, Made Stiffer and More Stable.
PEEK is already one of the highest-performing 3D-printing polymers — strong, heat-resistant and chemically inert. Adding 20% chopped carbon fiber raises stiffness and dimensional stability further and reduces warpage, so parts hold tight tolerances under load and temperature. The result is a filament for functional, end-use components in the most demanding environments.
Stiffness and Stability Where It Matters.
The carbon-fiber reinforcement gives PEEK+CF20 a high stiffness-to-weight ratio and excellent dimensional stability — parts resist creep and hold shape at elevated temperature. It keeps PEEK’s hallmark chemical and solvent resistance, making it suited to harsh chemical and high-heat service.
A High-Temperature, Hardened-Nozzle Material.
PEEK+CF20 prints hot — an extruder capable of 385–415 °C and a bed at 130–150 °C, with a heated chamber strongly recommended for the best crystallinity and layer adhesion. Because carbon fiber is abrasive, use a hardened nozzle, and dry the filament before printing. If you’re standing up a PEEK process, Rev1 can help.
Built for Machines That Run Hot.
This is a material for high-temperature industrial printers — all-metal hot ends, heated chambers and hardened nozzles. On the right machine it produces aerospace- and industrial-grade parts that few polymers can match. Not sure your printer is suited? Ask us before you order.

FAQ
Frequently Asked Questions
What is CarbonX PEEK+CF20?
A high-performance 3D-printing filament made from Victrex® PEEK reinforced with 20% chopped carbon fiber. The carbon fiber boosts stiffness and dimensional stability while keeping PEEK’s chemical resistance and high-temperature performance — a true aerospace- and industrial-grade material.
What printer do I need?
A high-temperature industrial printer: an all-metal hot end capable of 385–415 °C, a bed at 130–150 °C, a hardened nozzle (carbon fiber is abrasive), and ideally a heated chamber. If you’re not sure your machine qualifies, tell us the model and we’ll confirm before you order.
Why the hardened nozzle?
Carbon fiber is abrasive and wears out standard brass nozzles quickly. A hardened steel or ruby nozzle keeps dimensions consistent over the life of the spool.
Do I need to dry it?
Yes — like most high-performance polymers, PEEK+CF20 prints best dry. Dry the filament per 3DXTech’s guidance before printing for the cleanest results.
What is it used for?
Demanding functional and end-use parts — aerospace components, semiconductor and oil-and-gas hardware, high-temperature fixtures and chemically exposed parts — where metal-like stiffness, heat resistance and chemical inertness are required.
Is this genuine 3DXTech?
Yes — genuine 3DXTech, Made in the USA, supplied and supported by Rev1 Technologies from Auburn Hills, Michigan, and held in US stock.
