3DXTech CarbonX PP+CF Carbon-Fiber Polypropylene — Ultra-Light, Chemically Resistant, USA-Made
Carbon-Fiber Polypropylene — Ultra-Light, Chemically Resistant, USA-Made
A USA-made polypropylene copolymer reinforced with high-modulus chopped carbon fiber — a patent-pending formulation with improved thermal properties and low shrinkage/warp versus competitive PP compounds. Print exceptionally light, stiff, chemically resistant parts for medical, drone, marine, and automotive work. Because PP+CF is so low-density, a 750 g reel holds about the same length as a 1 kg reel of ABS. Full specifications →

Featherweight and rigid — parts that shrug off chemicals.
CarbonX PP+CF is a specialty polypropylene copolymer reinforced with high-modulus chopped carbon fiber, built on a patent-pending formulation that improves thermal performance and cuts the shrinkage and warp that plague ordinary PP. The result is a filament that prints on practically any 3D printer yet delivers a stiff, chemically resistant, exceptionally light end-use part. Because PP+CF is so low-density, a 750 g reel holds roughly the same length of filament as a 1 kg reel of ABS. 3DXTech compounds it in the USA for medical, drone, marine, and automotive components.
High stiffness at the lowest density in the CarbonX line.
Carbon-fiber reinforcement, tuned to print easy.
Polypropylene is one of the lightest thermoplastics available, and carbon-fiber reinforcement lifts its tensile modulus to 6150 MPa — so you get rigid, load-bearing parts that weigh far less than the same part in ABS or nylon. The patent-pending compound also tames PP's notorious warp, and a matte carbon-fiber-black finish comes straight off the plate. Excellent chemical resistance to acids, bases, and solvents makes it a go-to for parts exposed to fuels, cleaners, and marine environments.
Stiffness, chemical resistance, and almost no weight.
CarbonX PP+CF is built for light, structural, chemically-exposed parts. Numbers below are from the published TDS (Rev 1.0, ISO-tested).
High-modulus carbon fiber (ISO 527) — rigid parts at polypropylene's featherweight density.
Strong at break (ISO 527) — holds up under sustained structural load.
Stiff in bending (ISO 178) with a 68 MPa flexural strength — rigid, not floppy.
Among the lightest engineering filaments (ISO 1183) — a 750 g reel prints like 1 kg of ABS.
Deflection temp at 0.45 MPa (ISO 75) — higher-temp tolerance than commodity PP.
Resists acids, bases, and solvents (acetone, ethanol, MEK) — and absorbs no moisture.
Easy to run — just mind the bed adhesion.
These are 3DXTech's recommended print settings. PP+CF prints on practically any printer and needs no drying — the one thing to plan for is bed adhesion, since polypropylene bonds to very little.
Runs at 220–250°C on most printers, up to 270°C on some — no exotic high-temp hotend required.
Prints from room-temp to a warm bed; TDS specimens ran at 85°C. Not fussy about heat.
Use PP-based packaging tape or a polypropylene build sheet — PP bonds best to itself.
Use a hardened-steel or abrasion-resistant nozzle — carbon fiber wears out brass fast.
Target 60% of nozzle diameter; do not run below 0.25 mm with carbon-fiber grades.
Polypropylene doesn't absorb water — no drybox, no oven, just open and print.
Built for light, structural, chemically-exposed parts.
From CAD to a lightweight, chemically-resistant part that ships.
Print drone frames, marine hardware, jigs, and end-use components.
Because it's rigid, ultra-light, and shrugs off chemicals and moisture, CarbonX PP+CF lands in parts that actually go into service. Low weight matters for drones and watercraft; chemical resistance matters for automotive and industrial fluids; and zero moisture uptake means parts stay dimensionally stable in the field.
Matte carbon-fiber black — the only color it comes in.
CarbonX PP+CF ships in a single, purpose-built color: a deep matte carbon-fiber black. Carbon fiber is inherently black — there are no other color options for this material. It's available in 1.75 mm on 650 g and 1.7 kg reels; choose your reel size in the buy-box, or ask us about 2.85 mm, bulk, and standing-order pricing.
Check the reel fits your printer.
Standard spool dimensions — confirm it fits your AMS or dry box.
3DXTech ships CarbonX on consistent, standard reels.
Before you buy, check the outer diameter, width, and center bore against your printer's spool holder, automated material system, or drybox. The 650 g reel fits popular AMS systems (Bambu AMS, Creality CFS, Anycubic ACE Pro). Open the full 3DXTech reel infographic for exact dimensions.

FAQ
3DXTech CarbonX PP+CF — Common Questions
Do I need a special printer?
No — CarbonX PP+CF prints at 240–270°C on practically any 3D printer, with no heated chamber required. You do need a hardened-steel nozzle because the carbon fiber is abrasive, and you'll want the right bed surface for adhesion.
Why won't it stick to my bed?
Polypropylene bonds to very little except itself. Use PP-based packaging tape or a polypropylene build sheet on the bed for reliable first-layer adhesion — standard glue and PEI don't grip PP well.
Do I have to dry it?
No. Unlike nylon, polypropylene does not absorb moisture from the air, so there's no drying step — just open the reel and print. That's one of PP+CF's big advantages.
Why do I need a hardened nozzle?
The carbon fiber that gives this filament its rigidity is abrasive and will quickly wear out a standard brass nozzle. Use a hardened-steel or other abrasion-resistant nozzle, 0.4 mm minimum.
How is it different from CarbonX PETG+CF or nylon?
All are carbon-fiber reinforced. PP+CF is the lightest and most chemically resistant, absorbs no moisture, and prints on any printer — but needs special bed prep. PETG+CF is easy and stiff; nylon CF is the stiffest and highest-heat but must be kept dry. We'll help you choose.
Is it made in the USA?
Yes — 3DXTech manufactures CarbonX PP+CF at its 68,000 sq ft facility in Grand Rapids, Michigan, with a published data sheet and lot traceability.
