Carbon fiber and Nylon 12, engineered to print stable.
CarbonX™ Nylon 12+CF combines high-modulus chopped carbon fiber with a specialty PA12 that 3DXTech chose for printability, thermal performance, and chemical resistance. The carbon reinforcement stiffens the part and, just as importantly, suppresses shrinkage — so prints come off the bed dimensionally stable and repeatable part-to-part. That makes it a go-to for tooling, fixtures, and jigs that have to hold a measurement, while PA12’s naturally low moisture absorption keeps it far easier to run than PA6-based nylons.
Print functional parts that hold their shape.
Low shrink and high stiffness turn your CAD directly into a dimensionally stable component.
3DXTech’s formulation is tuned for very low shrinkage in the printed part, which is what gives PA12+CF its excellent dimensional stability. Combined with high stiffness and a wide processing window, it’s an ideal material for tools, fixtures, and jigs — parts where the printed geometry has to match the model and stay that way across a production run.
Stiffness and strength, straight from the datasheet.
Every figure below is published on the 3DXTech CarbonX Nylon 12+CF technical data sheet (Rev 1.0, ISO test methods). See the full TDS for test conditions and specimen orientation.
Carbon-fiber stiffness (ISO 527) — parts resist deflection under sustained mechanical load.
Strength at break (ISO 527), well-matched to structural tooling and fixture duty.
High bending stiffness (ISO 178) for brackets, mounts, and load-bearing geometry.
Bending strength (ISO 178) that holds up in cantilevered and clamped fixtures.
Low elongation (ISO 527) typical of a stiff, fiber-filled composite — rigid, not rubbery.
Lightweight parts (ISO 1183) — strength and stiffness without the weight of metal.
A forgiving window — with a hardened nozzle.
These are 3DXTech’s recommended print settings. Carbon fiber is abrasive, so a hardened steel nozzle is a must; nylon absorbs moisture, so dry it first. PA12 takes on far less water than PA6, which makes it more consistent to run.
A wide, forgiving hotend window — start mid-range and tune for your printer and speed.
A heated bed with a suitable adhesive for reliable first-layer grip on nylon.
Not required, but an enclosed, heated chamber helps the biggest parts stay flat and true.
Use a hardened-steel or abrasion-resistant nozzle — carbon fiber wears out brass fast.
Run 0.25 mm or thicker layers for the best strength and consistent flow with the filled filament.
Dry the filament and keep it dry for the best surface finish and layer adhesion.
The parts engineers print in PA12+CF.
Because it’s stiff, dimensionally stable, chemically resistant, and heat-tolerant, CarbonX Nylon 12+CF is a go-to for parts that actually go into service — not just prototypes.
Matte carbon-fiber black — with a spec on every reel.
CarbonX Nylon 12+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 750 g and 2 kg reels; choose your reel size in the buy-box, or ask us about bulk and standing-order pricing.
Diameter, grade, and print temps — right on the spool.
No mystery filament: the reel carries its identity so anyone at the printer can confirm settings.
Each CarbonX Nylon 12+CF reel is labelled “PA12+CF — Carbon Fiber Reinforced Nylon 12,” with the 1.75 mm diameter and the recommended extruder (265–285°C) and bed (90–110°C) temperatures printed right on the spool. It ships from Rev1 with a published TDS and lot traceability so you always know exactly what’s loaded.

FAQ
3DXTech CarbonX Nylon 12+CF — Common Questions
What is CarbonX Nylon 12+CF?
It’s a carbon-fiber reinforced Nylon 12 (PA12+CF) filament from 3DXTech. High-modulus chopped carbon fiber in a specialty PA12 gives stiff, dimensionally stable parts with low warp, low moisture absorption, and strong chemical resistance — ideal for tools, fixtures, jigs, and functional end-use parts.
Do I need a special nozzle?
Yes — because it’s carbon-fiber filled, the fiber is abrasive and will wear a soft brass nozzle. Use a hardened steel nozzle (0.4 mm minimum). Hardened nozzles are inexpensive and easy to install.
What temperatures does it print at?
Extruder 265–285°C and bed 90–110°C, with 0.25 mm or larger layers. A heated chamber is recommended for the largest, most dimensionally stable parts. Dry the filament at 90°C for four hours before printing.
How is PA12+CF different from PA6+CF?
PA12 absorbs far less moisture than PA6, so it prints more consistently and holds its properties better in humid conditions. It also offers superior chemical resistance. Both are stiff carbon-filled nylons; PA12+CF trades a little peak strength for much easier, more stable printing. Start with the 750 g reel to qualify your profile; the 2 kg reel is a special-order production size (MOQ applies).
Is it electrically conductive or ESD-safe?
No. CarbonX Nylon 12+CF is a structural carbon-fiber grade with a high surface resistance (>10⁸ Ohm/sq), so it behaves as an insulator, not an ESD-safe material. If you need static dissipation, ask Rev1 about 3DXTech’s dedicated ESD-safe grades.
Is it made in the USA?
Yes — 3DXTech manufactures CarbonX Nylon 12+CF in its ISO 9001:2015-certified facility in Grand Rapids, Michigan, with a published TDS and SDS and lot traceability. Tell us the part, the loads, and the environment and our materials team can confirm fit and even run a sample print.
