3DXTech CarbonX HTN+CF Carbon-Fiber High-Temp Nylon (PA-HT) — 200°C Heat Deflection, Prints Without a Heated Chamber
Carbon-Fiber High-Temp Nylon (PA-HT) — 200°C Heat Deflection, Prints Without a Heated Chamber
A USA-made high-temperature nylon (HTN / PA-HT) reinforced with high-modulus carbon fiber — engineered for heat-resistant, load-bearing parts that other grades of nylon can't handle. It delivers a 200°C heat-deflection temperature and a 150°C continuous service rating, yet prints on a standard high-flow hotend at around 295°C with low warp and no heated chamber required.

USA-made high-temp carbon-fiber nylon, with a real datasheet behind it.
3DXTech compounds CarbonX HTN+CF in Grand Rapids, Michigan at its 68,000 sq ft facility, with independent third-party-lab print and material data — no mystery filament. Rev1 Technologies is your authorized 3DXTech reseller and US support partner, Auburn Hills, Michigan.
Heat resistance other nylons can't reach — without the exotic printer.
CarbonX HTN+CF is a high-temperature nylon (HTN / PA-HT) reinforced with high-modulus carbon fiber. It's the pick when a part has to survive real heat — a 200°C heat-deflection temperature and a 150°C continuous service rating — while staying stiff, chemically resistant, and dimensionally stable. What sets it apart is printability: it runs on a standard high-flow hotend at around 295°C with consistent layer adhesion and minimal warp, even in an unheated chamber. 3DXTech compounds it in the USA into consistent, printable filament for demanding end-use components, tooling, and fixtures.
High-temp performance with an easy-print profile.
High-modulus carbon fiber, formulated to survive heat and print clean.
HTN+CF combines a semi-aromatic high-temperature nylon backbone with high-modulus carbon fiber, so functional parts hold their shape and stiffness at temperatures where standard PA6 or PETG would soften. Low moisture absorption means it's less fussy about drying than typical nylon, and excellent chemical resistance suits automotive and industrial parts exposed to fuels, oils, and solvents — all while printing at a temperature a well-specified desktop machine can hit.
Heat resistance, stiffness, and chemical stability.
CarbonX HTN+CF is built for heat-exposed, engineering-grade parts where softening or creep would end the job. Numbers below are from the published TDS (Rev 1.0, independent third-party lab, ASTM-tested) and 3DXTech's property chart.
Deflection temperature at a full 1.80 MPa load (ISO 75) — holds shape where PA6 and PETG give up.
Rated to 20,000 hours at 150°C (IEC 60216) — for parts that live in the heat, not just visit it.
15,500 psi flat (ASTM D638) — strong, load-bearing structural parts.
977 ksi flat (ASTM D638) — high-modulus carbon fiber for stiff, lightweighted parts.
Absorbs far less moisture than typical nylon — less drying fuss, more consistent prints.
Stands up to fuels, oils, and solvents — suited to automotive and industrial service parts.
A high-flow hotend and a hardened nozzle — no chamber required.
These settings follow 3DXTech's validated TDS reference print (Bambu X1C). Carbon fiber is abrasive, so a hardened nozzle is a must; a chamber isn't required but helps on large parts.
3DXTech's reference print runs at 295°C on a Bambu X1C — reachable on any good high-flow hotend.
A heated bed around 100°C with a suitable adhesive gives reliable first-layer grip.
Consistent adhesion and low warp even in an unheated chamber; a chamber further optimizes large parts.
Use a hardened-steel or abrasion-resistant nozzle — carbon fiber wears out brass fast.
The TDS reference layer height — a solid starting point for strength and consistent flow.
Low moisture absorption for a nylon, but store sealed and dry it if it has picked up humidity.
Built for heat-exposed, load-bearing, end-use parts.
Because it stays rigid and dimensionally stable at temperature, resists chemicals, and prints without exotic equipment, CarbonX HTN+CF is a go-to for parts that go into real service — under the hood, near heat sources, and on the shop floor — not just prototypes.
Matte carbon-fiber black.
CarbonX HTN+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.

FAQ
3DXTech CarbonX HTN+CF — Common Questions
Do I need a special high-temp printer?
No exotic machine required. 3DXTech's reference print runs at about 295°C nozzle and 100°C bed on a Bambu X1C — any well-specified high-flow hotend with a hardened nozzle can print it. A heated chamber isn't required, though it helps on large parts.
How hot can HTN+CF parts get?
It has a 200°C heat-deflection temperature at a full 1.80 MPa load (ISO 75) and a 150°C continuous service rating for 20,000 hours (IEC 60216) — well beyond standard PA6 or PETG, which is the whole point of this grade.
Why do I need a hardened nozzle?
The carbon fiber that gives this filament its stiffness is abrasive and will quickly wear out a standard brass nozzle. Use a hardened-steel or other abrasion-resistant nozzle, 0.4 mm minimum.
Do I have to dry it like other nylons?
HTN+CF has low moisture absorption for a nylon, so it's less fussy than PA6. Still, store it sealed and dry it if it has picked up humidity — dry filament always gives the best surface finish and strength.
How is it different from CarbonX Nylon6+CF?
Both are carbon-fiber nylons. HTN+CF is the high-temperature grade — higher heat deflection (200°C vs 147°C), lower moisture absorption, and it prints cooler (~295°C vs 365–390°C). Nylon6+CF is the maximum-stiffness workhorse. We'll help you choose based on your part.
Is it made in the USA?
Yes — 3DXTech manufactures CarbonX HTN+CF at its 68,000 sq ft facility in Grand Rapids, Michigan, with independent third-party-lab test data and lot traceability.
