Rev1 PAHT-CF The High-Temperature, Carbon-Fiber Engineering Nylon
The High-Temperature, Carbon-Fiber Engineering Nylon
PAHT-CF is a high-temperature polyamide compounded with chopped carbon fiber — the highest-heat, top-tier engineering nylon we stock. It holds its shape and strength at temperatures that would soften PA6, PA12, or standard PA-CF, so parts keep working under the hood, near motors, and in high-heat tooling. The carbon fiber makes it extremely stiff and strong with an outstanding strength-to-weight ratio, slashes shrinkage and warping for excellent dimensional stability, and the nylon base keeps its low moisture uptake, chemical, fuel, and oil resistance. A genuine metal-replacement, industrial-grade material for under-hood automotive, aerospace, high-temperature jigs and fixtures, and structural high-heat brackets. This is the most demanding nylon to print: very high hot-end temps, an enclosure, and a hardened-steel nozzle are required. One color — Natural (carbon-charcoal), on 1 kg spools.

High-temp, stiff, vacuum-sealed, supported by humans.
Rev1 PAHT-CF is precision-extruded 1.75 mm high-temperature carbon-fiber-reinforced filament, wound evenly and vacuum-sealed with desiccant — its carbon fiber adds stiffness and its high-temp base holds parts strong and stable in the heat — then made-to-order and supported from Auburn Hills, Michigan.
When the part has to run hot, stay stiff, and survive.
PLA is easy but soft and melts in a warm car; PETG is tough but flexes; even PA12-CF gives up strength as temperatures climb. Rev1 PAHT-CF is a high-temperature polyamide reinforced with chopped carbon fiber — the highest-heat nylon we make. It holds shape and load at temperatures that soften PA6, PA12, and standard PA-CF, so it thrives under the hood, near motors, and in high-heat tooling. The carbon fiber makes it extremely stiff and strong with an outstanding strength-to-weight ratio, and cuts shrinkage and warping for excellent dimensional stability, while the nylon base keeps its low moisture uptake and outstanding chemical, fuel, and oil resistance. It prints the hottest of any nylon — very high hot-end temps in an enclosure — and because carbon fiber is abrasive, it needs a hardened-steel nozzle. This is an advanced, industrial material, not a beginner one. Give it a dry spool and Rev1 PAHT-CF makes rigid, heat-resistant, metal-replacement parts in a Natural carbon-charcoal finish.
Even diameter and a clean wind for demanding runs.
Round, consistent 1.75 mm carbon-filled filament feeds smoothly so long, very hot enclosed prints don’t fail.
Every Rev1 PAHT-CF spool is wound evenly and held to a tight diameter, so it feeds without under-extrusion across a full 1 kg run. Vacuum-sealed with desiccant to arrive dry — and remember carbon fiber is abrasive, so run a hardened-steel nozzle.
Holds shape and strength far above PA6, PA12, and standard PA-CF for hot, load-bearing parts.
Carbon fiber drives rigidity and modulus high enough to replace metal in structural parts.
Carbon fiber reduces shrinkage and warping for better dimensional stability than unfilled nylon.

Print settings for high-temp carbon nylon.
PAHT-CF is the most demanding nylon to print — it runs the hottest and needs a proper high-temperature setup. Plan on a very hot end, a hot bed, and an enclosure; a machine that tops out at standard nylon temps won’t reach it. Two non-negotiables: carbon fiber is abrasive, so a hardened-steel nozzle is required, and the spool must be dry. Get those right and PAHT-CF rewards you with stiff, heat-resistant, dimensionally stable parts.
Carbon fiber is abrasive — run a 0.4 mm+ hardened-steel nozzle; brass wears out fast.
Runs very hot — you need an all-metal, high-temp hot end for strong layer adhesion.
A hot bed plus glue or an adhesive sheet locks down the first layer on this high-temp nylon.
An enclosed, draft-free chamber is required to hold heat and keep large parts from warping.

| Setting | Recommended | Notes |
|---|---|---|
| Nozzle type | Hardened steel (required) | Carbon fiber is abrasive — a hardened-steel nozzle is mandatory; brass wears out quickly. |
| Nozzle temperature | 290–310 °C | Runs very hot — an all-metal, high-temp hot end is required for strong layer bonding. |
| Bed temperature | 90–110 °C | Glue stick or an adhesive sheet on glass/PEI for a strong first layer on this high-temp nylon. |
| Chamber / enclosure | Required, warm, draft-free | An enclosure is required — PAHT-CF prints hot and needs even chamber heat to stay flat. |
| Print speed | 30–60 mm/s | Moderate speeds help interlayer strength. |
| Part cooling fan | 0–10 % | Keep cooling very low — too much fan weakens layer bonding on high-temp nylon. |
| Retraction | 1–5 mm | Direct drive: ~1–2 mm. Tune to control stringing. |
| Nozzle size | 0.4 mm + hardened | Larger hardened nozzles add strength on functional parts and clear carbon fill. |
| Drying | 80–90 °C · 8–12 h | Required — dry the spool before every print for best strength and clean high-temp extrusion. |
| Post-processing | Sand / anneal | Optional annealing can further boost heat resistance and dimensional stability. |
Stiff, high-heat parts that carry load.
The high-temp carbon-fiber nylon behind stiff, heat-resistant parts.
PAHT-CF trades easy printing for genuine industrial performance: the highest heat resistance of the nylons, extreme stiffness and strength-to-weight, low warp, plus the toughness, low friction, and standout chemical resistance of the nylon base. Made-to-order in one industrial Natural carbon-charcoal finish, on 1 kg spools, shipped from Michigan.
Gears that mesh, slide, and hold size when hot.
Added carbon-fiber stiffness and high-heat stability for parts that turn under load near heat.
PAHT-CF pairs nylon’s slippery, wear-resistant surface with carbon-fiber rigidity for gears, worm drives, and moving mechanisms — and the high-temperature matrix keeps tooth geometry stable where lower-temp nylons deflect or soften as things heat up.
Drag chains that stay rigid in hot machinery.
Stiff, fatigue-resistant carriers for moving cable runs near heat.
Cable drag chains flex constantly under load — exactly the repeated-stress duty nylon is built for. PAHT-CF adds carbon-fiber stiffness and high-heat resistance so carriers hold shape and resist sag through thousands of cycles, even in warm machine enclosures.
High-temp jigs and fixtures that hold tolerance.
Stiff, chemical-resistant tooling that stands up to heat and repeated use.
Print the fixtures, jigs, and assembly aids your line needs — PAHT-CF stays rigid and dimensionally stable through clamping, heat, solvents, and abrasion, cycle after cycle, without flexing or softening where lower-temp materials give up.
Bushings and bearings that run smooth and hot.
A low-friction nylon surface stiffened with carbon fiber for high-heat duty.
One of nylon’s superpowers: it slides. Bushings, bearing blocks, and slides in PAHT-CF run smoothly and resist wear, while carbon fiber and the high-temp base keep them dimensionally true under load and near heat.
Metal-replacement brackets that take the heat.
Rigid and heat-resistant — ideal for structural housings and engine-bay hardware.
PAHT-CF’s stiffness, strength, and high heat resistance make it a strong pick for under-hood brackets, structural housings, and mounts — the carbon fiber keeps walls rigid and flat, and the high-temp base holds up where standard nylons soften. The industrial carbon-charcoal finish looks the part on end-use hardware.
From prototype to a part that ships and runs hot.
Stiff, light, and heat-resistant enough for real-world, load-bearing components.
Brackets, mounts, and functional end-use parts — PAHT-CF bridges prototyping and production with the heat resistance, stiffness, strength-to-weight, chemical resistance, and dimensional stability to go into demanding service. Ask us about case pricing.
PAHT-CF vs. PA12-CF vs. PC.
Pick by how hot the part has to run. PAHT-CF wins on heat resistance, stiffness, and dimensional stability — the highest-heat nylon of the three; PA12-CF is stiff and strong but softens sooner and is easier and cheaper to print; PC is tough and heat-resistant but more prone to warping and moisture. PAHT-CF is the hardest to print and the most expensive — in return for top-tier, high-temperature, metal-replacement performance.
| Rev1 PAHT-CF | PA12-CF (Carbon Nylon) | PC (Polycarbonate) | |
|---|---|---|---|
| Heat resistance | Highest — high-temp nylon | Good — softens sooner | High |
| Stiffness / rigidity | Highest — carbon-fiber reinforced | High — carbon-fiber reinforced | Moderate |
| Dimensional stability | Highest — low warp & shrink | High — low warp | Moderate — warp-prone |
| Chemical / fuel resistance | Outstanding | Outstanding | Moderate |
| Ease of printing | Hardest — very hot, enclosure & hardened nozzle required | Moderate — hardened nozzle, heat, enclosure | Hard — hot & warp-prone |
| Relative cost | Highest — premium | Moderate | Moderate |
| Best for | High-heat / structural / metal-replacement | Stiff / structural / lightweight | Tough / impact / heat |
General material guidance; exact performance depends on part geometry, print settings, and grade. For lower-temp stiffness at lower cost and easier printing, consider PA12-CF or PA-CF; for easy everyday prints, consider PLA or PETG; for maximum impact and chemical toughness, consider PC.

FAQ
Rev1 PAHT-CF High-Temp Carbon Fiber Nylon — Common Questions
How is PAHT-CF different from PA12-CF?
Both are carbon-fiber nylons, but PAHT-CF is built on a high-temperature polyamide, so its headline advantage is heat: it holds shape and strength at much higher temperatures than PA6, PA12, or standard PA-CF (heat-deflection roughly in the ~130–180 °C range). Like PA12-CF it’s extremely stiff and strong with an excellent strength-to-weight ratio, low warp, low moisture uptake, and chemical resistance — but it keeps performing where PA12-CF starts to soften. The trade-off is that PAHT-CF is harder to print and costs more. If parts run hot, PAHT-CF is the upgrade.
Do I need a hardened-steel nozzle?
Yes — this is required. Carbon fiber is abrasive and will quickly wear out a standard brass nozzle, so run a 0.4 mm or larger hardened-steel (or equivalent wear-resistant) nozzle. It’s one of the non-negotiables for any carbon-filled filament. PAHT-CF also prints the hottest of the nylons: hot end 290–310 °C, bed 90–110 °C, a required enclosure, and very low part cooling — so you also need an all-metal, high-temperature hot end.
What is PAHT-CF best used for?
It’s the high-heat, metal-replacement workhorse for demanding structural parts: under-hood automotive brackets and housings, aerospace components, high-temperature jigs and fixtures, and structural high-heat mounts. Its combination of top-tier heat resistance, extreme stiffness, high strength-to-weight, and low warp makes it ideal wherever a part has to stay rigid and hold size in the heat — and the nylon base still brings chemical, fuel, and oil resistance for exposed parts.
Do I need to dry PAHT-CF, and do I need an enclosure?
Yes to both. Like any nylon PAHT-CF must be printed dry — dry the spool (80–90 °C) before printing so layers bond and parts reach full strength. An enclosure is required, not just recommended: it prints very hot (290–310 °C nozzle, 90–110 °C bed) and needs a warm, draft-free chamber to hold heat and keep large or flat parts from warping. Keep part cooling very low and use glue or an adhesive sheet for first-layer grip — and always with a hardened-steel nozzle.
PAHT-CF vs PA12-CF vs PC — which should I use?
Choose PAHT-CF when heat resistance is the priority and you want the stiffest, most dimensionally stable, metal-replacement nylon for high-temperature parts. Choose PA12-CF (or PA-CF) when you want carbon-fiber stiffness at lower temperatures with easier printing and lower cost. Choose PC when you need maximum impact toughness. For simple, easy prints, PLA or PETG are the better picks — PAHT-CF is an advanced, industrial material, not a beginner one.
When should I choose PA12-CF or plain nylon instead?
If your parts don’t run hot, PA12-CF or PA-CF give you similar carbon-fiber stiffness with easier printing and a lower price. For maximum toughness and ductility, use plain PA12 or PA6; for easy everyday prints, use PLA or PETG; for high impact and chemical resistance, use PC. PAHT-CF is the pick when high-temperature performance and metal-replacement rigidity matter most — not when you need a budget or easy-printing material.
What color and finish does PAHT-CF come in?
One color — Natural (carbon-charcoal). The chopped carbon fiber gives it an industrial carbon-charcoal finish that looks the part on structural, end-use hardware. It ships on 1 kg spools. Because it’s a single high-temperature reinforced grade, there are no transparent, conductive, or other color options.
What size is available, how much, and how fast does it ship?
One color — Natural (carbon-charcoal) — on a 1 kg spool at $64.99. In-stock spools ship fast from Auburn Hills, Michigan. Add it to your cart in the buy-box, or call (248) 707-2950 for case quantities and standing orders.
