What is PPA-CF?
PPA-CF is polyphthalamide, a semi-aromatic high-performance nylon, reinforced with chopped carbon fibre. It is the stiffest material in our lineup and keeps its strength well past 200 °C, with excellent resistance to oils, fuels and coolants. That makes it a metal-replacement candidate for brackets, fixtures and housings that sit next to engines, heaters or hot tooling. It needs a long, hot drying cycle and a hardened nozzle, billed as a flat handling surcharge on top of the per-gram rate. Reach for it when PAHT-CF still isn't stiff or heat resistant enough.
We usually recommend PPA-CF when someone wants to replace a machined aluminium part, or when a part has to sit next to an engine, a heater or hot tooling and still hold a tight tolerance. Its resistance to oils, fuels and coolants also makes it a good fit for workshop and automotive fixtures. It is matte black only and among the most expensive materials we stock, so send us the part's operating temperature and load: if PAHT-CF or PA-CF will do the job, we'll tell you.
Best uses
- ▸Metal-replacement brackets
- ▸Fixtures for hot tooling and moulds
- ▸Engine-bay and exhaust-adjacent parts
- ▸Coolant and fuel-exposed components
- ▸High-stiffness structural frames
- ▸Motor and heater housings
Pros
- ✓ Highest stiffness we offer
- ✓ Heat resistance above 200 °C
- ✓ Excellent resistance to oils, fuels and coolants
- ✓ Very low creep under sustained load
- ✓ Minimal warping for an engineering polymer
- ✓ Premium matte-black engineering finish
Cons
- ✗ Needs a long, hot drying cycle before every print
- ✗ Abrasive — requires a hardened/wear-resistant nozzle
- ✗ One of the most expensive materials we offer
- ✗ Matte black finish only, no colour options
- ✗ Brittle compared with nylon — snap-fits can crack
- ✗ Advanced difficulty — needs a heated chamber and a tuned profile
Key properties
Which carbon-fibre material is right for you?
All four are reinforced with chopped carbon fibre, print in matte black and carry a flat handling fee for drying and a hardened nozzle. Start with PA-CF and step up only when the part's heat, humidity or chemical exposure calls for it. If the part stays under about 100 °C and isn't load-critical, PETG, ASA or PC will be cheaper and faster.
PA-CF
The default carbon-fibre choice.
Choose it when the part carries real load, needs to be stiff and light, and stays below about 150 °C in a normal indoor environment. It is the most affordable of the four.
Look elsewhere if it sits somewhere hot and damp for long periods, or near oils and fuels.
About PA-CF →PAHT-CF
For parts that run hot or live somewhere humid.
Choose it when the part sits in a car, beside a motor or in a warm enclosure (up to about 180 °C), or press-fits and bolt holes must hold their size in Singapore’s humidity.
Look elsewhere if it sees sustained heat above about 180 °C or harsh chemicals.
About PAHT-CF →PPA-CF
This pageMaximum stiffness, a stand-in for machined metal.
Choose it when you are replacing an aluminium part, the part must not flex or creep under load, it runs above 200 °C, or it is splashed with oil, fuel or coolant.
Look elsewhere if it has snap-fits, clips or living hinges, or the budget matters more than the last bit of stiffness.
PPS-CF
Extreme heat, chemicals and flame resistance.
Choose it when the part is exposed to solvents, acids or fuels, needs to be flame retardant (battery and electrical enclosures), or sits next to an oven or heater (up to about 260 °C).
Look elsewhere if it takes knocks or has to flex at all. It is stiff but brittle, so keep it to static parts.

From our workshop
PPA-CF needs a long, hot drying cycle and a hardened nozzle before we run it, billed as a flat handling fee on top of the per-gram rate and shown separately on your quote. It is stiff but less forgiving than nylon, so avoid thin snap-fits and live hinges; design generous fillets instead. Turnaround may run longer than PLA or PETG jobs. If your part stays below about 150°C, PA-CF will usually do the job for less.
