FDM PPA-CF High Temperature Carbon Fibre Nylon

Name: FDM PPA-CF High Temperature Carbon Fibre Nylon 3D Printing
Brand: RYSE 3D

The stiffest grade we print — a high-temperature polyphthalamide (PPA) reinforced with 15% carbon fibre for an 8,700 MPa modulus, 98 MPa tensile strength and a 192 °C heat deflection temperature, with a 230 °C Vicat softening point. RYSE 3D prints PPA-CF in a dedicated high-temperature chamber and anneals every part as standard, so the rated numbers are the numbers you receive. For heat-exposed brackets, fixtures and tooling where standard nylon softens or creeps.

Overview

Rigid at temperature, not just at room temperature

Most engineering nylons quote a strength figure measured in a comfortable lab. PPA-CF is specified for the other case — the bracket bolted next to an exhaust, the fixture that sits in an oven, the tool that has to hold tolerance while everything around it gets hot. Polyphthalamide is a high-temperature polyamide by design: a 230 °C Vicat softening point and a 232 °C melting point, with 15% carbon fibre taking the stiffness to 8,700 MPa and bending strength to 145 MPa. It is the most rigid material in our FDM range.

One thing matters more than any single number here: annealing. Straight off the plate, PPA-CF has a heat deflection temperature of just 84.5 °C. Annealed, that becomes 192 °C — a 108 °C swing, along with a jump in modulus from 7,800 to 8,700 MPa. We anneal every PPA-CF part as standard, so the published figures are the ones your parts actually arrive with. Plenty of suppliers quote the annealed numbers and ship unannealed parts; we would rather tell you the difference exists.

Applications

What PPA-CF is used for

Heat-exposed brackets, fixtures and tooling — the parts that live where standard nylon would soften, creep or walk out of tolerance. Rigidity and a 1.37% water absorption figure also make PPA-CF a strong choice away from heat entirely, wherever a part must stay stiff and dimensionally stable in wet or weather-exposed service — including cosmetic parts, finished in-house to a textured or A-class standard.

Why PPA-CF

Why choose FDM PPA-CF

●

The stiffest grade we print

An 8,700 MPa Young’s modulus and 145 MPa bending strength — when deflection under load is the failure mode, nothing else in our FDM range is more rigid.

●

192 °C heat deflection

Parts hold their shape where standard nylon softens or creeps — with a 230 °C Vicat softening point and a 232 °C melting point behind it.

●

Annealed as standard

Unannealed, PPA-CF deflects at 84.5 °C. We anneal every part, so you receive the 192 °C material — not the datasheet’s optimistic cousin.

●

1.37% water absorption

Lower moisture pickup than any other nylon we print — against 2.2% for COPA and 3.33% for PA6-GF — so properties and dimensions hold in ordinary humid air.

●

Dimensionally stable, low warp

Evenly distributed chopped carbon fibre builds a reinforcing network that resists warping and holds accuracy across complex geometry.

●

Finished in-house

Bead blasted, smoothed, primed or A-class painted — one team prints, finishes, anneals and inspects it, with 1–3 day express available.

Design guidance

Annealing trade-off	The same cycle reduces notched impact from 11 to 6.3 kJ/m² and elongation from 2% to 1.6% — heat and stiffness are bought with toughness
Load orientation	Strongest in-plane — we orient load paths at quote
Moisture	1.37% water absorption (ISO 62), the lowest of our nylon grades — stable in ordinary humid service
Finish	Bead blasted, smoothed, primed or A-class painted in-house

Honest limits

Where PPA-CF is the wrong call

Engineering materials are picked on what they can’t do as much as what they can. If any of these apply, we’ll spec you a better grade — free, with your quote.

Parts bigger than 340 mm

PPA-CF runs in our high-temperature chamber, capped at 340 × 320 × 340 mm. For large one-piece parts up to 900 mm, PA6-CF reaches 109 MPa and 215 °C on the large-format platform.

Impact & flexing features

Annealed PPA-CF is rigid rather than tough — 6.3 kJ/m² notched and 1.6% elongation. Where repeated impact loading is the main duty of the part, PA12-CF gives 22.8 kJ/m² and 8.4%; for snap-fits and living hinges, MJF PA 11 Gen2.

Sustained heat above 192 °C

Where tooling has to hold tolerance right at the top of the range, PET-CF carries a 205 °C heat deflection temperature with more ductility, printed in the same chamber.

Flame-rated parts

PPA-CF carries no flame rating. Where ignition rather than heat is the constraint, specify PC-FR flame-retardant polycarbonate or our UL94 V-0 SLA resin.

Compare

PPA-CF vs the other high-temperature grades

PPA-CF is the rigid one — the highest modulus in our FDM range, built for heat-exposed parts that must not deflect. For peak strength and heat in a large-format part, see PA6-CF; for tolerance held in heat and humidity, PET-CF, printed in the same chamber. For impact toughness, PA12-CF; for rigidity on a budget at ambient temperature, PA6-GF. For production nylon at volume, powder-bed MJF may suit.

Property	PPA-CF (this page)	PA6-CF	PET-CF
Tensile strength	98 MPa	109 MPa	74 MPa
Heat deflection	192 °C	215 °C	205 °C
Elongation at break	1.6%	2.1%	4.5%
Impact, notched	6.3 kJ/m²	11 kJ/m²	8.6 kJ/m²

FAQ

FDM PPA-CF FAQ

What is PPA-CF high temperature nylon?

PPA-CF is a polyphthalamide — a high-temperature polyamide — reinforced with 15% carbon fibre and printed in our dedicated high-temperature chamber. It is the most rigid grade in our FDM range at 8,700 MPa, with a 192 °C heat deflection temperature and a 230 °C Vicat softening point, for parts that must stay dimensionally honest while hot.

How strong and stiff is PPA-CF?

98 MPa tensile strength, 145 MPa in bending, and an 8,700 MPa Young’s modulus — the highest of any material we print in FDM. Stiffness is the point: where the failure mode is deflection under load rather than outright fracture, PPA-CF resists it better than our carbon nylons.

How much heat can PPA-CF take?

Annealed, PPA-CF has a 192 °C heat deflection temperature at 0.45 MPa and 119 °C at 1.80 MPa, backed by a 230 °C Vicat softening point and a 232 °C melting point. That covers heat-exposed brackets, fixtures and tooling. For sustained service right at the top of the range, PET-CF reaches 205 °C.

Why do PPA-CF parts need annealing?

Because unannealed PPA-CF deflects at just 84.5 °C. The annealing cycle raises heat deflection to 192 °C and modulus from 7,800 to 8,700 MPa. It is a genuine trade — notched impact falls from 11 to 6.3 kJ/m² and elongation from 2% to 1.6% — but for a high-temperature grade the heat and stiffness are the reason you chose it. RYSE 3D anneals every PPA-CF part as standard, so the published figures are the ones you receive.

Does PPA-CF absorb moisture?

Less than any other nylon we print: 1.37% water absorption to ISO 62, against 2.2% for PA6/12-CF COPA and 3.33% for PA6-GF. Properties and dimensions hold in ordinary workshop humidity without conditioning — and in genuinely wet service too: we print PPA-CF paddle blades that spend their working life in water.

What is the difference between PPA-CF, PA6-CF and PET-CF?

PA6-CF is the strongest at 109 MPa and 215 °C, and the only one of the three that prints up to 900 mm. PET-CF holds tolerance in heat and humidity with 4.5% elongation. PPA-CF is the rigid one — the highest modulus we offer, for heat-exposed parts that must not deflect. Tell us the job, the temperature and the environment and we’ll spec the right grade free with your quote.

How much does PPA-CF 3D printing cost in the UK?

It depends on part size, geometry and quantity — so rather than quote a misleading headline figure, we price it on screen in seconds. Upload a STEP or STL to our instant online quote, select FDM PPA-CF and the price comes back immediately, with volume pricing running to 100,000 parts. There is no minimum order, no tooling cost and no setup charge, and annealing is included in the price rather than added as an extra.

How fast can I get PPA-CF parts?

Express turnaround is available from 1–3 days. Because we print, anneal, finish and inspect PPA-CF in-house in Shipston-on-Stour, nothing is subcontracted and no part of the job waits in another supplier’s queue. Tell us the deadline with your quote and we’ll confirm what is achievable for your geometry.
