FDM 3D Printing Materials

The ten FDM (fused deposition modelling) engineering materials we run — fibre-reinforced, high-temperature and technical thermoplastics, zero hobby plastic. Carbon- and glass-filled nylons for rigid load-path parts, PPA-CF and PET-CF where standard nylon softens, flame-retardant PC-FR, and ABS, ASA and PETG-CF for the everyday. Big, rigid parts up to 500 × 500 × 900 mm, printed, finished and inspected under one roof. Full material properties and best uses below.

Impact methods differ: PA12-CF is measured by Izod ISO 180, the rest by Charpy ISO 179. The two are not directly comparable — the figures are listed for reference, not as a ranking. PC-FR’s supplier data sheet publishes no notched impact value.

Material selector

Which 3D printing material do I need?

Six questions, about twenty seconds. Tell us what the part has to survive, how big it is and how many you need — we’ll narrow twenty-four production grades down to the two worth quoting.

0 of 6 answered 24 materials match
1Which materials should we consider?
2How hot does the part get in service?

Pick the highest it will ever see, not the average.

3How big is the part?

Longest dimension. Bigger than the bed? We split, print and bond.

4How many do you need?

Quantity changes which process is cheapest per part.

5What matters mechanically?

Stiff holds shape under load. Tough takes a hit without cracking.

6Any clips, snap-fits or living hinges?

Features that flex need elongation, which rules out the stiffest grades.

+Any special requirements? optional
FAQ

FDM materials FAQ

What materials can be used for FDM 3D printing?
RYSE 3D runs ten FDM engineering materials: carbon-filled nylons PA6-CF and PA12-CF, glass-filled PA6-GF, tough PA6/12-CF COPA, high-temperature PPA-CF and PET-CF, flame-retardant PC-FR, and technical grades ABS, ASA and PETG-CF — fibre-reinforced and technical thermoplastics, zero hobby plastic.
What is FDM (fused deposition modelling) best for?
Big, rigid, engineering-grade parts without the tooling bill — brackets, mounts, enclosures, ducting, jigs and manufacturing tooling up to 500 × 500 × 900 mm in one piece, with 1–3 day express turnaround.
How big can FDM parts be printed?
Our large-format envelope is 500 × 500 × 900 mm in one piece for all standard grades, plus a dedicated 340 × 320 × 340 mm high-temperature chamber for PPA-CF, PET-CF and PC-FR. Bigger than the bed? We split, print, bond and inspect the finished assembly.
Which FDM material is the strongest?
PA6-CF leads on tensile strength (109 MPa) and heat deflection (215 °C) — the pick for maximum rigidity. PA6/12-CF COPA takes the biggest hits at 22.8 kJ/m² notched Charpy impact, and PA12-CF is the most ductile at 12% elongation.
Which FDM material is most heat-resistant?
PET-CF holds a 205 °C heat deflection temperature and PPA-CF 192 °C — both printed in a dedicated heated chamber, for tooling and fixtures where standard nylon would soften, creep or walk out of tolerance.
Do you offer a flame-retardant FDM material?
Yes — PC-FR, a flame-retardant PC/ABS whose base resin carries a UL94 V-0 rating at 1.5 mm, for protective casings and enclosures where ignition is the constraint. That rating is not automatic certification of a finished part, so tell us the wall thickness that must be rated and we will confirm it with your quote.
What is the difference between PA12-CF and PA6/12-CF COPA?
Both are low-moisture carbon nylons. PA12-CF is the more ductile at 12% elongation with 100 MPa tensile and a 176 °C heat deflection. COPA is the tougher on impact at 22.8 kJ/m² notched with a higher 194 °C heat deflection, at 92 MPa tensile and 8.4% elongation. Choose PA12-CF for parts that flex and get handled, COPA for parts that take knocks while holding heat.
Which FDM material is the toughest on impact?
PA6/12-CF COPA at 22.8 kJ/m² notched Charpy, followed by ABS at 21.5 and ASA at 19.6. Note that PA12-CF’s 13 kJ/m² is measured by Izod ISO 180 rather than Charpy ISO 179, so it does not sit on the same scale.
Where can I find FDM material properties and datasheets?
Headline properties for all ten materials are on this page, full figures are on each material page, and every grade has a downloadable datasheet — or have the numbers confirmed with your instant online quote.

Guidance

How to choose an FDM material

Need maximum rigidity?

Choose PA6-CF for the highest stiffness and heat, or PA6-GF for rigidity on a budget.

Need toughness or ductility?

PA6/12-CF COPA takes the hardest knocks at 22.8 kJ/m²; PA12-CF is the most ductile at 12% elongation.

Need real heat?

Go PET-CF (205 °C HDT) or PPA-CF (192 °C) — printed in a dedicated high-temperature chamber.

Need a flame rating or outdoor life?

PC-FR for flame-retardant casings; ASA for UV-stable outdoor parts; ABS for cost-effective fit-checks.

Send the CAD. We'll spec the grade.

Upload your part for an instant online quote in any FDM material, printed and finished in the UK — and if FDM isn't the right call, we'll point you straight to SLS, SLA or MJF.
