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.

The ten FDM materials side by side. Typical values; properties vary with geometry and orientation. Every figure is confirmed on your instant quote.

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.

Also known as carbon fibre nylon, PA6 carbon, CF nylon.
The rigidity leader — high stiffness and strength-to-weight, with the highest tensile strength and heat deflection of our FDM grades.
Best for: Brackets, mounts, jigs and functional prototypes.
Also known as PA12 carbon, nylon 12 CF, low-moisture carbon nylon.
The most ductile carbon nylon we run — 12% elongation at break with low moisture pickup, so parts flex rather than crack and hold dimension in humid service.
Best for: Detailed functional parts and fixtures in humid or handled service.
Also known as glass filled nylon, PA6 glass, GF nylon.
Glass reinforcement for rigidity and shape-stability under load and mild heat — parts that must stay dimensionally honest.
Best for: Rigid parts that must hold their shape under load and mild heat.
Also known as carbon co-polyamide, COPA CF, PA6/12 carbon.
The toughest grade in our FDM range — 22.8 kJ/m² notched impact alongside a 194 °C heat deflection temperature and low moisture pickup.
Best for: Parts that take knocks while holding heat and dimension.
Also known as high-performance polyamide, PPA carbon, high-temp nylon CF.
A high-performance polyamide that holds strength and dimensions at elevated temperature, printed in a dedicated heated chamber. Figures are the annealed condition.
Best for: Heat-exposed brackets, fixtures and tooling (non-critical).
Also known as PET carbon, carbon PET, high-temp PET.
One letter from PETG-CF, nearly 3× the heat resistance — 205 °C HDT with low moisture pickup for tolerance-holding tooling.
Best for: Weld fixtures and jigs that hold tolerance in heat and humidity.
Also known as flame retardant polycarbonate, FR PC, fire-rated PC.
Flame-retardant PC/ABS for protective casings and enclosures where ignition, not heat, is the constraint. The base resin is rated UL94 V-0 at 1.5 mm.
Best for: Protective casings and enclosures where flammability is the constraint.
Also known as ABS plastic, acrylonitrile butadiene styrene.
The cost-effective all-rounder — quick fit-check and form models, and the toughest of our general-purpose grades on impact.
Best for: Cost-effective prototypes, fit-check and form models.
Also known as UV-stable ABS, ASA plastic, weatherable ABS.
ABS’s outdoor cousin — UV-stable and weatherable, so enclosures and covers keep their colour and properties outside.
Best for: UV-stable outdoor parts, enclosures and covers.
Also known as carbon PETG, PETG carbon fibre, CF PETG.
Carbon-filled PETG for stiff technical brackets at ambient temperature — add heat and it softens; step up to PET-CF.
Best for: Stiff brackets and fixtures at ambient temperature.
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.
Pick the highest it will ever see, not the average.
Longest dimension. Bigger than the bed? We split, print and bond.
Quantity changes which process is cheapest per part.
Stiff holds shape under load. Tough takes a hit without cracking.
Features that flex need elongation, which rules out the stiffest grades.
Choose PA6-CF for the highest stiffness and heat, or PA6-GF for rigidity on a budget.
PA6/12-CF COPA takes the hardest knocks at 22.8 kJ/m²; PA12-CF is the most ductile at 12% elongation.
