3D printing materials
The right material depends on where and how your part is used. Here is how we choose.
PLA
Easy, rigid, indoor
Stiff, accurate and affordable. Great for prototypes, display parts and indoor items. Softens in heat, so avoid hot cars or direct sun.
PETG
Tough all-rounder
The sensible default for functional parts. Tougher and less brittle than PLA, handles moisture and mild outdoor exposure, better with heat.
ABS / ASA
Heat & UV resistant
Handle heat and (for ASA) sunlight far better than PLA or PETG. Ideal for automotive interiors and outdoor fittings. More demanding to print.
TPU
Flexible / rubbery
For parts that need to bend, grip or cushion — flexible mounts, bumpers, seals and grommets.
Nylon / CF
Engineering strength
High strength and stiffness, especially carbon-fibre filled. For load-bearing and engineering parts where PLA and PETG are not enough.
Frequently asked questions
Which material should I choose?+
Match it to use: PLA for indoor/prototype, PETG for tough functional parts, ABS/ASA for hot or sunny, TPU for flexible, Nylon/CF for maximum strength. Not sure? Tell us how the part is used and we will recommend one.
Is PETG waterproof?+
PETG resists moisture well and is fine for splashes and damp environments, but FDM prints are not guaranteed fully watertight without design care. Tell us if the part must hold liquid.
Can ABS be 3D printed?+
Yes. ABS and ASA print well on suitable machines and are a good choice for heat and UV resistance. They are more demanding than PLA, which is reflected in the price.
