Carbon fibre (CF) 3D printing
Carbon fibre plastics (PLA-CF, PETG-CF, PA-CF) have short carbon fibres mixed into the filament. Parts come out stiffer, lighter and more dimensionally stable than with the base plastic, with a matte finish that hides layer lines. Heat and chemical resistance depend on the base: PA-CF handles the most.
What it is good for
- Brackets and arms that must not flex
- Drones, RC and weight-critical parts
- Jigs and templates with stable dimensions
- Technical car and motorbike parts (PA-CF)
When not to use it
- Parts that must bend or take impacts
- Clips and snap fits
- Parts that must insulate electricity
Carbon fibre (CF) vs Glass fibre (GF): Compared with glass fibre: stiffer and lighter, but more brittle and more expensive. Glass fibre handles impacts better and insulates electricity. See Glass fibre (GF) →
