Composite layup with 3D printed parts
Use a printed part as the mould, or reinforce a printed part with glass or carbon fibre laid up over it.
Layup process
- 1Print the mould
- 2Seal the surface
- 3Apply release agent
- 4Lay up fibre and resin
- 5Cure and demould
Layup specification
| Use | Layup tooling, one-off to low volume |
|---|---|
| Mould material | Must survive the resin cure temperature |
| Surface | Sealed and polished; it transfers to the part |
| Watch for | Layer lines print through unless sealed |

Composite layup FAQ
What is the difference between the two modes?
In mould mode the printed part is the tool and the laminate takes its shape. In reinforced mode the laminate is laid over the printed part and stays on it.
Carbon or glass fibre?
Carbon gives more stiffness for its weight and costs more. Glass is cheaper and tougher, and insulates electrically.
Does the mould survive the resin cure?
It must. Tell us the resin system and cure temperature so we can choose a suitable material.
