Vacuum Casting
weekend production turnaround
Replicate parts from a 3D-printed master using a two-part silicone mould inside a vacuum chamber. The fastest, most cost-effective route from a single prototype to 15 to 30 production-quality copies, in a library of injection-mould-like materials.
×15–30 COPIES.

01 Why use it
the good bits
- Injection-mould quality without the tool cost: no steel tooling required.
- Weekend turnaround: master to 20 finished parts in 5 to 10 days.
- Full cosmetic quality: matte, semi-gloss, gloss, transparent, textured.
- Overmoulding supported: brass inserts, threaded bosses, metal pins.
- In-resin pigmentation and Pantone-match colour, per part.
- The bridge between prototype and IM, for market and clinical trials.
02 Ideal volumes
how many?
- 15–25 parts per silicone mould; up to 25 for simple geometries.
- Rubber-like, FR and GF materials yield around 15 parts per mould.
- Wax masters yield up to 30 parts per mould (investment casting).
- Multiple moulds cover 50 to 100+ unit series: faster than IM under 500 parts.
