Vacuum Casting

An ideal choice for both rapid prototyping and low volume production of end-use products or parts.

Range of finishing options | High-detailed | Repeatable

What is Vacuum Casting?

Vacuum casting is where an SLA or SLS printed part is used as a master & a silicone mould is created from it. Polyurethane resin is poured into the mould under vacuum to produce the part. 

An accurate production technique that can replicate detailed patterns, complex dimensions, and different textures.


  • Cost-efficient alternative to hard tooling.
  • Accurate & detailed.
  • Strong optical properties.
  • Adjustable hardness.


  • Small batches of end-use product runs.
  • Functional & visual prototypes.
  • Concept & appearance models.
  • Automotive parts.
