What is Vacuum Casting?
Vacuum casting, also known as polyurethane casting, is where an SLA 3D printed part is finished and used as a master & a silicone mould is created from it. This mould is then used to produce multiple copies in resin under vacuum pressure, ensuring bubble-free, high-detail results. It's a go-to method for bridge manufacturing and early product testing. Ideal for producing small to medium quantities of high-quality parts on-demand, similar to injection moulded parts.
An accurate production technique that can replicate detailed patterns, complex dimensions, and different textures. Vacuum casting also is ideal for parts that require overmoulding.
