The Vacuum casting technology allows us to create polyurethane resin parts by using a silicone mould. To manufacture this mould, we usually use a pattern made by stereolithography. Nevertheless, we can build a silicone mould almost using any piece made with other technologies as a master piece: sintering, FDM, machined, modified old part… We can produce a short set of serial parts with polyurethane resin with characteristics like flexibility, transparency, high temperature resistance, fiber load or flame retardant (V0), similar to the final product: ABS, PX, PC
There are also FDA-approved polyurethanes suitable for food use.
