  • Investment Casting | RPS Neo | Stereolithography

    With investment casting, a master pattern would usually be sculptured, machined or moulded in either wood or wax. The master pattern is then sent to a foundry where it will be encased in ceramic to create a mould. Once it hardens, molten metal is poured inside the mould and once cooled, the ceramic is removed to produce the final metal part.
