Making of patterns on 3D printers is common today and this technology is now owned by many companies. If the final product is to be made from plastic material (ABS), then the part made on a 3D printer is fully satisfactory. If, however, the customer wants to have the final part made of metal (Al, Fe, Mg, etc.), then the pattern made on the 3D printer with the Rapid Prototyping technology needs to be transferred into the cast temper.
Technologies that are currently used for the production of precision castings in the Czech Republic allow manufacture of the castings within several weeks. The technology used at Alucast will shorten the delivery of castings from weeks to days.
