Changing the landscape of all of manufacturing, this technology has vastly streamlined conventional foundry patternmaking.
Rapid prototyping, the process of producing three-dimensional (3-D) models directly from computer-aided design (CAD) images, has been in practice for the last decade. As more developments have come to the forefront, it appears that this process will have a great impact on the metal-casting industry. It is now possible to make prototype castings with a reduced lead time and at less cost as compared with previous methods.
In the metalcasting industry, rapid prototype parts are now used to create patterns. A rubber mold can be produced from ...
