From Cad and Rp to Innovative Manufacturing

From CAD and Virtual Prototyping, there are already available many Rapid Prototyping (RP) techniques to produce physical, hand hold able parts. A brief overview is presented of some important aspects regarding how to get a good 3D solid model, how to transfer it to RP machines and how to produce quickly a physical prototype. The RP models could be used for different downstream applications. The paper gives some alternative tooling routes, depending on some criteria, such as: volume production, material and complexity of the parts. The RP models could be used as master models for vacuum casting, metal spraying, investment casting and other innovative manufacturing techniques.
