An Evaluation of Rapid Prototyping “Concept Modelling” Techniques for New Product Development

Rapid Prototyping systems use layer technology to build physical prototypes directly from 3D Computer Aided Design (CAD) data. This provides the opportunity to design more complex parts and assemblies which cannot be made by existing technologies [1]. This paper reviews the emerging technology of low cost 3D printing techniques initially used for “concept modelling”, to prove design intent and visualisation of these complex designs, but now being applied to end usage applications. Concept modellers such as 3D System’s ThermoJet, Z-Corp’s 3D Printer, ObJet’s Quanda, Stratasys’ Dimension and EnvisionTec’s PerFactory will be examined. A case study is used to show how these low cost systems can substantially reduce new product development time by their utilisation as production processes
