Timesaving techniques

Article Abstract:

Rapid prototyping and rapid tooling are decreasing the time-to-market for tool manufacturer products. Rapid prototyping uses stereolithography and computer-aided design (CAD) to produce three-dimensional representations. Rapid tooling uses high speed milling to create an injection moulding tool straight from a CAD file. Lead times have the potential to be reduced by half.
