Benchmark Study Compares Rapid Prototyping Systems

A new rapid prototyping benchmark study compares the performance of seven 3D printer rapid prototyping systems in the areas of time, cost and quality. The report, produced by T.A. Grimm & Associates, Edgewood, KY, finds that five of the seven systems qualify as 3D printers, as defined by the Rapid Prototyping Index. The index incorporates 13 performance measures, and rates systems in four application areas: concept models, form and fit prototypes, functional prototypes and patterns. The study found a large difference in prototype costs, ranging from approximately US$60 to US$267, as well as variations in the cost of accessories, labor and materials.
