A benchmark component has been designed to test the geometrical capabilities of the photo-polymerisation, selective laser sintering, laminated object manufacturing and fused deposition modelling layer manufacturing rapid prototyping processes. It assesses not only linear accuracies but geometric tolerances, repeatability, resolution limits and the ability to create manufacturing features such as fillets and draft angles.

Repeatability measurements on the benchmark show that the layer manufacturing technologies rank differently in the small scale (less than 5mm), the medium scale (20 to 25mm) and the large scale (up to 250mm). The superiority of the photo-polymerisation processes in the small scale is lost at medium and large scales. Measurement ranges are mainly from 0.05 to 0.5mm.
