Accurate solutions to manufacturing challenges

 Renishaw parts built by HSS

Renishaw, a world leading UK based metrology company manufactures a number of production parts using laser sintering technology.  In particular, the geometries shown above have a yearly production volume of 200 and have been designed for Additive Manufacture.  Recently, the company has found that the laser sintered parts often fall up to 0.4mm out of their required tolerance of 0.2mm on the straight edges.  As a result, these parts need a 100% inspection rate and experience a scrap rate of 32%. 

Jeremy Pullin, Rapid Manufacturing manager at Renishaw contacted the HSS lab at Loughborough University to help solve this problem.  From receiving the .stl file, the parts were shipped 26 hours later and their tolerances were found to be ± 0.05mm, an improvement that Jeremy found ‘truly remarkable’.  Jeremy also stated ‘the changes offered by HSS would once again make additive manufacturing the viable production route for these parts’.

The results from this case study not only impressed Jeremy, but also the American SME Society helping to cement HSS’s place as winner of the breakthrough technology award in 2009.
