A range of RP technologies were selected to produce the components in
the most suitable materials available. Selective Laser Melting (SLM TM ) was
selected to produce the bar component due to its ability to produce parts
in corrosion resistant and rigid metals and alloys (see Section 5.5.3, for a
description of the SLM TM process). The bar was created using SLM TM in
0.05 mm thick layers using 316L stainless steel. Grit blasting and light polishing
was used to remove the rough fi nish produced by the process.
