This paper reports the results of a compression test benchmarking study carried out to investigate the mechanical properties of layer manufactured metal components in order to assess their suitability in load bearing applications. Compression tests were carried out on the DTM LaserForm ST-100 material, ARCAM processed H13 tool steel, EOS DirectSteel (50?µm), and the ProMetal material. It is concluded that the LaserForm ST-100 material, the ARCAM H13 tool steel material, and the ProMetal material all exhibit responses to compressive loads which make them suitable for use in load bearing situations, whilst the EOS DirectSteel (50?µm) exhibits a small permanent set in compression, making it less suitable in these situations.
