Titanium (Ti) plate with smooth surface was fabricated by a sputter-less selective laser melting (SLM). The vacuum SLM system employed a single mode fibre laser and two-axis galvanic mirror in order to form 3D metallic structure. In order to investigate the surface morphology on the fabricated plates, Vickers micro hardness and surface roughness Ra were measured. From the results, the Vickers micro hardness of the fabricated plates was recorded at 172 HV, higher than the typical 112±5.4 HV for a pure Ti plate.
