Fatigue Behaviour of Powder Steel Specimens Made by Selective Laser Melting
Original language description
The Selective Laser Melting (SLM) is an advanced technology of producing three-dimensional solid objects by 3D printing from a digital file. The article deals with fatigue push-pull testing of SLM samples to determine the dependence of their fatigue characteristics on the orientation of laser melted layers to the loading axis, the hatch spacing of the laser beam and the surface roughness of 3D printed objects. The results revealed that the transverse orientation of layers (90° to the loading axis) led to a defect type of fracture and to a lower fatigue life than that exhibited by both the horizontal (0°) and inclined (45°) orientations. The standard hatch spacing led to a higher fatigue life than the reduced one. The samples with machined and polished surfaces revealed, due to their very small averaged surface roughness, a much better fatigue resistance than that exhibited by the as-built specimens.
