Investigation on Mechanical Properties Anisotropy of Rod Units in Lattice Structures Fabricated by Selective Laser Melting

摘要：

　　Lattice structure with high strength and low mass using selective laser melting(SLM)has been a hot topic.However,there are some problems in the fabrication of lattice structure by SLM.Rod unit is the basic component of lattice structure and its performance affects the whole structure.It is necessary to investigate the influence of selective laser melting on rod units mechanical properties.A series of rod units with different inclination angle and diameter were fabricated by SLM in this research.And the mechanical properties of these units were measured by tensile test.The results show that the rod units with different diameters and inclination angles have good mechanical properties and show no difference.It is a good news for lattice structure designing for there is no necessary to consider the mechanical properties anisotropy of rod units.
