Towards Manufacturing Quality Ti-6Al-4V Cantilever Struts by Selective Electron Beam Melting(SEBM)for Lattice Design

摘要：

　　Fine metal lattice structures enabled by additive manufacturing(AM)are finding increasing applications.We report a detailed study of the manufacturability of Ti-6Al-4V cantilever struts by selective electron beam manufacturing(SEBM).A total of 165 strut samples with design diameters of 0.05-3.0 mm are manufactured at 11 different inclination angles from 0° to 90°.The discrepancy between the manufactured and design diameters,surface roughness,and 3D internal defect features of these samples are characterized in detail.Essential research data are produced for the design and manufacture of quality Ti-6Al-4V struts for lattice design.
