摘      要：Porous scaffolds as succedaneum of natural bone were investigated and applied in medical *** this work, we carried out studies on mechanical properties of solid parts and porous scaffolds obtained by additive manufacturing(AM) *** is found that productions of AM process have a higher yield strength and higher microhardness compared to commercial *** surface was observed for layer-by-layer process of AM and sticking of powder *** machining accuracy is affected by both dimensions and ***, mechanical properties of porous scaffolds are influenced by machining accuracy and *** addition, the unit cell structures also impact the mechanical properties of porous scaffolds in terms of elastic modulus, yield strength and failure ***,considering the mechanical properties and biological properties, scaffolds with cube(CB) crystal cells are the best choice in our study.
