摘要

制造骨植入物的晶格结构可以避免应力屏蔽效应,促进骨骼生长。然而,不同身体部位的骨骼性能各不相同,这给制造合适的骨植入物晶格结构造成了障碍。本文通过实验和有限元分析,系统比较了激光粉末床熔融(LPBF)加工的面心立方(FCC)、八面体和开尔文晶格结构的可成形性、各向异性、能量吸收能力、应力分布和变形模式。结果表明,开尔文晶格结构具有最佳的综合力学性能。这项研究对特定骨植入物的设计和制造具有潜在价值。

Comparative study on the process, anisotropy, and mechanical performance of laser powder bed fusion fabricated truss-lattice structures with different unit cell designs

Lattice structures to fabricate bone implants can avoid stress-shielding effects and promote bone-in-growth. However, the performance of bones varies in different body parts, creating a barrier to manufacture an appropriate lattice structure for bone implant. Here, the formability, anisotropy, energy absorption abilities, stress distribution, and deformation mode of the laser powder bed fusion (LPBF) processed face-centered cubic (FCC), Octet, and Kelvin lattice structures were systematically compared through experiments and finite element analysis. The results show that the Kelvin lattice structure had the optimal comprehensive mechanical performance. This research has potential value for the design and manufacturing of specific bone implants.

期刊介绍: The CIRP Journal of Manufacturing Science and Technology (CIRP-JMST) publishes fundamental papers on manufacturing processes, production equipment and automation, product design, manufacturing systems and production organisations up to the level of the production networks, including all the related technical, human and economic factors. Preference is given to contributions describing research results whose feasibility has been demonstrated either in a laboratory or in the industrial praxis. Case studies and review papers on specific issues in manufacturing science and technology are equally encouraged.
