中文摘要:
      设计了6种Ti-6Al-4V人工骨支架,利用SLM(选择性激光熔化)进行制备。采用万能材料实验机结合高速摄像机分析支架的压缩过程,并利用Ansys进行分析。结果表明:支架的立柱直径对支架的力学性能参数影响较大,横梁直径对其影响较小;在相同高度下,支架横梁直径增大、层数增多或立柱直径增大,均使结构长径比减小,使结构稳固且支架承载能力提高;支架的力学性能应与周围骨组织相匹配,经过分析,3种结构的支架力学性能参数与人体股骨相近,故可作为股骨的人工骨支架。
Structure Design of Ti-6Al-4V Artificial Bone Scaffold based on SLM

英文摘要:
      Six kinds of Ti-6Al-4V artificial bone scaffold were designed and built with SLM (Selective Laser Melting) technology. Universal material testing machine and high-speed camera were used to analyze the compression process of scaffolds, and ANSYS was used to analyze the stress of scaffold. The results showed that the vertical column diameter had a great influence on the mechanical property parameters of scaffolds but the beam diameter had little influence on them, under the same height, the increasing of beam diameter and layer or support column diameter, which result in structure length-diameter ratio decrease, so that structure firm and load-carrying capacity were improved and the mechanical property should match the surrounding bone tissue. Through the analysis, mechanical property parameters of three kinds of scaffolds were close to human femur, so they can be used as the artificial bone scaffolds of femur.
