增材制造用于生产具有定制设计的开孔支架，以匹配骨性能。我们使用了三重周期性的最小表面，其尺寸和体积分数范围旨在满足不同现有骨组织的需求-这意味着制造孔径在200和500 μ m之间的亚毫米单位细胞。采用Ti-6Al-4V。压缩实验揭示了作为几何形状和密度的函数的支架的刚度和倒塌载荷。这项工作证实了所设计的网格在各种骨类型上匹配刚度和屈服强度的适用性。(C)2019 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Additive manufacturing is used to produce open-cell scaffolds with tailored design to match bone performance. We used triply periodic minimal surfaces within a range of sizes and volume fractions designed to suit the needs of the different existing bone tissues - this meant manufacturing sub-millimetre unit cells with pore sizes between 200 and 500 mu m. Ti-6Al-4V is employed. Compression experiments reveal the stiffness and the collapse load of the scaffold as a function of geometry and density. This work confirms the suitability of the designed lattices to match the stiffness and the yield strength over a wide range of bone types. (C) 2019 Acta Materialia Inc. Published by Elsevier Ltd.
