摘要
晶格结构因其复杂多变的结构呈现出多种优异的电、磁、声学、热学和机械性能,在航空航天、汽车、建筑和生物医学行业显示出较大的市场前景,而晶格结构的制造难度大是制约其快速发展的一大难题,增材制造技术为晶格结构制造带来了便利。本文主要总结分析了晶格结构的设计、打印原材料和打印过程中参数对结构可打印性的影响,分析得出晶格结构的可打印性受晶格类型、相对密度、支柱倾斜度、粉末类型和打印参数的影响,最后提出了提升晶格可打印性的未来发展方向。
Lattice structures exhibit a variety of excellent properties due to their complex and changeable structure,indicating enormous market prospects in various industries,such as aerospace,automotive,construction and biomedical industries.However,the difficulty of fabricating lattice structures is a major problem restricting their rapid development.Additive manufacturing technology has facilitated the fabrication of lattice structures.In this work,the influences of the lattice structure design,printing raw materials and printing process parameters on the printability of a structure are summarized and analysed.The results show that the printability of the lattice structure is affected by the lattice type,relative density,pillar inclination,powder type and printing parameters.Finally,a future development direction for improving lattice printability is proposed.
