摘要
传统CAD建模技术因其自身的局限性,极大地限制了增材制造产品的设计空间.为了最大限度地发挥增材制造的技术优势,需要在产品设计阶段通过综合产品形状、大小、层次结构以及物质组成实现产品性能的最优化及制造成本的节约化.本文根据增材制造的4种特性,从复杂形状建模、复杂材料建模、复杂层次建模以及面向制造的建模等4个方面论述了国内外对于面向增材制造的正向产品建模技术的研究概况.在此基础上,本文对该领域的发展趋势进行了探讨,认为综合一体化建模与轻量化建模将成为未来发展方向.
The intrinsic limitations of traditional CAD modeling severely restrain the design space of additive manufacturing（AM）. In order to maximize the technological superiority of AM, great effort should be madeto optimize product performance and save manufacturing cost through considering the shape, size, hierarchical structure, and material composition in the design phase. According to AM characteristics, this paper summarizes the state-of-the-art research of AM product modeling in the following four aspects： complex shape modeling,complex material modeling, complex hierarchy modeling, and modeling for manufacturing. Based on this, future development trends in this field are discussed. Integrated modeling and lightweight modeling are considered as the potential development direction of AM product modeling.
