中文摘要：

3D打印有效地填补了数字化模型设计与真实产品制造之间的鸿沟,将产品设计与制造两阶段更紧密地关联在一起.与传统制造技术相比,它有效地降低了制造约束条件与制造技能要求,因此它有力地推动了个性化产品的设计制造与相关研究.在此背景下,文中面向3D打印,围绕近年来3D模型设计的结构分析与优化大量相关工作,从节省材料、增加强度、提高稳定性和支撑优化4个方面分别介绍了这些工作的研究目标、算法思想及研究结果,最后对这4方面工作进行了总结,并结合当前的技术发展水平,从研究与应用的角度探讨了一些具有挑战性的未来工作.

英文摘要：

3D printing technologies have created a bridge between digital3D models and modern productdevelopment and become more and more popular in industrial practice.Compared to the traditional manufacturingtechnologies,3D printing has significantly reduced the manufacturing constraints and decreases themanufacturing skill requirements.Therefore it has effectively promoted the design and manufacture of personalizedproducts.This paper provides an intensive survey on the works on structural analysis and optimizationin designing3D models for3D printing purposes,with a classification of this huge field of researchand discuss about the relation between the single algorithms and a list of desirable objectives in structuralanalysis.Specifically,it has overviewed various aspects of structural analysis including material saving,strength enhancement,stability improvement,and support structure optimization.Finally,this paper offersan analysis of the state of the art while discussing open and challenging problems from both an academic andan industrial perspective.
