加法制造(AM)，也被称为3D打印，已经被强调为传统(减法和成形)制造的补充方法。这主要是由于其独特的特性，可以直接生产复杂的形状和组件，而不需要组装过程。在这些方面，AM已经影响了产品的设计和形成的方式，这导致了一个专门的研究领域，称为为AM设计(DFAM)。作为解决DFAM的一个步骤，本文回顾了将原始模型重新设计为AM中产生的组件的文献，称为ASPART分解(PD)。尽管与零件合并(PC)相比，PD在DFAM中受到的关注较少，即将部件重新设计为一个统一的单一部件，但对于AM来说，PD的研究动机和挑战多种多样为了调查PD的研究趋势，37种主要出版物被归类为五个动机，包括可印刷性、生产力、功能性、艺术性和灵活性。此外，从技术和方法方面，将相关研究分为分解问题(自动、半自动和手动分解)、积聚问题(单件和多件的定位决策和布局问题)和装配问题(连接设计和装配工艺规划)。正如这篇全面的综述所证明的那样，PD的概念给跨越几个学科的进一步研究带来了挑战。沿着这条主线，我们从三个主要方面进一步阐述了产品开发的未来研究方向：(1)提高大规模定制的AM生产率；(2)开发新的分解方法和指南；(3)将传统设计方法应用于产品开发。
Additive Manufacturing(AM), also known as3D printing, has been highlighted as a complementary method to the traditional (subtractive and formative) manufacturing. This mainly results from its distinctive characteristics to directly produce complex shapes and assemblies without an assembly process. With these aspects, AM has affected the way products are designed and formed, which leads to an exclusive research area, known asDesign for AM (DfAM). As a step towards addressing DfAM, this paper reviews the literature on re-designing an original model into assemblies produced in AM, named asPart Decomposition (PD). Although PD has received less attention in DfAM compared withPart Consolidation(PC)that is re-designing assemblies into a consolidated single part, PD has been studied with various motives and challenges for AM. To investigate the research trend in PD, 37 main publications are categorized under five motives including printability, productivity, functionality, artistry and flexibility. Additionally, from technical and methodological aspects, relevant studies are organized into decomposition issues (automatic, semi-automatic and manual decompositions), buildup issues (orientation decision for single- and multi-part and packing problem), and assembly issues (connection design and assembly process planning). As witnessed in this comprehensive review, the concept of PD leaves further research challenges spanning several disciplines. Along this line, we further elaborate future research directions of PD under three main categories: (1) enhancing the AM productivity for mass customization; (2) developing novel decomposition methods and guidelines; and (3) applying conventional design methodologies to PD.
