ABSTRACT

Design for Additive Manufacturing (DfAM) is an essential method of product design and development process. The product design analysis, including improved production, is carried out according to the key parameters of Additive Manufacturing (AM), such as layer thickness, build orientation, creation of support and slicing planning. The production parameters, together with the AM method and the type of material, significantly influence product quality through surface finish and strength. The paper presents an approach that helps users define layer thickness by evaluating the design with several attributes, where both strength and surface roughness are criteria of interest for improving product quality. Weighted features, DfAM knowledge and a multi-attribute decision support tool, are used to recommend the most desirable layer thickness. Additive powder samples were used in the case study to show how the proposed approach contributes to product quality.

摘要

增材制造设计（DfAM）是产品设计和开发过程的基本方法。产品设计分析（包括改进的生产）是根据增材制造（AM）的关键参数进行的，例如层厚度，构建方向，支撑的创建和切片计划。生产参数以及AM方法和材料类型会通过表面光洁度和强度显着影响产品质量。本文提出了一种方法，可通过评估具有几个属性的设计来帮助用户定义层厚度，其中强度和表面粗糙度都是提高产品质量的重要标准。加权功能，DfAM知识和多属性决策支持工具用于推荐最理想的层厚度。
