摘要

金属激光粉末床熔融技术成形件的质量受到设计、原材料、设备及成形过程等多环节关键变量的综合影响。本文系统梳理了上述环节中影响成形件质量的关键变量及其研究进展，旨在为建立该工艺的过程控制要求与质量管理体系奠定技术基础。综述表明，现有研究主要聚焦于单变量的独立影响，缺乏多变量耦合作用的系统分析。据此提出，未来应根据不同应用要求对成形件进行分级分类，探索建立相应的过程控制与审核标准规范，实现“生产即合格”的质量目标，从而构建可靠、高效、健康的产业发展生态。

Abstract

The quality of metal parts fabricated by laser powder bed fusion is comprehensively influenced by key variables in multiple stages

including design

raw materials

equipment

and the forming process. This paper systematically reviews the key variables affecting part quality in the above stages and their research progress

aiming to lay a technical foundation for establishing process control requirements and a quality management system for this technology. The review indicates that existing studies mainly focus on the independent effects of single variables

with a lack of systematic analysis of multi-variable coupling effects. Accordingly

it is proposed that future work should classify parts according to different application requirements

explore and establish corresponding process control and audit standard specifications

achieve the quality goal of "once parts are produced

they are qualified right now"

and thereby build a reliable

efficient

and healthy ecosystem for industrial development.
