本文件提供了通过激光束法（PBF-LB/M）粉末床熔接生产的金属生产零件的工艺评定推荐规程。本文件仅涵盖与AM设备直接相关的工艺鉴定问题，不包括除粉以外的原料鉴定或后处理。本指南涉及与AM机器和连接设备直接相关的IQ、OQ和PQ问题。物理设施、人员、工艺和材料问题仅包含在支持机器鉴定所需的范围内。

This document addresses installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) issues directly related to the additive manufacturing system that has a direct influence on the consolidation of material. The first three elements of process validation, process mapping, risk assessment, and validation planning, are necessary pre-conditions to machine qualification, however, they are outside the scope of this document. This document covers issues directly related to the AM equipment and does not cover feedstock qualification or post processing beyond powder removal. Physical facility, personnel, process and material issues are only included to the extent necessary to support machine qualification.
