本标准针对使用增材制造机器的聚合物零件制造服务提供商和这些服务的客户。零件的设计者以及制造服务的购买者和提供者可以在本标准的帮助下，以可追溯的方式规定所需或可实现的质量水平。本标准适用于通过激光烧结（LS）或材料挤出（MEX）由热塑性聚合物制造的零件。应在特定情况下检查其对聚合物其他工艺的适用性。质量等级适用于从建造空间拆包并拆除可能的支撑结构后未进行后处理的零件。

This document establishes the required or the achievable classes of part properties for additive manufactured polymer parts in order to get a common understanding on part quality. It is aimed at providers of manufacturing services for polymer parts who use additive manufacturing machines and at the customers for these services. Designers of parts as well as buyers and providers of manufacturing services can specify, in a traceable manner, the required or the achievable level of part properties with the aid of this document. The classification is based on mechanical, physical and geometrical properties. Further properties can be defined between buyer and provider of manufacturing. This document is applicable to parts that have been manufactured from a thermoplastic polymer by means of thermal reaction fusion of material typically applied by a powder bed fusion (PBF) or material extrusion (MEX) processes. This document is also applicable to thermoplastic parts made by other processes, provided that due consideration is given to process-specific topics. The classification of part properties applies to parts in as-built condition, that have been unpacked from the build space, with all support structures removed, but prior to any post-processing operations. Specific industries (e.g. aerospace and medical) typically specify additional requirements.
