Additive manufacturing increasingly represents an attractive alternative to established manufacturing methods for companies. The trend towards complex parts, decentralised manufacturing and customised products allows economically viable application for a wider area. This applies to an increasing number of serial applications, which pose new requirements to the processes performance. In particular components used industrially (automotive, mechanical engineering, railway, aerospace, processing plants, medical, etc.), high quality and safety requirements are to be fulfilled. The present dearth of norms and standards means that processes for the manufacturing of parts need to be defined from scratch for each individual case, which entails a high degree of expense and which permits little transparency and hence little trust amongst stakeholders in the process. If industrial parts are produced via additive manufacturing techniques, it shall be verified that these meet the requirements placed on them. To this end, the process chain and environment shall be designed so that the process quality and resultant product quality remain consistent and reproducible at all times. The following clauses outline the relevant requirements to establish quality-assured processes in additive manufacturing. This document has the aim of outlining the requirements as an integral whole (not product specifically), which are necessary as a basis for designing processes for high-quality additively manufactured parts. In particular in regulated industries, such as the automotive industry, mechanical engineering, the rail sector, aerospace, process and industrial systems or medical technology, consideration of the criteria defined within the framework of this document will establish a basis for fulfilling the requirement for specific products. Important measures relating to the AM process chain are defined for this, which are to be controlled and monitored in order to ensure a reproducible quality of AM parts. As this document is not intended to be technology-dependent, the subprocesses are applicable or can be disregarded, depending on the technology used. This document provides a common approach for the proper manufacturing of additively manufactured series and replacement parts. In this way, the scope of a supplier audit can be rendered significantly leaner if the requirements of this document are fulfilled.
