This document defines the requirements for manufacturing centers, in which additive manufacturing methods are used (referred to below as additive manufacturing centers), which are independent of the material and manufacturing method used. This document specifies criteria for additive manufacturing processes as well as quality-relevant characteristics and factors along the process chain and defines activities and sequences within an additive manufacturing center. This document is applicable to the additive manufacturing technologies defined according to DIN EN ISO/ASTM 52900 and follows an approach oriented to the manufacturing process.
