Rationale

Equipment manufacturers and service providers publish material properties for additively manufactured components or specimens produced by pow-der bed fusion of metals using laser or electron beams. Such publications are not comparable, due to missing specifications on how associated measurements were conducted. For example, the number of specimens tested, the number of build jobs used, the specimen´s geometry and variations due to orientation are individually determined and usually not published. This document creates the prerequisites for the derivation and reporting of material properties of an AM machine uniform and transparent, in conjunction with its associated process chain. For this purpose, the boundary conditions of specimen production, sample size used and the number of build jobs to derive the indicated properties, shall be specified. Material data sheets prepared in accordance with this document will provide a suitable basis for assessment and judgement on the performance of the tested equipment and material, subject to the corresponding process boundary conditions. Once approved, this document will carry the designation of ISO/ASTM52929.
