This document deals with the technical requirements and the means for their verification for additive manufacturing (AM) machines using a bed of metallic powder, pyrophoric feedstock excluded, and a laser herein designated as machine. This document deals with all significant hazards, hazardous situations or hazardous events during all phases of the life of the machine (ISO 12100:2010, 5.4), as listed in Annex A, caused by AM machines using a bed of metallic powder and a laser when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. This document does not deal with hazards which can occur: — during the design and construction phase of the laser beam powder ped fusion (PBF-LB) machine itself; — operating in potentially explosive atmospheres. This document does not apply to technologies other than AM metals PBF-LB. This document is not applicable to machines manufactured before the date of its publication.
