Te Evolution of AM Standards: From F2792 to ISO / ASTM 52900

ASTM F2792 was first issued in 2009 tone create a context language for additiva producturing. It defined terms such as context quite; build platform, context quentext; context quantit; layer quatines, context; and context; powder bed fusion, context; which are now ubiquitous iten industry.
