Geometrical metrology for metal additive manufacturing



Richard Leach, David Bourell, Simone Carmignato, Alkan Donmez, Nicola Senin, Wim Dewulf


Metal additive manufacturing technologies facilitate the production of highly complex geometries - this presents designers with many opportunities for high-value sectors but results in manufactured geometries and surfaces that can be difficult to measure. The needs, requirements, on-going and future research issues in geometrical metrology for metal additive manufacturing are addressed. The infrastructure under development for specification standards in AM is presented, and the research and developments in the geometrical dimensioning and tolerancing for AM are reviewed. Post-process metrology is covered in detail, including the measurement of surface form, surface texture and internal features. In-process requirements and developments in AM are discussed and the materials metrology that is pertinent to geometrical measurement is reviewed. Issues of traceability, including various benchmarking artefacts, are presented. The information in the technical review sections is pulled together in a synthesis of current requirements and future research topics.
