Abstract

We present the design and characterisation of a high-speed sintering additive manufacturing benchmark artefact following a design-for-metrology approach. In an important improvement over conventional approaches, the specifications and operating principles of the instruments that would be used to measure the manufactured artefact were taken into account during the design process. With the design-for-metrology methodology, we aim to improve and facilitate measurements on parts produced using additive manufacturing. The benchmarking artefact has a number of geometric features, including sphericity, cylindricity, coaxiality and minimum feature size, all of which are measured using contact , optical and x-ray computed tomography coordinate measuring systems. The results highligh the differences between measuring methods, and the need to establish a specification standards infrastructure for the dimensional assessment of additive manufacturing parts.
