scope:

This document covers the general description of benchmarking test piece geometries along with quantitative and qualitative measurements to be taken on the benchmarking test piece(s) to assess the performance of additive manufacturing (AM) systems. The benchmarking test piece(s) is primarily used to quantitatively assess the geometric performance of an AM system. The standard describes a suite of test geometries, each designed to investigate one or more specific performance metrics, and several example configurations of these geometries into test piece(s). The standard prescribes quantities and qualities of the test geometries to be measured, but does not dictate specific measurement methods. Various user applications may require various grades of performance. This standard discusses examples of feature configurations as well as measurement uncertainty requirements to demonstrate low and high grade examination and performance. This standard does not discuss a specific procedure or machine settings for manufacturing a test piece although these should be recorded as per ASTM F2971 and other relevant process specific specifications.
