NIST Additive Manufacturing Test Artifact
The NIST Additive Manufacturing (AM) test artifact available on this page may be used to investigate the performance and capabilities of an AM system. The test artifact is to be built using the AM system under investigation. All pertinent process parameters and machine settings used in building the test artifact should be documented. The test artifact is removed from the AM system and is measured by suitable methods for various (geometric) characteristics. The measured values (and deviations from nominal or specified values) and non-measured observed features provide an indication of the AM system’s performance, especially when compared to results from test artifacts manufactured on other comparable AM systems.Significance and Use
At the right of this page are links to download four files.
1. The test part file in .stl file format.
4. An excel spreadsheet that can be used as an inspection worksheet (“Test Artifact Inspection Sheet.xlsx”).
The general description of the test artifact available on the page along with quantitative and qualitative measurements to be taken on the test artifact to assess the performance of AM systems has been proposed for standardization through the ASTM Committee F42 on Additive Manufacturing Technologies (work item WK40419). Note that this test artifact is not yet an ASTM standard. The test artifact is under consideration by the F42 committee and further development may change the final form. http://www.astm.org/COMMITTEE/F42.htm

The test part files "NIST Test Artifact online.stl" and "NIST Test Artifact online.amf" are an experimental design. The experimental design will likely be revised based on future development and review.
