![]() ![]() The NIST test artifact was first independently modelled by each participant based upon the standard's specifications, and then models were printed on various FDM and SLA printers that used polymer and resin materials. Geometric tolerance conditions like surface flatness, roundness, and concentricity were not considered for analysis in the data collection. The geometric dimensions of the printed National Institute of Standards and Technology (NIST) test artifacts were considered for data collection. For future reusability of this data, the same NIST test artifact CAD model can be printed, and the features’ measurements can be compared with the dataset presented in this article. The percentage error between the measurement of features in the printed samples and their nominal computer aided design (CAD) values are calculated. In order to generate the data, a total of 16 samples of the test artifact were printed with fused deposition modelling (FDM) and stereolithography (SLA) additive manufacturing methods. It contains the post-processing dimensional measurements of geometric features on the printed test artifacts. ![]() This dataset records the dimensional uncertainty of selective printed features of the NIST artifact manufactured with polymer and resin printing processes. There is limited documentation on how well different additive manufacturing processes can fabricate the NIST artifact. The National Institute of Standards and Technology (NIST) standard test artifact contains a collection of various features that can be used to characterize a 3D printer's performance and has been used to benchmark metal printers. The printed features on an additive manufactured part will often deviate from the nominal values of the 3D model's features due to the factors such as printer resolution, printing parameters, printing technology, and the measurement method. ![]()
