Historically, standardized test parts are used to quantitatively evaluate the performance of a
machine or process. While several different additive manufacturing (AM) test parts have been
developed in the past, there are no current standard test parts. This paper reviews existing AM
test parts, discusses the purposes of the studies, and describes important features and
characteristics found in these test parts. A new test part intended for standardization is proposed.
This part incorporates the most useful features seen in previous test parts. These features are
designed to highlight process capabilities and test machine accuracy. The design has been
validated through builds by several AM processes.Mechanical Engineerin
