Title: Proposal for a standardized test artifact for additive manufacturing machines and processes
Published: August 15, 2012
Abstract: 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. We review existing AM test parts, discuss the purposes of the studies, and describe important features and characteristics found in these test parts. We then propose a new test part, intended for standardization, incorporating the most useful features seen in previous test parts, with features designed to highlight process capabilities and test machine accuracy. We also discuss lessons learned in manufacturing prototype test parts by three-dimensional printing and direct metal laser sintering.
