Description
Summary:The purpose of this paper is to evaluate the capability of five desktop additive manufacturing (AM) machines based on the ability to produce a standard component. This work also developed a model/method for evaluating and ranking AM technologies based on select criteria that can facilitate purchasing decisions. A standard part was designed and printed on each machine, and evaluated based on dimensional accuracy and surface finish. Additionally, the machines were compared based on build time for single and multiple parts as well as material consumption and unit cost. The research highlights the differences between AM units and suggests a method by which to ascertain the differences. With the rapid proliferation of desktop additive manufacturing units, a quantitative ranking system was developed to rate the units so a comparison can be made. Although the focus of the work was on desktop systems, the approach can be applied across all AM technologies.
