A New 3D Benchmarking Artifact to Evaluate Dimensional Accuracy and Geometric Tolerancing of Additive Manufacturing Technique

Abstract

A variety of additive manufacturing (AM) techniques is available commercially based on a different principle. Benchmarking is a technique to investigate the overall performance of manufacturing technique with the aid of benchmark artifact. This paper aims to propose a new 3D artifact to check dimensional accuracy and geometric tolerancing in all three dimensions. The artifact can predict the effect of machine movement on variation in dimensional accuracy of artifact in a respective direction. Thus, the design of artifact covers maximum geometrical allowance. The artifact can be used to examine the dimensional accuracy and geometric tolerancing of single AM technique or for comparing two different AM techniques along the three dimensions.
