Report No. ARL-TR-8795

Abstract: Additive manufacturing holds great promise for improving maintenance and sustainment operations for the military; however, concerns about part reliability persist. In this report, we discuss how smart (i.e., with machine learning) monitoring can play a role in improving confidence in 3-D-built parts. In particular, we develop and investigate a simple prototype monitoring system composed of a 3-D polymer extrusion printer and several cameras powered by real-time computer vision software and hardware. We believe that, in the future, smart monitoring will play a critical role in the certification of 3-D-printed parts.
