Rapid Closed-Loop Control of Additive Manufacturing with Machine Learning

Brian Giera | 17-ERD-037

Executive Summary

We are developing a machine-learning algorithm for vision-based control of additive-manufacturing processes to automatically detect problems and implement rectification strategies, thereby improving quality while reducing time and cost. This technology supports stockpile stewardship and inertial-confinement fusion programs, which require rapid build qualification for the large-scale production of high-quality parts.
