Defect Classification for Additive Manufacturing with Machine Learning

open access: yesMaterials, 2023
Additive manufacturing offers significant design freedom and the ability to selectively influence material properties. However, conventional processes like laser powder bed fusion for metals may result in internal defects, such as pores, which profoundly affect the mechanical characteristics of the components.
