Rationale

o Methods for anomaly and defect identification have been proposed and adopted by researchers, end users, and machine manufacturers. However, standard methods for mitigation of identified defects, or material discontinuities, are absent. This Standard will provide best practices to guide implementing and quantifying the efficacy of in-situ material discontinuity mitigation in laser-based powder bed fusion additive manufacturing. Current methods to reduce material discontinuities are costly, time intensive, and are performed post-process. The practices identified in this Standard will enable effective mitigation of material discontinuities without additional post-process procedures and at minimal cost.
