To facilitate adoption in high consequence applications, fundamental questions regarding the intrinsic reliability of additive metals must be answered. Defect “signatures” are being investigated to provide a predictive framework for quantifying material performance distributions. Signatures for critical defects in stainless steel alloys will be discussed from multiple techniques that span in-situ process monitoring, post-process computed tomography, metallography and tensile testing. Process signatures will be of particular focus and will address thermal, optical and acoustic domains with the intent to quantify melt pool dynamics and defect formation in-situ.
