Assessment of optical emission analysis for in-process monitoring of powder bed fusion additive manufacturing

Assessment of optical emission analysis for in-process monitoring of powder bed fusion additive manufacturing

Developing methods which allow real-time monitoring of powder bed fusion (PBF) additive manufacturing (AM) processes is key to enabling in situ assessments of build quality (e.g. lack of fusion and porosity). Here, we investigate the use of optical emission spectroscopy and high-speed (100 kHz) meas...
