In-situ measurement and monitoring methods for metal powder bed fusion: an updated review (2021, unknown): “In the seminal works of Schwerdtfeger et al (2012), Rodriguez et al (2012), Ridwan et al (2014) and Mireles et al (2015), layer-wise IR vision was used to characterise the surface pattern of printed areas to detect flaws and surface anomalies.”
Process defects and in situ monitoring methods in metal powder bed fusion: a review (2017, unknown): “Other authors (Schwerdtfeger et al ., 2012; Ridwan et al ., 2014; Rodriguez et al ., 2012 – 2015; Mireles et al ., 2015; Dinwiddie et al ., 2013) used the second viewport on the top of the chamber, close to the beam column.”
Additive manufacturing process monitoring and control by non-destructive testing techniques: challenges and in-process monitoring (2018, background): “The feasibility of adopting thermography for inprocess inspection of the building platform in AM equipment has been proven (Bayle and Doubenskaia 2008, Schwerdtfeger et al. 2012, Dinwiddie et al. 2013).”
Laser powder-bed fusion additive manufacturing: Physics of complex melt flow and formation mechanisms of pores, spatter, and denudation zones (2015, background): “While these pores are observed at the part level, the defects are seeded at the single layer level [38] and are most likely related to trapped partially melted particles.”
Review of in-situ process monitoring and in-situ metrology for metal additive manufacturing (2016, methodology): “The electron beam process requires a near vacuum [28], as the mean free path of electrons is very short; an added bonus is that there is no oxygen to cause oxidisation.”
