In-situ measurement and monitoring methods for metal powder bed fusion: an updated review (2021, positive): “Measuring melt pool radiation above 1000 nm was prevented, in some cases, by the optical chain (Clijsters et al 2014), but this limit was overcome in other studies (e.g. Forien et al 2020 and Yang et al 2019).”
