Abstract

Devices, systems, methods, and kits of parts for monitoring operation of an electron beam additive manufacturing systems are disclosed. A monitoring system includes one or more measuring devices (130) positioned on the at least one wall in the interior (122) of a build chamber (120) of the additive manufacturing system (100). Each one of the one or more measuring devices (130) includes a piezoelectric crystal (132). The monitoring system further includes an analysis component (150) communicatively coupled to the one or more measuring devices (130). The analysis component (150) is programmed to receive information pertaining to a frequency of oscillation of the piezoelectric crystal (132). A collection of material on the one or more measuring devices (130) during formation of an article (116) within the build chamber (120) causes a change to the frequency of oscillation of the piezoelectric crystal (132) that is detectable by the analysis component (150) and usable to determine a potential build anomaly of the article (116).
