Die Integration des pulverbettbasierten Schmelzens mittels Laserstrahl (PBF-LB) in industrielle Prozessketten wird aktuell durch verschiedene Herausforderungen gehemmt. Hierzu zählen vor allem niedrige Aufbauraten sowie hohe Energie- und Ausschusskosten. Daher soll mit einer geeigneten thermischen Prozessüberwachung, einer multikriteriellen Optimierung des Prozesses sowie der Technologie des variablen Laserspotdurchmessers ein wirtschaftlicherer PBF-LB-Prozess realisiert werden.
Currently, a number of challenges restrict the implementation of laser-based powder bed fusion (PBF-LB) in existing manufacturing processes. These challenges mainly include low build-up rates and high energy and scrap costs. Therefore, a more economical PBF-LB process has to be put into practice by means of suitable thermal process monitoring, multi-criteria process optimization, as well as variable laser spot diameter technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
