... to improve the service performance of metal parts. Design/methodology/approach This paper develops a dynamic model for LDED repair process by considering the interaction of laser beam and powder stream. The repaired surface morphologies under the different process parameter conditions are calculated...

...Shijie Jiang; Mingyu Sun; Yang Zhan; Hui Li; Wei Sun Purpose The purpose of this study is to set up a dynamic model of material extrusion (ME) additive manufacturing plates for the prediction of their dynamic behavior (i.e. dynamic inherent characteristic, resonant response and damping) and also...

... conditions to minimize process errors, such as nozzle clogging. Nozzle clogging is one of the most significant process errors in current FDM machines, and may cause serious consequences such as print failure. This paper aims to present a physics-based dynamic model suitable for monitoring nozzle clogging...
