Abstract Scope |
The advent of additive manufacturing (AM) has revolutionized the production of complex components, particularly in aerospace and biomedical fields. This research simulates melt pool dynamics in wire-based and powder-based directed energy deposition (DED) using a discrete element method (DEM). It examines the effects of various energy sources, such as lasers, electron beams, and arcs, on melt pool formation during deposition. The simulations reveal thermal profiles, fluid flow patterns, and solidification behavior, crucial for predicting the final build's quality and mechanical properties. Different beam parameters and their interactions with wire and powder feedstock are modeled to optimize process conditions and enhance efficiency. The study also explores the influence of deposition speed, feed rate, and energy density on melt pool characteristics. Leveraging advanced modeling capabilities, this research aims to optimize AM processes, leading to the production of components with superior properties and reduced defects, advancing AM technologies in various industrial applications |
