Abstract
Directed energy deposition is an additive manufacturing process which produces deposits by irradiating laser beam on the baseplate and supplying material powder to the meltpool. Although the material powder is generally conveyed with carrier-gas flow, the powders diffuse and some of them do not reach to the meltpool. In order to suppress the waste of materials, the particle movement should be analyzed and modified not only from the viewpoint of...
