Investigation of Effect of Processing Parameters for Direct Energy Deposition Additive Manufacturing Technologies

In order to capitalize on the cost-effectiveness of additive manufacturing (AM), it is critical understand how build components with consistency and high quality. Directed energy deposition (DED) an AM method for creating parts layer by through use a moving heat source powder material inserted into melt pool generated substrate. DED, like most processes, highly complex due rapid thermal gradients experienced during processing. These are determined variety processing parameters, which include laser power, feed rate, travel speed, height hatch spacing, etc. A lot effort has been carried out in community what these parameters they influence gradients. Despite all efforts, industries rely trial-and-error-based approach find right set produce quality part. This time-consuming not cost-effective technology. The aim our research reduce amount experimental data combination numerical analysis optimize this relationship. Physics-based two-dimensional melt-pool modeling results from OPTOMEC 850M LENS will be utilized investigate effects geometry, study provide key guidelines achieve desirable clad geometry efficiency DED method.
