Abstract
In order to use 3D printing technology as a sanction, it is necessary to optimize topology, component unification, and reduce weight need for advanced manufacturing design. In the case of metal 3D printing, it is necessary to manage deformation and defects in the process cause of using laser, and support generation and design optimization must be accompanied for efficiency. Currently, design progresses through simulation before actual production in AM field. This chapter explores design in additive manufacturing.

Study and Application of Machine Learning Methods in Modern Additive Manufacturing Processes
Directed energy deposition (DED) is a three-dimensional printing process which practices a focused energy source, for example the electron beam, laser, or a plasma arc to liquefy a material which is instantaneously dropped from nozzle ( Figure 4 ).
