It is a subset of additive manufacturing (AM) whereby a heat source (e.g., laser, thermal print head) is used to consolidate material in powder form to form three-dimensional (3D) objects.

Abstract
For 3D printing technology to be used at the manufacturing site, excellent 3D printers, materials, and software are essential. Moreover, in the additive manufacturing (AM) process, software simulation is becoming more important as materials are diversified, and output shapes are more complicated and larger. The goal of the AM process simulation is to prevent build-up failures by predicting the macroscopic distortion and stress of the part. In the AM process simulation, structural deflection or thermal deformation easily occurs in the case where the shape of the additive manufacturing products is large and complex. So, it is necessary to provide more optimized parameters for the build-up process and more precise production of supporters. This chapter is an example of applying AM process simulation to industrial and medical parts to produce excellent products.
