Some research works have sought to predict the products. An additional approach was presented by
occurrence of faults in the final product by analyzing in situ Pandiyan et al., involving two generative CNN architectures
collected data. For example, Terry et al. utilized the height based on variational auto-encoder (VAE) and general
data of high-resolution powder bed surfaces obtained from adversarial networks (GAN). These architectures were
a laser profilometer to predict the quality of products, applied and designed to predict the existence of defects
