2. Defects inherent in additive manufacturing parts
Powder additive manufacturing processes are accompanied by the formation of various defects: porosity, excessive surface roughness and residual stresses. These defects and their origins are described in this section. The post-treatments developed to eliminate their effects are presented in paragraph 3 ...
