摘要：

Quality control in terms of material health, texture and workpiece geometry is not assured in additive manufacturing. Many literature studies address quality issues on a scale of less than one millimeter. On the other hand, few works concern geometrical defects at the level of the piece as a whole (form and dimension), on a scale therefore greater than several millimeters. From the existing bibliography and the authors' experience, the objective of the article is to list the typologies of geometrical defects usually encountered and the configurations in which they appear.
