Three-dimensional printing, which appeared in the 1980s and has been steadily improving ever since, is a new and very promising technology. Thanks to its unique process of depositing material layer by layer, it differentiates itself from the rest of the traditional methods of modeling by molding and removing material. Modeling by adding material allows 3D printing to create parts with very complex geometries, and even with unprecedented precision. This last characteristic allows it to be used in many sectors including aviation, automotive, production but also science, education and medicine. With regard to these latter fields of application, printing by adding material is for some authors a real revolution. For modeling learning and training mockups, manufacturing custom prostheses, or printing biological and functional organs, the range of possible uses for 3D printing seems immense and very promising. In this study, we invite you to discover the main applications of the 3D printer in veterinary medicine
