Textbook in PDF format In recent years, 3D printing has developed significantly and can now perform crucial roles in many applications, with the most important being manufacturing, medicine, and architecture. Using the additive process, layers of materials in liquid, solid or material form are fused together. 3D printers thus use additive manufacturing or direct digital manufacturing technology to produce proto type of a product_backup. This book contains selected topics on advanced technologies for 3D printing and additive manufacturing and how these technologies have changed the face of direct, digital technologies for rapid product_backupion of models, and prototypes
