Additive Manufacturing Processes — Lesson 3

This lesson covers the introduction to the welding process, specifically focusing on the wire additive manufacturing process. It explains the additive manufacturing process, which is a layer-by-layer deposition process that forms a 3D object. The lesson discusses the importance of this process in the field of advanced technology and how it is still being researched. It also explains how the process is digitally controlled to determine the path, shape, and thickness of the layer being deposited. The lesson further discusses the different methods of producing 3D printing, such as stereolithography, fused deposition modeling, selective laser melting, and selective laser sintering. It also explains the different types of additive manufacturing processes, such as liquid-based, powder-based, and solid-based technologies. The lesson concludes by discussing the benefits and limitations of wire arc additive manufacturing technology.
