Wire Arc Additive Manufacturing (WAAM) is a metal 3D printing technology to build near-net shape custom parts with a robot and welding torch.The WAAM process starts with a 3D CAD drawing, which is processed by software running algorithms developed by UOW over the past decade. The 3D model is sliced into many layers and each layer is automatically filled with a crisscross pattern. The robot path is automatically generated and the part is built layer by layer with a standard MIG welding torch.
Custom components have been built from specialist material such as Nickel-Aluminium-Bronze. Other materials include Aluminium and carbon steel.
One challenge is to produce thin wall structures which requires an expert knowledge of the welding process and robot path planning. Our team or researchers are achieving thin wall profiles of a few millimetres thin.
