The process is then repeated, layer by layer until the metal part is completed. You can see the process in action here: WAAM can work with a wide range of metals, provided they are in wire form. When using certain materials, like titanium, shielding is necessary to create an inert atmosphere to ensure the right building conditions. The essence of arc additive manufacturing is a buildup welding process essentially. 0000115625 00000 n A tool-path generation strategy for wire and arc additive manufacturing Elle s’impose de plus en plus comme une méthode de production rapide et peu onéreuse de composants et marchandises, également en métal comme avec le Wire Arc Additive Manufacturing (WAAM). Introduction Additive manufacturing (AM), also known as rapid forming technology, was proposed by Charles W. Hul in the 1980s [1]. Wire+arc additive manufacture Welding capillarity Point source conduction ABSTRACT An analytical process model for predicting the layer height and wall width from the process parameters was developed for wire+arc additive manufacture of Ti-6Al-4V, which includes inter-pass temperature and material properties. Wire Arc AM is a logical choice because this material is typically used to 0000120874 00000 n 0000007777 00000 n Unlike the more common metal powder AM processes, WAAM works by melting metal wire using an electric arc as the heat source. Unlike PBF AM machines, which have a limited build envelope, the robotic arm of a WAAM machine has more freedom of movement, meaning that the size of a component isn’t limited by space, but only by the distance the robotic arm can reach. More recently, the MX3D team used its technology to 3D print an aluminium bike frame. By using WAAM to manufacture this component, the team saved more than 200 kg of material per item, and was able to consolidate two parts of the vessel into one. Additive Manufacturing with Wire.
