ABSTRACT
A significant increase is being seen in the application of additive manufacturing as a substitute for subtractive technologies and time-honoured procedures like casting and forging. Wire arc additive manufacturing (WAAM), which uses an arc as the energy source, metal wire as the raw material, and layers of the metal wire to be deposited on the substrate, has gained more popularity as a technology for producing components than other AM processes because it is more affordable and has shorter lead times. Due to their capacity to produce light, large, and complex metallic parts, non-ferrous metals like aluminium and magnesium alloys have grown in popularity. Due to this, businesses are now looking more closely at the method known as WAAM, which enables the production of these intricate parts. Comparatively speaking to other manufacturing techniques, WAAM also lowers production costs and permits higher customisation. Industries requiring substantial and intricate parts have become increasingly accustomed to using WAAM. It is a process that yields results of a high calibre and efficiency. A study of additive manufacturing (AM), WAAM, and current challenges in WAAM of non-ferrous alloys, particularly aluminium, magnesium, and titanium alloys, is provided in this book chapter.
