Lately researchers have been paying more attention to the environmental aspect, especially since our planet is nowadays threatened by multiple phenomena. In this context as a manufacturing process, the additive manufacturing appeared as a trend in its domain because it’s economic, eliminates raw material waste and allows to make complex shapes, which may not be obtained by conventional manufacturing processes. There are many additive manufacturing processes, this research will focus only on Wire Arc Additive Manufacturing which has an impact on the environment, by consuming energy (for welding, for cooling, moving the nozzle) and gases. In this paper will provide an overview to the different studies related to the environmental aspect of this process, where some have concentrated on the parameters that surround the product, other studies focused on the parameters related to the process. We will group all the ideas to find an application of the process in the context of sustainable development.
