Additive manufacturing is an innovative way to produce complex parts. Nowadays, knowledge about mechanical properties and production costs are well known. Many studies found in the literature present comparisons between different additive manufacturing technologies based on technical or economical criterions. However, the environmental analysis of the phenomena that occur during the manufacturing step is still limited. To ensure the development of these processes it seems important to get predictive models of the environmental impacts, allowing to evaluate the product from a technical, economic and environmental point of view. This paper presents a new methodology for the environmental impact evaluation, combined with a technical and economical assessment. This methodology is applied on multiple additive manufacturing processes and will help manufacturers like a decision-making tool to make a choice of manufacturing process based on multiple criterion.
