Modélisation de la performance environnementale des procédés de fabrication par ajout de matière Application à la projection de poudres métalliques
Additive manufacturing is an innovative process to produce mechanical parts. However, it generates environmental impacts are still unknown. To ensure the development of manufacturing processes by adding material, it is important to develop the concept of DFSAM (Design for Sustainable Additive Manufacturing). Indeed, one of the objectives of sustainable manufacturing is to minimize the total flow consumed (electricity, material, fluids...) during production step. For this it is interesting to propose a predictive model of consumption in the integrated design loop, allowing to assess the environmentalimpact of a product during its manufacture.The work of this thesis focuses on the modeling and assessment of environmental impacts of these processes and more specifically for powder projecting technology. This work helped to establish a new methodology of the environmental performance of the set part-process based on the whole impacts sourcesrelated to the manufacturing process. The methodology developed is increasingly interested in all the stages necessary for the production of a mechanical part (rawmaterial production to the finishing step).This manuscript is divided into five chapters that can present the general context of the study, the state of the art, the methodology developed, an application of the methodology to projecting powders manufacturing process and the computer tool developed during this thesis. The last chapter is devoted to the conclusion on the contributions of this work and provides research perspectives.
