Biography
My name is Antoine Balidas, and I am currently a Ph.D. student at the Université de Rennes, in the Institut de Physique de Rennes laboratory, and at the École Normale Supérieure de Rennes. I have a master’s degree in engineering with a specialty in mechatronics from Université de Rennes. My Ph.D. research focuses on ecodesign for additive manufacturing (AM). My work involves evaluating the environmental performance of additive and traditional processes, comparing them, and identifying the best use cases for AM technologies. I focus on comparing WAAM and green sand casting for the naval and rail sectors. The goal of my thesis is to create a decision-support tool for designers that will guide them toward solutions that reduce impact thanks to the opportunities offered by AM technologies.

9 Data analysis and life cycle assessment approach to estimate the environmental performance of WAAM
This paper proposes an approach to assess the environmental impact of wire arc additive manufacturing. It is based on life cycle assessment and structured around a four phases process tree defining a cradle-to-gate perimeter. A data analysis is conducted for all consumption and emissions considered in the process tree, and a case study is defined. The case study focuses on a duplex stainless steel propeller blade with a dual-geometry configuration, either full or with a hollow center. The results demonstrate the advantages of the proposed approach to compare manufacturing scenarios and locate impact reduction stages.
