Belkacem Bouzouidja is a mechanical engineer and doctoral candidate specializing in the design of aluminium alloys for additive manufacturing, particularly laser powder bed fusion (LPBF). He is currently pursuing his PhD at Mines Saint-Étienne in France, where his research focuses on optimizing aluminium alloys for LPBF processes by combining advanced mechanical and process performance criteria with genetic algorithm-based optimization. Belkacem graduated from the Ecole Nationale des Ingénieurs de Metz (ENIM) with a degree in mechanical engineering, specializing in materials applied to industrial processes. Prior to this, he completed a Diplôme Universitaire et Technologique in Mechanical and Production Engineering at the Institut Universitaire et Technologique de Metz. His professional experience includes several internships and engineering projects where he applied his academic knowledge to practical challenges. Notably, he worked on the machining of Ti6Al4V parts fabricated by 3D LPBF at LEM3, focusing on microstructure, machining conditions, and process optimization. Belkacem’s competencies include materials characterization, mechanical testing, CAD and mechanical simulation software (Solidworks, Abaqus, Catia), and programming (Python, VBA). With a solid academic foundation and hands-on experience, Belkacem is committed to advancing additive manufacturing technologies by designing high-performance alloys tailored to modern industrial needs.
