This course aims to study the interactions of materials, shapes and processes in the design and industrialization of technical objects. Based on real case studies, this module will address the manufacturing processes of plastic and metallic materials, the strategies to a material (functional criteria and implementation) and a process (economic and technical criteria) as well as the definition of a shape (functional criteria, process and material). We will focus in processes involving transformations of matter: injection, extrusion, thermoforming for polymers, etc., plastic deformations for metals, the addition of 3D matter in additive manufacturing on metallic materials and plastics.
