With the advent of digital technology, the manufacturing industry has entered into a new era: Industry 4.0. This is characterised in particular by the interconnection of production resources, the emergence of intelligent factories and even artificial intelligence. Today, it is no longer a question of producing on a line as Henry Ford did, but of making unique and customizable products at equivalent costs despite low volumes. New design dynamics are also emerging, such as eco-design or additive manufacturing, for example, complemented by increasingly high-performance and innovative materials framed by strong environmental regulations.
