Additive Manufacturing (AM) opens a new dimension to the industry. Beyond the facilitated design, it is also the prospect of producing ever more complex parts while rationalizing the loss of materials. It is therefore at the crossroads between design, processes and material properties that this manufacturing method is developing at record speed. This white paper analyzes the internal Additive Manufacturing process, best practices for the management of the AM process, and how to concretely implement good practices for the organization and optimization of the productivity.
