Résumé : |
Additive manufaturing (AM), by definition opposed to subtractive methods, regroups a number of manufacturing processes allowing the creation of parts from 3D numerical CAD models by building up the componnents in layers by depositing material, hence not requiring specific mould tooling design. This way, low-volume, complex parts can be produced at fixed cost in less time. This article focuses on the development and validation of additive manufacturing process simulation. |
