L-PBF and DED processing of a Ni-based superalloy

Different additive manufacturing (AM) technologies such as L-PBF and DED do become really attractive for both repair and 3D part manufacturing. In particular, extensive work is in progress for the non-weldable nickel-based superalloys which tend to…

Revisiting the influence of the scanning speed on surface topography and microstructure of IN718 thin walls in directed energy deposition additive manufacturing

Controlling the mechanical properties of metallic parts produced by additive manufacturing remains challenging. The mechanical behavior of parts is mainly related to the microstructure, which depends on process parameters and manufacturing…

Une approche unifiée pour la mesure et l'analyse des défauts de forme des pièces mécaniques

To reduce post-processing and improve acquired data quality, it is intended to work out a mesurement system allowing to deliver a description of the acquired geometry in a predefined base of defects. This system will lean on techniques of…

Contributions à la modélisation géométrique du dépôt de matière pour l'élaboration d'un jumeau numérique du procédé WAAM

Wire and arc additive manufacturing processes are rising as they offer high deposition rates and minimize environmental and security issues due to the use of metal powders. Even if the process derived from welding is well-known, its use on robot to…
