Impact of Continuous Scanning Speed Variation on Microstructure in LMP-DED Additive Manufacturing

This paper deals with additive manufacturing, which enables parts with complex geometries to be produced layer by layer. For specific geometries, such as bent parts, it is necessary to vary the bead size within or between layers by modifying process…

Génération de trajectoires en fabrication additive par projection de poudre pour contrôler la géométrie et la microstructure

La fabrication additive est devenue un procédé très répandu ces dernières années en raison de sa capacité à produire des pièces de formes complexes. Cependant, malgré son utilisation généralisée, le contrôle des propriétés mécaniques des pièces…

Combining Model-based and Data-based approaches for online predictions of human trajectories

Accurately predicting human movement trajectories is of critical interest in multiple fields, including humanexoskeleton interaction. In general, such predictions can be obtained from model-based approaches (e.g., optimal control theory) or from…

A methodology for weld bead geometry and operating conditions determination in Wire Arc Additive Manufacturing

When manufacturing a part using Directed Energy Deposition (DED) pro-cesses such as Wire Arc Additive Manufacturing (WAAM), it is necessary to determine the deposition path and operating parameters (wire feed speed, torch speed, energy). While the…

L-PBF AM process failures causal chain: an FMEA-based monitoring approach for process control

The laser powder bed fusion (L-PBF) additive manufacturing process offers many advantages. How- ever, its industrial integration still needs to be improved due to the certification constraints of the produced parts. Thus, this paper proposes a…
