Optimisation de trajectoire pour le procédé de fabrication Laser Powder Bed Fusion (LPBF)

Le procédé de fabrication additive par fusion laser sur lit de poudre (LPBF) est un procédé couche par couche consistant à faire fusionner de la poudre au passage d’un laser. Malgré les nombreux avantages qu’elle présente, cette méthode de…

Calibration of galvanometric scan heads for additive manufacturing with machine assembly defects consideration

The calibration of additive manufacturing machines using scanning heads in processes such as Laser Powder Bed Fusion (LPBF) and vat photopolymerization is an iterative and time-consuming process often based on limited physical models. Indeed, the…
