A novel thermo-geometrical model for accurate keyhole porosity prediction in laser powder-bed fusion

HIGHLIGHTS

• who: Emanuele Vaglio from the University of Udine, Via delle Scienze, Udine, Italy have published the paper: A novel thermo-geometrical model for accurate keyhole porosity prediction in Laser Powder-Bed Fusion, in the Journal: (JOURNAL)
• what: In this work, a new semi-analytical model for the keyhole porosity prediction is presented. This work will be considered as the starting point to develop the first part of the model . The general model performance was evaluated by computing its balanced accuracy, which can be expressed as follows: Nff 1 Nkk + Abal=(17) 2 Nk,tot Nf . . .
