3-Dimensional heat transfer modeling for laser powder-bed fusion additive manufacturing with volumetric heat sources based on varied thermal conductivity and absorptivity
Zhidong Zhang,Yuze Huang,Adhitan Rani Kasinathan,Shahriar Imani Shahabad,Usman Ali,Yahya Mahmoodkhani,Ehsan Toyserkani +6 more
TL;DR: In this paper, a 3D heat transfer finite element model for laser powder-bed fusion (LPBF) was developed for accurately predicting melt pool dimensions and surface features, which can be used to reduce the process/material development costs.
Journal ArticleDOI
On the measurement of relative powder-bed compaction density in powder-bed additive manufacturing processes
Usman Ali,Yahya Mahmoodkhani,Shahriar Imani Shahabad,Reza Esmaeilizadeh,Farzad Liravi,Esmat Sheydaeian,Ke Yin Huang,Ehsan Marzbanrad,Mihaela Vlasea,Ehsan Toyserkani +9 more
TL;DR: In this paper, a nano-computing tomography (CT) system was used to obtain an estimation of the relative powder-bed compaction density along the recoater moving direction.
Journal ArticleDOI

Shahriar Imani Shahabad,Zhidong Zhang,Ali Keshavarzkermani,Usman Ali,Yahya Mahmoodkhani,Reza Esmaeilizadeh,Ali Bonakdar,Ehsan Toyserkani +7 more
TL;DR: In this paper, an efficient numerical-experimental approach has been introduced to calibrate the parameters of a proposed three-dimensional (3D) conical Gaussian moving laser heat source model.
Journal ArticleDOI
On the effect of thin-wall thickness on melt pool dimensions in laser powder-bed fusion of Hastelloy X: Numerical modeling and experimental validation
Shahriar Imani Shahabad,Usman Ali,Zhidong Zhang,Ali Keshavarzkermani,Reza Esmaeilizadeh,Alireza Bonakdar,Ehsan Toyserkani +6 more
TL;DR: In this paper , a 3D heat transfer model is developed to investigate the influence of the thickness of the printed thin-walls on melt pool dimensions and temperature distribution, which can be extended to the multi-track simulation for investigating the effect of thin-wall thicknesses on Melt pool geometries.
