Journal ArticleDOI
Evaporation model for beam based additive manufacturing using free surface lattice Boltzmann methods
TL;DR: In this article, an evaporation model for beam-based additive manufacturing processes, such as selective electron beam or selective laser melting (SEBM/SLM), is presented.
Journal ArticleDOI
Modelling of electron beam absorption in complex geometries
TL;DR: In this paper, an electron beam model based on a set of semi-empirical equations available from different published literature and on theoretical considerations is proposed to analyze the attenuation of the electron beam as it passes through the sample.
Journal ArticleDOI
Numerical simulation of multi-component evaporation during selective electron beam melting of TiAl
TL;DR: In this paper, the relation between energy input, evaporation and residual porosity is numerically investigated on the titanium aluminide alloy Ti-48Al-2Cr-2Nb.
Journal ArticleDOI
A multi-component evaporation model for beam melting processes
TL;DR: In this article, a numerical model based on a two-dimensional free surface lattice Boltzmann method is further developed to incorporate the effects of multi-component evaporation.
Journal ArticleDOI
Influence of the fabrication process on the functionality of piezoceramic patch transducers embedded in aluminum die castings
