“…Because of the variability in the process and final part properties due to thermal gradients, researchers have modeled the heat transfer within the MatEx process (Pourali and Peterson, 2019; Xia et al , 2018; Nahar and Gurrala, 2022; Driezen and Herrmann, 2022; Duarte et al , 2021) and implemented models to predict the strength of the welds within the process (Coogan and Kazmer, 2020; Peterson and Kazmer, 2022). As part of those efforts, researchers have investigated modeling of the melt temperature within the MatEx hot end (Trofimov et al , 2022; Xia et al , 2018; Osswald et al , 2018; Moretti et al , 2021; Prajapati et al , 2018; Van Waeleghem et al , 2022; Serdeczny et al , 2020b; Kattinger et al , 2022; Go et al , 2017; Mazzei Capote et al , 2021; Luo et al , 2020; Serdeczny et al , 2022).…”
