“…In recent years, laser three-dimensional (3D) printing has rapidly developed into a key strategic technology for technological innovation and industrial sustainability owing to its unparalleled advantage in one-step integral fabrication of end-use components with complex shapes [10][11][12][13]. In the field of oxide eutectic ceramic manufacturing, studies on laser 3D printing have sprung up in the past decade for the purpose of developing new solidification technique to prepare complex-structured eutectic parts [14][15][16][17][18][19][20][21][22].…”

“…The S YY stress is not presented because it does not change with laser scanning pattern and provides smaller contributions to the stress state. This is due to plate theory, which states that only limited load can be supported through the thickness direction in thin wall structures, as shown in (Chakraborty et al, 2021). Note that the inconsistency in the stress distribution around the center line is due to the mesh-to-mesh mapping, as shown in (Hajializadeh and Ince 2019).…”

“…The difference is approximately 3 times higher for the short vector length. This increase in compressive residual stress will negatively impact the limiting build height in thin-wall components, as observed in (Chakraborty et al, 2021).…”

“…A significant insight from Baumers et al (2017b) is that the expected impact of build failure is absent in most investigations on the cost of AM. The existing literature investigating build failure in AM is divided into four categories, including software-based simulation (Bresson et al, 2022;Chakraborty et al, 2022;Ge & Flynn, 2022), design optimization (Misiun et al, 2021;Prabhu et al, 2021;Xu et al, 2022), data-based estimation (Jirandehi et al, 2022;Wang et al, 2021), and mechanism exploration (Osswald et al, 2021;Roh et al, 2021). However, the impact of build failure on the environmental performance of AM, in terms of both process energy consumption and the energy embedded in the used raw materials, has not yet been investigated directly and in combination.…”
