Today's manufacturing processes are pushed to their limits to generate products with ever-
increasing quality at low costs. A prominent hurdle on this path arises from the multiscale …

Abstract Metal three-dimensional (3D) printing includes a vast number of operation and
material parameters with complex dependencies, which significantly complicates process …

Dimensionless numbers and scaling laws provide elegant insights into the characteristic
properties of physical systems. Classical dimensional analysis and similitude theory fail to …

Understanding the densification behaviours and formation mechanisms of defects are
essential to fabricate high quality and high strength aluminium components using selective …

The selection of appropriate process parameters is crucial in metal additive manufacturing
(AM) as it directly influences the defect formation and microstructure of the printed part. Over …

Structural defects such as porosity have detrimental effects on additively manufactured parts
which can be reduced by choosing optimal process conditions. In this work, the relationship …

We present a semi-coupled resolved Computational Fluid Dynamics (CFD) and Discrete
Element Method (DEM) to simulate a class of granular media problems that involve thermal …

Understanding and controlling the thermal behavior during laser powder bed fusion (LPBF)
additive manufacturing (AM) is crucial to improve the quality of the printed layer and the …

Laser butt welding (LBW) with high quality is widely sought-after, but results in non-
negligible carbon emission (CE). However, predicting bead geometry and CE of LBW is …

One of the main challenges facing selective laser melting processes is finding suitable
process parameters to achieve maximum density (pore-free) parts. In this letter, two newly …
