TL;DR: Numerical simulations are used in this work to investigate aspects of microstructure and microseg-regation during rapid solidification of a Ni-based superalloy in a laser powder bed fusion additive manufacturing process.

TL;DR: In this article, a laser powder bed fusion system is used to optimize surface roughness in overhanging structures, and a relationship between process parameters, angle of the overhang surface, and surface Roughness metrics such as Rpc, Rsm, and Rc are analyzed.

TL;DR: In this article, the effects of process parameters and scan strategy on the relative density, melt pool size and shape were investigated for powder material nickel-based alloy 625, which is one of the choice of metal materials for fabricating components in jet engines and gas turbines due to its high strength at elevated temperatures.

TL;DR: This paper presents a literature review on the current AM control schemes, process measurements and modelling and simulation methods as it applies to the powder bed fusion process, though results from other processes are reviewed where applicable.

TL;DR: The design, execution, and results of high speed, high magnification in-situ thermographic measurements conducted at the National Institute of Standards and Technology (NIST) focusing on the melt pool region of a commercial L-PBF process are detailed.
