TLDR
In this paper, the authors compared the microstructure and tensile properties of Hastelloy X built with low and high power lasers and found that the use of a high power laser results in wider and shallower melt pools inducing an enhanced morphological and crystallographic texture along the building direction.About:

Influence of selective laser melting process parameters on texture evolution in pure copper
Suraj Dinkar Jadhav,Sasan Dadbakhsh,Louca Raphaël Goossens,Jean-Pierre Kruth,J. Van Humbeeck,Kim Vanmeensel +5 more
TL;DR: In this article, the influence of different laser scan parameters such as hatch spacing, laser power and scan speed on the texture evolution in the manufactured parts is determined, which shows that the texture at the top surface can be very strong especially when a high-laser power and low scanning speed is used.

Selective laser melting of pure molybdenum: Evolution of defect and crystallographic texture with process parameters
Masaya Higashi,Tomomichi Ozaki +1 more
TL;DR: In this paper, defect and the crystallographic texture properties of pure Mo bulk samples were investigated in detail with various process parameters, such as laser power, scan speed, and layer thickness, and the effects of each parameter on the microstructure were evaluated individually.

Effect of selective laser melting parameters on morphology, microstructure, densification and mechanical properties of supersaturated silver alloy
TL;DR: In this article, the effects of laser power, scanning speed and scanning strategy on the morphology, microstructure, density and mechanical properties of Ag alloy are described, and the authors seek to determine the optimum solution to this limitation by identifying the most suitable laser device, material and parameters for manufacturing Ag alloy through SLM.

TL;DR: The entire ImageJ codebase was rewrote, engineering a redesigned plugin mechanism intended to facilitate extensibility at every level, with the goal of creating a more powerful tool that continues to serve the existing community while addressing a wider range of scientific requirements.
Journal ArticleDOI
Consolidation phenomena in laser and powder-bed based layered manufacturing
TL;DR: In this article, the authors describe which types of laser-induced consolidation can be applied to what type of material, and demonstrate that although SLS/SLM can process polymers, metals, ceramics and composites, quite some limitations and problems cause the palette of applicable materials still to be limited.
Journal ArticleDOI
Texture and Anisotropy
TL;DR: A review of the literature on preferred orientation of olivine deformation can be found in this paper, where the authors highlight some of the issues with the prevailing view that seismic fast directions align with the flow direction.
