TL;DR: The approach to metal-based additive manufacturing is applicable to a wide range of alloys and can be implemented using a range of additive machines, and provides a foundation for broad industrial applicability, including where electron-beam melting or directed-energy-deposition techniques are used instead of selective laser melting.

TL;DR: In this article, the Al-Ta system, in which Al3Ta intermetallic compounds are demonstrated to have substantial grain refining capacity, is shown to be reduced relative to pure aluminum by 1000X when tantalum is added at 1 vol%.

TL;DR: In this paper, the dimensional stability and uniformity of additively manufactured silicon-based ceramics as a function of geometry and processing conditions are quantified using x-ray micro-computed tomography (micro-CT).

TL;DR: In this article, a cellular architecture of lattice-based impact attenuators is used to optimize their performance for a typical helmet impact scenario where the contact area increases during deformation.

TL;DR: In this article, the experimental and simulation results for the low-velocity impact response of sandwich panels reinforced with a lattice core structure were presented, and two different core material and architecture combinations were investigated; a UV-cured photopolymer lattice, produced from a network of self-propagating waveguides and an aluminum alloy lattice cast from an initial polymer template.
