TL;DR: In this paper, the state of the art of additive manufacturing (AM) at the micro-scale level is reviewed, including powder recoating, laser optics, and powder particle size.

TL;DR: In this paper, the ABAQUS AM module is employed to simulate two important metal additive manufacturing processes: (a) Laser Direct Energy Deposition (LDED) and (b) Selective Laser Melting (SLM).

TL;DR: This study has achieved a highly ionic conductive NZSP only by facile addition of Na2SiO3 into the NZSP powder prior to sintering stage, which contributes to the increment of the bulk ion conductivity.

TL;DR: In this article, the acoustic absorption property of nickel-based superalloy open-cell foams manufactured by a newly developed template replication process was investigated, and the results showed that foam samples with the smallest cell size exhibited the best acoustic absorption performance, with sound absorption coefficient < 0.9 at frequencies > 1500 Hz for 50mm thick sample.

TL;DR: In this article, an optimized buffer technique was employed by optimizing targeted critical parameters of the buffer pellet, including the choice of buffer particle composition and its aspect ratio, for the reliable fabrication of large, single grains of (RE)BCO.
