TL;DR: In this paper, the chemical and structural changes of modern and fossil Cervus elaphus enamels were characterized in order to study the chemical changes during fossilization, and a good positive correlation has been found between a cell parameter and C 0 3 2− contents.

10 Jun 2016TL;DR: In this paper, the authors proposed a system for multiple beam additive manufacturing (MAM) where multiple beams of light (e.g., laser light) simultaneously expose layers of powder material in selected regions until the powder material fuses to form voxels, which form build layers of a three-dimensional structure.
Abstract: Systems and methods for multiple beam additive manufacturing use multiple beams of light (e.g., laser light) simultaneously to expose layers of powder material in selected regions until the powder material fuses to form voxels, which form build layers of a three-dimensional structure. The light may be generated from selected light sources and coupled into an array of optical fibers having output ends arranged in an optical head such that the multiple beams are directed by the optical head to different locations on each of the powder layers. The multiple beams may provide distributed exposures forming a distributed exposure pattern including beam spots that are spaced sufficiently to separate the fused regions formed by each exposure. The multiple beams may be moved using various techniques (e.g., by moving the optical head) and according to various scan patterns such that a plurality of multiple beam distributed exposures form each build layer.
