Additive Manufacturing of Two-Dimensional nanosheet networks for miniaturized structures

ROBCAST或直接墨迹写入，是一种可扩展的添加剂制造技术，它带来了制造三维(3D)几何形状的微型化设备的可能性。三维小型化对于未来的芯片技术非常有吸引力，因为在这些技术中，效率需要在较小的占地面积上进行优化。这是一个新的挑战，因为设备小型化主要是为了实现平面几何图形。该博士项目的目标是研制可印刷的高度浓缩的水基2D原子稀薄材料墨水，并制造新型微型化建筑。油墨由原子薄的三元合金材料组成，这些材料要么从块状材料中剥离，要么通过在溶液中直接合成而获得。通过调整配方油墨的流变性，将实现剪切稀释性，从而实现印刷适宜性并确保印刷结构的机械完整性

Robocasting or Direct Ink Writing, is a scalable additive manufacturing technique that brings the possibility of making minaturized devices in three-dimensional (3D) geometry. Miniaturization over three-dimensional is very attractive for future on-chip technologies where efficiencies need to be optimized over small footprints. This is a new challenge, as device miniaturization is mainly developed to achieve planar-geometries. The objective if this PhD project is to formulate highly concentrated, water-based 2D atomically thin material inks which are printable and to fabricate novel miniaturized architectures. The inks are composed by atomically thin sheets of ternary alloy materials either exfoliated from bulk or obtained via direct synthesis in solution. By tailoring the rheology of the formulated inks, a shear thinning behaviour will be achieved allowing printability and assuring mechanical integrity of our printed structures
