▎ 摘　　要

NOVELTY - Manufacturing of three-dimensional graphene involves placing a substrate plane on a Z-axis worktable of a selective laser melting ink printing metal nano-particle forming device, adjusting the Z- axis moving platform to a laser focal position. The copper micro-nano dispersing solution is placed into a copper micron dispersion solution supply system, opening the coating process by using the control system of the device, uniformly coat the copper micropowder on the surface of the substrate by the spreading cutter, forming the oil paint film with stable surface, ensure that the copper nickel dispersion liquid ink is fully wetted on the substrate. The laser technique parameter is settled, and laser scanning under the control of the upper computer, scan and manufacture the copper/amorphous carbon three-layer structure layer by layer, performing high temperature annealing treatment. USE - Method for manufacturing three-dimensional graphene by laser additive of copper micro-nano powder mixed solution. Uses include but are not limited to electronic component, biological medical treatment, and sensor. ADVANTAGE - The method combines laser-induced and selective laser melting technology advantages, using laser 3D printing technology to prepare metal supporting framework, at the same time as catalyst, adding suitable carbon source, laser induced in situ generating three-dimensional porous graphene.
