Abstract: The present invention pertains to: a microneedle having a structure of three or more layers; and a method for manufacturing same. The microneedle has a structure of three or more layers, wherein the structure is a structure including an inner pillar shell, a structure including a three-dimensional structure shell, or a structure including a solid drug.

Abstract: The present invention relates to a tree-shaped microneedle having a layered structure with three or more layers and a manufacturing method therefor, and is a technique relating to a liquid injection-type microneedle or a nanobubble micro.

Abstract: Provided are a microneedle using a laminated manner, a method of manufacturing a microneedle, and a system thereof. The method of manufacturing the microneedle according to an embodiment of the present invention includes extruding a first material using a first nozzle and extruding a second material using a second nozzle, and manufacturing the microneedle through a laminated manner using the extruded first material and second material.
