This paper reports on the proposal and implementation of a method for fabricating hydrogel structures using a micro 3D printing system equipped with a precision leveling mechanism by thermal imprinting. Creating functional 3D microstructures such as sensors and actuators at the microscale is expected to contribute to the advancement of cell manipulation and cell culture systems. However, conventional 3D printing techniques have faced difficulties in controlling the gap between the building plate and the bottom of the substrate. A thermoplastic resin was used on the bottom surface of a 3D printer, and the surface shape of the building plate was transferred to the bottom surface to achieve a uniform distance between the two. With this method, the gradient of the height of the fabricated object within a 2mm square improved from 0.63°/mm in the x-direction and 1.03°/mm in the y-direction without thermal imprinting to 0.35°/mm in the x-direction and 0.31°/mm in the y-direction with thermal imprinting.
