Manufacturing method and the microscopic three-dimensional structure of microscopic three-dimensional structure by laser irradiation

摘要

PPROBLEM TO BE SOLVED: To provide a manufacturing method of a minute three-dimensional structure due to the irradiation with a laser capable of simply and inexpensively manufacturing the minute three-dimensional structure on a thermoplastic material, and to provide the minute three-dimensional structure. PSOLUTION: A liquid 2 through which the laser transmits is arranged on the thermoplastic material 1 and the thermoplastic material 1 is continuously irradiated with the laser through the liquid 2 not only to fluidize the thermoplastic material 1 of the laser irradiated part to grow the same in the optical axis direction of the laser 3 but also to form a projected structure 1D of the thermoplastic material.
