Document Type and Number:
WIPO Patent Application WO/2019/155933
Kind Code:
A1
Abstract:
Provided is a stereolithography device that can be used with various forming materials, and a manufacturing method for a formed object. A stereolithography device according to the present embodiment comprises: a laser source (11) that emits a laser beam (L1) having a wavelength of (510n)m or less; an objective lens (17) that focuses the laser beam (L1) on a forming material (21); and a scanner (13) that changes the focal position of the laser beam (L1) on the forming material (21). As a result of two-photon absorption of the laser beam (L1) having a wavelength of (510n)m or less, the forming material (21) is cured, thereby forming an object (22).
