Title:
3D MOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/062696
Kind Code:
A1
Abstract:
This 3D molding device (1) comprises a laser light source (21), a diffractive optical modulator (23) having a plurality of modulating elements, a lighting optical system (22), a first projection optical system (241) forming an intermediate image of the optical modulator (23), a second projection optical system (242) for forming a projection image of the intermediate image on a projection surface (95) of a modeling material (91) constituting a processing region, and a layer forming mechanism (12). The second projection optical system (242) scans the projection image on the projection surface (95). The layer forming mechanism (12) forms a new material layer (92) on the projection surface (95) onto which the projection image was scanned to form a new projection surface (95). The projection magnification of the first projection optical system (241) is smaller than the projection magnification of the second projection optical system (242).
