Title:
PRODUCTION APPARATUS FOR THREE-DIMENSIONAL MOLDINGS AND PRODUCTION METHOD FOR THREE-DIMENSIONAL MOLDINGS
Document Type and Number:
WIPO Patent Application WO/2020/194876
Kind Code:
A1
Abstract:
A production apparatus (100) for three-dimensional moldings produces three-dimensional moldings in a prescribed molding space comprising multiple unit spaces. The production apparatus (100) three-dimensional moldings is provided with a beam irradiation unit (40) and a control device (20). The beam irradiation unit (40) irradiates a beam (L32) on a molding material. The control device (20) controls the beam irradiation unit (40). The beam irradiation unit (40) is capable of guiding beams (L32) with differing intensities to at least two unit spaces among the multiple unit spaces. The control device (20) comprises an irradiation control unit (21) for controlling the beam irradiation unit (40) so as to irradiate beams (L32), which have intensity distributions prepared on the basis of flow information, on the molding material. When at least two unit spaces adjoin each other, the flow information comprises information representing flow of the molding material between the at least two unit spaces.
