Patent number: 11679558Abstract: An optical forming device includes a resin tank that is to retain a photocurable resin containing dichroic polymerization initiator and a light emitter to emit light for causing the photocurable resin to undergo curing. An alignment film for causing the dichroic polymerization initiator to align in a predetermined direction is provided on a bottom portion of the resin tank. The light emitter irradiates the photocurable resin with the light by passing the light through the bottom portion of the resin tank as linearly polarized light having a polarization direction in a direction perpendicular to a direction in which the dichroic polymerization initiator is aligned by the alignment film.Type: GrantFiled: December 4, 2020Date of Patent: June 20, 2023Assignee: TIANMA JAPAN, LTDInventor: Chikaaki Mizokuchi
