Patent ID: 11951677

Abstract:
A three dimensional manufactured product is manufactured A speed of filing an uncured light curing resin in a space for a next layer is enhanced, to improve a manufacturing speed. One surface of a container housing a light curing resin is configured by a gas-permeable sheet that faces the light curing resin, and transmits irradiation light of a light irradiating apparatus, and a light transmitting plate disposed at an outer side of the container from the gas permeable member. A pressurizing chamber controllable in pressure by a pressure controlling apparatus is defined between the gas-permeable sheet and the light transmitting plate. At moving a manufacturing stage, an inside of the pressurizing chamber is de-pressurized to cause the gas-permeable sheet to perform concave surface deformation, and at a time of performing light irradiation, gas in the pressurizing chamber is caused to permeate into the light curing resin by pressurizing.
