  • Publication number: 20210178698
    Abstract: A measuring section of a stereolithography device measures a temperature of a photocurable resin liquid by a temperature sensor. A setting section sets an integrated light amount on the basis of temperature information obtained from a measured temperature and curing information stored in a storage section. An illuminating section controls a projector such that light, by which the set integrated light amount is obtained, is illuminated onto the photocurable resin liquid. Due thereto, light, which is such that there becomes an integrated light amount corresponding to the temperature of the photocurable resin liquid, is illuminated onto the photocurable resin liquid, and therefore, a molded object can be molded with high accuracy.
