Title:
STEREOLITHOGRAPHY APPARATUS, STEREOLITHOGRAPHY PROGRAM, AND STEREOLITHOGRAPHY METHOD
Document Type and Number:
WIPO Patent Application WO/2019/124526
Kind Code:
A1
Abstract:
In the stereolithography apparatus according to the present invention, a measurement unit measures the temperature of a photocurable liquid resin by means of a temperature sensor. A setting unit sets an integrated light amount on the basis of temperature information obtained from the measured temperature and curing information stored in a storage unit, and a radiation unit controls a projector such that the photocurable liquid resin is irradiated with light with which the set integrated light amount can be obtained. As a result, the photocurable liquid resin is irradiated with light of the integrated light amount that corresponds to the temperature of the photocurable liquid resin, thereby enabling a molded object to be molded with high precision.
