Document Type and Number:
Japanese Patent JP7446874
Kind Code:
B2
Abstract:
A powder supply device that supplies metal powder 2 to a modeling surface 4, laser systems 30 and 40 that melt the metal powder 2 at a predetermined position in the metal powder 2 supplied to the modeling surface 4, first thermometers 36 and 46 and a second thermometer 50 that measure a temperature change in each region of the modeling surface 4, and a control device 70 that controls the laser systems 30 and 40 are provided. The control device 70 determines a laser irradiation condition for a next layer, based on the temperature change after beam irradiation of the modeling surface 4. Thus, there are provided an additive modeling apparatus and a method of controlling the additive modeling apparatus capable of making the modeling quality of the entire modeled object uniform regardless of the shape of the modeled object.
