Title:
三次元造形装置、及び、三次元造形物の製造方法
Document Type and Number:
Japanese Patent JP7428064
Kind Code:
B2
Abstract:
A three-dimensional shaping apparatus includes a plasticizing section that includes a drive motor, a heater, and a screw rotated by the drive motor and that plasticizes a material to form a shaping material, an ejection section that ejects the shaping material toward a stage, a moving mechanism section that changes a relative position of the ejection section to the stage, a prediction section that predicts a residual service life of the heater from an observation result of a state observation section that observes a state of the heater, and a control unit that controls the plasticizing section and the moving mechanism section to shape a three-dimensional shaped article. The control unit has a first mode in which a temperature of the heater is set to a first temperature and a second mode in which the temperature of the heater is set to a temperature lower than the first temperature, and shapes the three-dimensional shaped article in the first mode when a first residual service life when the temperature of the heater is set to the first temperature exceeds a first value, and shapes the three-dimensional shaped article in the second mode when the first residual service life is equal to or less than the first value.
