Kind Code:
A1
Abstract:
This shaping device comprises a table, a forming unit that forms a shaped object, and a controller that controls an operation of the forming unit. The table rotates in a rotation direction. The forming unit has a feeder for forming a powder bed, a heater that can pre-heat each of a plurality of regions on the powder bed at different temperatures, and a beam source that irradiates the pre-heated powder bed with an energy beam. The controller includes: a region dividing unit that divides the powder bed into a plurality of small regions; a region setting unit that sets, as a first region, a small region including a planned irradiation section to be irradiated with the energy beam by the beam source, and sets, as a second region, at least one small region among the other regions not set as the first region; and a heater control unit that controls the output of the heater such that the first region and the second region are pre-heated at mutually differing temperatures.
