Title:
THREE-DIMENSIONAL MODELING METHOD, AND THREE-DIMENSIONAL MODELING APPARATUS
Document Type and Number:
Japanese Patent JP2021120201
Kind Code:
A
Abstract:
To appropriately control energy input amount to reduce performance variation of a plurality of modeled objects in a 3D modeling that simultaneously forms the plurality of modeled objects.SOLUTION: An irradiation area of a laser beam corresponding to each of shapes of a plurality of modeled objects 1103 and 1203 is determined. The irradiation area corresponding to each of the plurality of modeled objects is divided into a plurality of partial irradiation areas each corresponding to a specific portion of the plurality of modeled objects 1103 and 1203. An irradiation order of the laser beam to the plurality of partial irradiation areas each corresponding to the respective plurality of modeled objects 1104 and 1204 is determined so as to be the same among the plurality of modeled objects. Then, by the determined irradiation order, and after the laser beam is irradiated to the partial irradiation area corresponding to the specific portion of one modeled object 1104, the laser beam is continuously irradiated to the partial irradiation area corresponding to the same specific portion of the other modeled object 1204.SELECTED DRAWING: Figure 7
