Title:
加工物の幾何学的形状に依存して照射システムを制御する方法及びデバイス
Document Type and Number:
Japanese Patent JP6548613
Kind Code:
B2
Abstract:
In a method for controlling an irradiation system (20) for use in an apparatus (10) for producing a three-dimensional work piece (28), a first and a second irradiation area (18a, 18b) as well as an overlap area (19) arranged between the first and the second irradiation area (18a) are defined on a surface of a carrier (15) adapted to receive layers (30, 32) of a raw material powder to be irradiated with electromagnetic or particle radiation emitted by the irradiation system (20). A first irradiation unit (22a) of the irradiation system (20) is assigned to the first irradiation area (18a) and the overlap area (19), and a second irradiation unit (22b) of the irradiation system(20) is assigned to the second irradiation area (18a) and the overlap area (19). At least one of the first irradiation area (18a), the second irradiation area (18b) and the overlap area (19) is defined in dependence on a geometry of the three-dimensional work piece (28) to be produced.
