Title:
METHOD AND DEVICE FOR CONTROLLING IRRADIATION SYSTEM
Document Type and Number:
Japanese Patent JP2015120340
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for controlling an irradiation system for use in an apparatus in which a three-dimensional work piece is produced.SOLUTION: A method for controlling an irradiation system 20 comprises the steps of: forming a first irradiation area 18a on a surface of a carrier 16 adapted to receive a layer of raw material powder, irradiating the layer of raw material powder applied onto the carrier 16 in the first irradiation area 18a by a first irradiation unit 22a of the irradiation system 20, while controlling the operation of the first irradiation unit 22a in such a manner that the raw material powder is pre-heated, and thereafter irradiating the layer of raw material powder applied onto the carrier 16 in the first irradiation area 18a by a second irradiation unit 22b of the irradiation system 20, while controlling the operation of the second irradiation unit 22b in such a manner that the raw material powder is heated to a temperature which allows sintering and/or melting of the raw material powder to generate a layer of the three-dimensional work piece.
