Abstract
The present invention relates to a method and a device for selective laser sintering in which powder is introduced in layers into a jacketed design space, forming a powder cake which is consolidated layerwise by laser radiation. The design space is encircled and heated by a jacket heating device.
Claims4
A method for selective laser sintering of a powder in which the powder is introduced in layers into a space of a jacket, forming a powder cake, the method comprising:
- heating the jacket so that a temperature distribution develops in the jacket, the temperature in the jacket decreasing in the direction of a bottom of the jacket design space, starting from regions of the jacket bordering the last sintered surface of the powder cake.
