Method and device for selective laser sintering
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.
1. A device for selective laser sintering of a powder comprising:
a jacket having a design space for receiving the powder and a design space bottom, the jacket encircling the design space, and capable of heating different regions of the jacket separately so as to develop a temperature distribution decreasing toward the design space bottom; and
a laser configured to perform selective laser sintering of a top layer of the powder in the design space.
2. The device as recited in claim 1 , wherein the design space has a cylindrical design, the jacket including a heating device including heating rings disposed in parallel one over another and arranged concentrically around the design space.
3. The device as recited in claim 2 , wherein at least one control device-is contained for controlling the individual heating rings separately.
4. The device as recited in claim 3 , wherein the at least one control device features an input unit for entering a temperature distribution to be adjusted via the heating rings.
