METHOD AND DEVICE FOR THE SELECTIVE LASER SINTERING OF METALLIC SUBSTANCES

摘要

The present invention relates to a device and a method for the selective laser sintering of metallic substances. The construction volume of the device is delimited by side walls (2) and by a construction platform (3), which is adjustable in height, for building up a component (9). A heating plate (5) is placed on the construction platform (3) at a distance from the side walls (2) or is integrated in the surface of the construction platform (3). The heating plate (5) is designed and thermally insulated from the construction platform (3) by an insulation layer (4) in such a manner that it reaches temperatures of at least 500° C. during heating operation. With the device and the corresponding method, metallic components are maintained at temperatures above 500° C. during the building up process thereby reducing the danger of tensions or cracking in the component.
