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.
A device for selective laser sintering of metallic substances which is provided with a construction volume in a process chamber, said construction volume being provided below a floor area of said process chamber and being delimited for building up a component (9) by side walls (2) and a construction platform (3), which is adjustable in height, and said device is provided with a leveling unit for spreading a powdered substance as a layer of constant thickness over a section of the floor area as well as with a laser optic and a scanning unit for scanning a region of the floor area with a laser beam, wherein
A method for selective laser sintering of metallic substances in a process chamber having a construction volume, which is delimited by side walls (2) and by a construction platform (3), which is adjustable in height, for building up a component (9), with said component (9) being built up by means of repeated application of a layer of a powdered substance and sintering, using a laser beam, said layer onto a substrate plate (8), which lies on said construction platform (3) at a distance from said side walls (2), wherein
