Abstract:
1. A device for the layer-by-layer manufacture of a three-dimensional object in a generative process, comprising: a processing chamber, in which the three-dimensional object is gradually formed; a layer-by-layer application mechanism for applying material, onto a target surface in the processing chamber and fusing material layers of the three-dimensional object to be formed; and at least one electromagnetic element for emitting electromagnetic radiation in the processing chamber and/or receiving electromagnetic radiation from the processing chamber, wherein the device includes a temperature moderated fluid film generation mechanism which generates a temperature moderated and/or flow controlled fluid film out of the temperature-moderated fluid between the electromagnetic element and processing chamber volume, wherein the temperature-moderated fluid film generation mechanism includes a fluid source, a fluid line leading the fluid from the fluid source to the process chamber, a heating device configured to heat the fluid flowing through the fluid line, and a blow cap coupled to the electromagnetic element so that the temperature-moderated fluid flows around the electromagnetic element.
