Abstract

The invention relates to a method for operating at least one device (1) for the additive manufacturing of three-dimensional objects (2) by selectively irradiating and curing layers of building material sequentially layer by layer, wherein the layers of building material are composed of energy Consisting of a powdery construction material (3) solidified by means of an energy beam (4), wherein waste heat energy (WTE) is generated during operation of the at least one plant (1), characterized in that the waste heat energy (WTE) is at least Partly used to generate electrical energy (EE) or mechanical energy (ME) by at least one energy conversion device (15), and / or said waste thermal energy (WTE) is used at least partly to operate at least one thermal energy consumer.

Description

Technical field [0001] The present invention relates to a method of operating at least one to add a device for manufacturing a three-dimensional object by sequentially selectively irradiating and curing a layer of powder construction material that can be cured by the energy bundle, wherein at least one for adding Waste thermal energy is generated during operation of the equipment of the three-dimensional object. Background technique [0002] It is well known to adding a three-dimensional object to a powder-shaped apparatus layer to which the energy bundle (e.g., electron beam or laser beam) cured by selectively illuminate and the curing of the energy bundle (e.g., electron beam or laser beam) can be well known. Such devices and methods are used, for example, in the selective laser sintering process, selective laser melting process or selective electron beam melting process. [0003] It is also known to generate waste heat energy during the operation of the corresponding device an...
