Patent attributes
A method for producing three-dimensional components by successively solidifying layers of a powder construction material solidified by means of electromagnetic radiation, in particular bundled radiation such as laser radiation or electron radiation, at the locations corresponding to the respective cross-section of the component, in particular SLM or SLS. A device comprising a support device, the height of which can be adjusted within a construction chamber, is provided for supporting the component including a coating device for applying layers of the construction material onto the support device or onto a previously formed layer and comprising an irradiating device for irradiating layers of the construction material in some regions to solidify layers. A surface section to be coated is scanned with respect to the evenness of the section prior to the application of a new layer. In the event of an unevenness exceeding a known tolerance range, the unevenness is removed or leveled out.
