Abstract

The invention provides an apparatus (1) for additively manufacturing of three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of build material (3) which can be consolidated by means of an energy beam (4), the apparatus (1) comprising: at least one build plate (5), the build plate (5) being moveably supported in at least one degree of freedom of motion; and / or at least one build material application element (7, 7a, 7b), particularly a coating element, the build material application element (7, 7a, 7b) being moveably supported; at leastone optical device (16), the optical device (16) being adapted to optically determine the orientation and / or position of the build plate (5) and / or the build material application element (7, 7a, 7b)relative to a reference plane (RP).

Description

technical field [0001] The invention relates to a device for the additive production of three-dimensional objects by selectively irradiating and curing layers of a construction material curable by means of an energy beam by selectively irradiating and curing layers one after the other. Background technique [0002] Corresponding devices for the additive production of three-dimensional objects, such as technical structural parts, are widely known and can be implemented, for example, as selective laser sintering devices, selective laser melting devices or selective electron beam melting devices. [0003] A corresponding device includes several functional devices that need to undergo a calibration process. Examples of corresponding functional devices are building plates which are movably supported in at least one degree of freedom of movement, and building material application elements which are movably supported in at least one degree of freedom of movement, in particular coat...
