Abstract: A device is provided, for analyzing sensor data of a sensor arranged in an apparatus for producing a three-dimensional work piece via irradiation of layers of raw material with an energy beam. The device comprises a control unit configured to receive the sensor data as a time series of data values. Each data value is indicative of a process condition within the apparatus during producing the three-dimensional work piece. The control unit is further configured to receive planning data for the three-dimensional work piece. The planning data defines a plurality of scanning vectors and a sequence according to which the energy beam is scanned along the scanning vectors.

Abstract: We describe a process chamber, an apparatus, a modular system, a method, a safety device, a positioning system and a system for producing a three-dimensional workpiece and/or for use thereof when producing a three-dimensional workpiece. The process chamber for producing the three-dimensional workpiece via an additive layer construction method comprises: a material supply unit comprising a substantially ring-like shaped end portion at a first side of the process chamber, wherein the material supply unit is adapted to supply, via the end portion, material to a carrier on which the material is to be processed by the process chamber for producing the three-dimensional workpiece, and an opening at the first side of the process chamber for processing, by the process chamber, the material supplied on the carrier in order to produce the three-dimensional workpiece, wherein the substantially ring-like shaped end portion surrounds the opening.

Abstract: Methods for determining a hazard area between a test object and an X-ray inspection system include arranging a radiation detector at a predetermined distance from a radiation source. Marginal rays are determined which, at a predetermined angle of rotation between the test object and the arranged radiation source and radiation detector, touch an outer contour of the test object at the predetermined angle of rotation. A hazard radius is determined from the outer contour to the rotational axis of the test object for the predetermined angle of rotation. The determination of the marginal rays is repeated for predetermined angles of rotation which are distributed over 360° and the determination of the hazard radius is repeated for each respective repeated determination of marginal rays. A table is compiled with parameters of the hazard radius obtained for each of the predetermined angles of rotation of the edge of the test object.
