Abstract: Disclosed is a method for supervision of an additive manufacturing process for producing a manufacturing product by selectively solidifying build-up material in a process chamber. The build-up material is irradiated according to predefinable irradiation control data; and a process chamber supervisory data set is generated based on the irradiation control data, supervisory data being encoded process chamber point by process chamber point in said data set. Quality data concerning the manufacturing process are determined based on the process chamber supervisory data set. A description is further given of a supervisory device suitable therefor a control device for an apparatus for additive manufacturing of manufacturing products, and an apparatus for additive manufacturing of manufacturing products comprising such a control device.

Abstract: A calibration device (30) for an apparatus (1) for layerwise production of a three-dimensional object (2) by layerwise solidification of building material (10) at the locations corresponding to the cross section of the object to be produced in the respective layer by means of at least two energy beams (14a, 14b) includes a housing (31) and a sensor (32) which is arranged in the housing. The sensor serves to receive the at least two energy beams and to output an output signal as a function of the intensity of the energy beams. The housing has at least two through-openings (34a, 34b) for transmitting the at least two energy beams, which are arranged so that their central axes intersect on a surface of the sensor.
Abstract: A method for producing a three-dimensional object (2) by applying layers of a pulverulent construction material (11) and by selectively solidifying said material by the action of energy comprises the steps: a layer of the pulverulent construction material (11) is applied to a support (6) or to a layer of the construction material that has been previously applied and at least selectively solidified; an energy beam (14) from an energy source (13) sweeps over points on the applied layer corresponding to a cross-section of the object (2) to be produced in order to selectively solidify the pulverulent construction material (11); and a gas flow (18) is guided in a main flow direction (RG) over the applied layer during the sweep of the energy beam (14). The main flow direction (RG) of the gas flow (G) and the sweep direction (RL) of the energy beam (14) are adapted to one another at least in one region of the cross-section to be solidified.

Abstract: An exposure control device serves for equipping and/or retrofitting a generative layer-wise building device. The exposure control device has a first data output interface, at which control commands can be output to the exposure device. The control commands specify one of a plurality of exposure types defined by a predetermined combination of a radiation energy density to be emitted by the exposure device and a scanning pattern with which the radiation is being directed to a region of a layer of the building material. The exposure control device also includes a second data output interface at which an exposure type can be output in real time in relation to a timing of the output of a control command specifying this exposure type.

Abstract: Disclosed is a method of determining a quality indicator of an object that has been manufactured by layer-wise additive manufacturing . The method includes providing a first dataset that is assigned to a process monitoring device, detecting a relative frequency of occurrence of a process irregularity in a layer and of assigning a grade indicator value to the solidified object cross-section in a layer according to the detected relative frequency, generating a second dataset, in which a grade indicator value is assigned to the object cross-section in each of said several layers following upon one another, and determining a quality indicator by using the second dataset (or several further datasets).

Abstract: An object build area is exposed to a radiation beam, such as a laser light source, which has been processed and controlled through a grating light valve or valves, or planar light valve, to thereby melt, sinter, fuse or cure predetermined portions of the build area corresponding to the equivalent of individually controlled pixels, with rapid movement and positioning of the resulting LV application output array on the build area. The LV arrangement is adapted to also generally heat an entire powder bed, or targeted areas of the bed, to just below melting temperature.
