Abstract

The invention relates to a method for producing a three-dimensional component by an electron-beam, laser-sintering or laser-melting process, in which the component is created by successively solidifying predetermined portions of individual layers of building material that can be solidified by being exposed to the effect of an electron-beam or laser-beam source (2) by melting on the building material, wherein thermographic data records are recorded during the production of the layers, respectively characterizing a temperature profile of at least certain portions of the respective layer, and the irradiation of the layers takes place by means of an electron beam or laser beam (3), which is controlled on the basis of the recorded thermographic data records in such a way that a largely homogeneous temperature profile is produced, wherein, to irradiate an upper layer, a focal point (4) of the electron beam or laser beam (3) is guided along a scanning path (17), which is chosen on the basis of the data record characterizing the temperature profile of at least certain portions of the layer lying directly thereunder or on the basis of the data records characterizing the temperature profiles of at least certain portions of the layers lying thereunder.

Abstract

An additive manufacturing machine includes an energy beam system configured to emit an energy beam utilized in an additive manufacturing process, and first and second optical elements utilized by, or defining a portion of, the energy beam system and/or an imaging system of the additive manufacturing machine. The imaging system monitors one or more operating parameters of the additive manufacturing process. A light source is configured to emit an assessment beam that follows an optical path incident upon the first and second optical elements. One or more light sensors detect a reflected beam that is either internally reflected by the first optical element or reflectively propagated between the first and second optical elements. A control system determines, based at least in part on assessment data comprising data from the one or more light sensors, whether at least one of the first and second optical elements exhibits an optical anomaly.

Abstract

An irradiation device for an additively manufacturing apparatus may include a working beam generation device configured to provide a working beam, a modulation beam generation device configured to provide a modulation beam, and a solid-state optical modulator that includes a crystalline material that exhibits a change in refractive index in response to photoexcitation of free electrons within the crystalline material. The irradiation device may include a power source coupled to the solid-state optical modulator and configured to introduce free electrons into the crystalline material. The modulation beam may cause photoexcitation of the free electrons within the crystalline material. The photoexcitation of the free electrons within the crystalline material may cause the crystalline material to exhibit a change in refractive index. The working beam, when incident upon the crystalline material, may exhibit a change in one or more parameters, such as a phase shift, attributable at least in part to the change in refractive index exhibited by the crystalline material.

Abstract

Sensor values captured by a sensor device are determined, one or more regions of a three-dimensional component having a deviation from an intended value are determined based at least in part on build coordinates for additively manufacturing the three-dimensional component corresponding to the sensor values, and a quality of the three-dimensional component is evaluated based at least in part on the one or more regions of the three-dimensional component having a deviation from the intended value. The sensor values correspond to an electromagnetic spectrum emitted by a melt pool formed by exposing a powder bed to a beam of radiation emitted from a laser apparatus, with the beam of radiation generating the melt pool in a melt region of the powder bed.

Abstract

A process monitoring system for an additive manufacturing apparatus includes a scanner, a sensor device, and an optical focus-tracking device. The scanner includes an optical adjustment device that directs a melting beam emitted by a laser melting device onto a construction plane to generate a melting section of the construction plane. The sensor device may detect reflected radiation from the melting section and generate sensor data indicative of a size, shape, and/or temperature corresponding to the melting section. The optical focus-tracking device includes a focusing lens located between the scanner and the sensor device. The focusing lens may be actuatable by electronic machine data derived from the sensor data to impart a first focus adjustment with respect to the reflected radiation detected by the sensor followed by a second focus adjustment with respect to the melting beam directed by the optical adjustment device.

Abstract

The invention relates to a method for producing a three-dimensional component by an electron-beam, laser-sintering or laser-melting process, in which the component is created by successively solidifying predetermined portions of individual layers of building material that can be solidified by being exposed to the effect of an electron-beam or laser-beam source (2) by melting on the building material, wherein thermographic data records are recorded during the production of the layers, respectively characterizing a temperature profile of at least certain portions of the respective layer, and the irradiation of the layers takes place by means of an electron beam or laser beam (3), which is controlled on the basis of the recorded thermographic data records in such a way that a largely homogeneous temperature profile is produced, wherein, to irradiate an upper layer, a focal point (4) of the electron beam or laser beam (3) is guided along a scanning path (17), which is chosen on the basis of the data record characterizing the temperature profile of at least certain portions of the layer lying directly thereunder or on the basis of the data records characterizing the temperature profiles of at least certain portions of the layers lying thereunder.

Abstract

Additive manufacturing systems may include a laser melting apparatus, a sensor device, and a visualization apparatus. A laser melting apparatus may form a three-dimensional component by exposing a powder bed to a beam of radiation based on build coordinates, with the beam of radiation providing an energy influx that generates a melt pool in a melt region of the powder bed. A sensor device may capture sensor values corresponding to the melt pool and/or the melt region. A visualization apparatus may display a representation of the three-dimensional component, with the display including the build coordinates and the sensor values in respect of a capture location thereof in the three-dimensional component. The displayed representation may be based on a display output that includes sensor values correlated with build coordinates.

Abstract

A procedure for calibration of at least one scanning system of a laser sinter or laser melt facility can be carried out in a short time, can take place automatically, and thereby can be carried out before each individual construction process. The procedure may include generation of at least one line pattern through at least one scanning system on a surface at the level of a construction field.

Abstract

Powder module (1) for an apparatus for additively manufacturing three-dimensional objects, the powder module (1) comprising a powder chamber (6) having a power chamber volume (7) and a carrying device (9), the carrying device (9) comprising: a carrying unit (8) being moveably supported along a motion axis between a first position, particularly a lower end position, and a second position, particularly an upper end position, relative to the powder chamber (6), a drive unit (10) for generating a drive force for moving the carrying unit (8) between the first position and the second position or vice versa, a coupling unit (11) for coupling the carrying unit (8) with the drive unit (10), and a second extension state, particularly corresponding to the second position of the carrying unit (8), a guiding unit (12) surrounding the coupling unit (11).
