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.

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.

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.
