Description
Die Erfindung betrifft Einrichtungen zur Herstellung wenigstens eines Metallkörpers mittels 3D-Druck mit wenigstens einem Laser, einer Materialzufuhreinrichtung und einer Bauplattform.The invention relates to devices for producing at least one metal body by means of 3D printing with at least one laser, a material feed device and a construction platform.
Ein 3D-Druck ist bekannterweise ein Fertigungsverfahren, wobei Material schichtweise aufgetragen und beispielsweise durch bereichsweises Schmelzen der Schicht dreidimensionale Körper hergestellt werden.As is known, 3D printing is a manufacturing process in which material is applied in layers and, for example, three-dimensional bodies are produced by melting the layer in areas.

Der im Schutzanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, große und schwere Metallkörper durch pulverbettbasiertes Lasersintern und/oder Laserschmelzen additiv einfach herzustellen.The invention specified in
Diese Aufgabe wird mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöst.This object is achieved with the features listed in
Die Einrichtungen zur Herstellung wenigstens eines Metallkörpers mittels 3D-Druck mit wenigstens einem Laser, einer Materialzufuhreinrichtung und einer Bauplattform zeichnen sich insbesondere dadurch aus, dass schwere Metallkörper durch pulverbettbasiertes Lasersintern und/oder Laserschmelzen additiv einfach herstellbar sind.The devices for producing at least one metal body by means of 3D printing with at least one laser, a material feed device and a construction platform are characterized in particular by the fact that heavy metal bodies can be easily produced additively by powder bed-based laser sintering and / or laser melting.
Dazu ist die Bauplattform ein Boden eines Behälters zur Aufnahme eines in den Behälter in Schichten einzubringenden Pulvers von Metallpartikeln und/oder Metallkörnern. Der Behälter weist wenigstens eine in ihrer Höhe gegenüber dem Boden veränderbare Wand zur Aufnahme der schichtweise in den Behälter eingebrachten Metallpartikel und/oder Metallkörner auf, wobei die Wand zur Höhenverstellung mit wenigstens einem Antrieb so verbunden ist, dass die Wand wenigstens die jeweilig einzubringende Schicht von Metallpartikeln und/oder Metallkörnern überragt. Der Laserkopf ist in x- und y-Richtung über den Behälter bewegbar. Weiterhin sind der Laserkopf und die Materialzufuhreinrichtung in ihrer Höhe gegenüber dem Boden des Behälters geführt verfahrbar.For this purpose, the building platform is a base of a container for receiving a powder of metal particles and / or metal grains to be introduced into the container in layers. The container has at least one height-adjustable wall for receiving the metal particles and / or metal grains introduced into the container in layers, the wall for height adjustment being connected to at least one drive so that the wall has at least the respective layer of Metal particles and / or metal grains surmounted. The laser head can be moved over the container in the x and y directions. Furthermore, the height of the laser head and the material feed device can be moved in a guided manner relative to the bottom of the container.
Vorteilhafterweise besitzt die Einrichtung zur Herstellung wenigstens eines Metallkörpers einen Behälter zur Aufnahme der schichtweise einzubringenden Metallpartikel und/oder Metallkörner mit einem fest fixierten Boden. Ein ansonsten notwendiger absenkbarer Boden wird vermieden. Damit können große und schwere Metallkörper als Bauteile aus Metall durch pulverbettbasiertes Lasersintern und/oder Laserschmelzen erzeugt werden. Der Boden als Bauplattform verbleibt während der Realisierung des Metallkörpers in seiner Position. So können auch Bauteile mit Dimensionen im Kubikmeterbereich mit mehreren Tonnen an Gewicht realisiert werden. Das Austreten der jeweilig aufzubringenden Schicht der Metallpartikel und/oder Metallkörner wird durch die in ihrer Höhe gegenüber dem Boden veränderbare Wand verhindert. Die Höhenverstellung erfolgt dabei jeweils entsprechend der Dicke der aufzubringenden Schicht. Der Metallkörper wird im Metallpulver und/oder in den Metallkörnern so realisiert, dass dieser von Metallpulver und/oder Metallkörnern umgeben ist. Damit wird die Höhenverstellung der Wand gewährleistet. Gleichzeitig wird verhindert, dass sich Bereiche des Bauteils mit Bereichen der Wand durch Sintern oder Schmelzen verbinden. Bei realisiertem Bauteil befindet sich das Bauteil bis auf die Oberseite im Metallpulver und/oder in den Metallkörnern. Die Metallkörner können dazu auch als Schüttgut schichtweise eingebracht werden.The device for producing at least one metal body advantageously has a container for receiving the metal particles and / or metal grains to be introduced in layers with a firmly fixed base. An otherwise necessary lowerable floor is avoided. This means that large and heavy metal bodies can be produced as metal components by powder bed-based laser sintering and / or laser melting. The floor as a construction platform remains in its position during the realization of the metal body. In this way, components with dimensions in the cubic meter range and weighing several tons can be realized. The exit of the respective layer of metal particles and / or metal grains to be applied is prevented by the wall, which can be changed in height relative to the floor. The height adjustment takes place in each case according to the thickness of the layer to be applied. The metal body is implemented in the metal powder and / or in the metal grains in such a way that it is surrounded by metal powder and / or metal grains. This will adjust the height of the wall guaranteed. At the same time, areas of the component are prevented from joining areas of the wall through sintering or melting. When the component is implemented, the component is located in the metal powder and / or in the metal grains except for the upper side. The metal grains can also be introduced in layers as bulk material.
Der so gewählte apparative Aufbau ermöglicht das Erzeugen sehr großer und schwerer Bauteile aus Metall. Ein derartiger Aufbau ist durch eine Kombination eines oder mehrerer Laser und einfachen Achssystemen zum geführten Verfahren des Laserkopfes und der Materialzufuhreinrichtung einfach zu realisieren. Die Achssysteme können dazu als x-, y- und z-Positioniereinrichtungen ausgeführt sein. Durch eine verschiebbare, eine rollbare oder klappbare Wand wird das Entweichen des Metallpulvers und/oder der Metallkörner verhindert. Zur Realisierung des Bauteils sind bis auf die Wand keine zusätzlichen Zwischenwände notwendig. Das Bauteil wird durch das das Bauteil umgebende Metallpulver und/oder die das Bauteil umgebenden Metallkörner in seiner Position gehalten.The apparatus structure selected in this way enables very large and heavy components to be produced from metal. Such a structure can be easily implemented by combining one or more lasers and simple axis systems for the guided movement of the laser head and the material feed device. For this purpose, the axis systems can be designed as x, y and z positioning devices. The escape of the metal powder and / or the metal grains is prevented by a movable, rollable or foldable wall. Apart from the wall, no additional partition walls are necessary to implement the component. The component is held in its position by the metal powder surrounding the component and / or the metal grains surrounding the component.
Zur Höhenverstellung der Wand und zu den Bewegungen des Laserkopfes können die jeweiligen Antriebe mit einer Steuereinrichtung verbunden sein, welche insbesondere ein Datenverarbeitungssystem sein kann. Während der Realisierung des Bauteils als Metallkörper werden die Wand, der Laserkopf und die Materialzufuhreinrichtung in Baurichtung des Bauteils bewegt.To adjust the height of the wall and to move the laser head, the respective drives can be connected to a control device, which can in particular be a data processing system. During the realization of the component as a metal body, the wall, the laser head and the material feed device are moved in the construction direction of the component.
Der Laser oder mehrere Laser kann/können Laserstrahlführungskomponenten entweder in Form einer Glasfaser/Glasfasern oder wenigstens einem Spiegel aufweisen. Weiterhin kann wenigstens eine Fokussiereinrichtung vorhanden sein. Eine Lasereinheit zur Bestrahlung des Metallpulvers und/oder der Metallkörner kann einen oder mehrere Laserstrahlengänge enthalten und mittels jeweils einer Fokussieroptik pro Strahlengang einen überlagernden Brennfleck hoher Leistung erzeugen. Hierdurch können hohe Leistungen beispielsweise durch Kombination mehrerer Laser und damit mehrerer Laserstrahlen eingesetzt werden, um die Effizienz der Herstellung des Bauteils durch den Einsatz ökonomisch günstiger Laser trotz hoher mittlerer Leistung zu steigern.The laser or a plurality of lasers can have laser beam guidance components either in the form of a glass fiber / glass fibers or at least one mirror. Furthermore, at least one focusing device can be present. A laser unit for irradiating the metal powder and / or the metal grains can contain one or more laser beam paths and, by means of one focusing optics per beam path, can generate a superimposed focal point of high power. In this way, high powers can be used, for example by combining several lasers and thus several laser beams, in order to increase the efficiency of the production of the component through the use of economically favorable lasers despite high average power.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Schutzansprüchen 2 bis 9 angegeben.Advantageous configurations of the invention are specified in claims 2 to 9.
Die Einrichtung kann vorteilhafterweise eine parallel zum Boden führbare Rakel zur Verteilung der als Pulver eingebrachten Metallpartikel und/oder der als Schüttgut eingebrachten Metallkörner aufweisen. Diese ist mit einer Antriebsvorrichtung zum Führen der Rakel über die Oberfläche der in den Behälter eingebrachten Metallpartikel und/oder Metallkörner und zur Höhenverstellung der Rakel gegenüber dem Boden des Behälters verbunden.The device can advantageously have a doctor blade which can be guided parallel to the floor for distributing the metal particles introduced as powder and / or the metal grains introduced as bulk material. This is connected to a drive device for guiding the doctor blade over the surface of the metal particles and / or metal grains introduced into the container and for adjusting the height of the doctor blade relative to the bottom of the container.
Der Boden kann in einer Ausführungsform mit einer Heizeinrichtung und/oder Kühleinrichtung verbunden sein.In one embodiment, the base can be connected to a heating device and / or cooling device.
Der Laserkopf kann mit einer Antriebsvorrichtung so verbunden sein, dass die Rakel und der Laserkopf zusammen in ihrer Höhe gegenüber dem Boden geführt verfahren werden.The laser head can be connected to a drive device in such a way that the doctor blade and the laser head are moved together in their height relative to the floor.
Der Laserkopf kann in einer Ausführungsform beabstandet zu einer Rotationsachse angeordnet sein. Weiterhin ist dieser Laserkopf mit einem Rotationsantrieb so verbunden, dass der Laserkopf um die Rotationsachse rotiert. Damit können die Laserstrahlen in einer gewissen Vorzugsrichtung beispielsweise als Linie überlagert werden, so dass sich eine längere Wechselwirkungszeit der Laserstrahlung mit dem Metallpulver und/oder der Metallkörner ergibt. Hierzu verfügt der Laserkopf über die Rotationsachse, um diagonale Fahrten über das Metallpulverbett und/oder das Metallkörnerbett entlang einer frei wählbaren Vorzugsrichtung zu ermöglichen.In one embodiment, the laser head can be arranged at a distance from an axis of rotation. Furthermore, this laser head is connected to a rotary drive so that the laser head rotates around the axis of rotation. The laser beams can thus be superimposed in a certain preferred direction, for example as a line, so that a longer interaction time of the laser radiation with the metal powder and / or the metal grains results. For this purpose, the laser head has the axis of rotation to enable diagonal journeys over the metal powder bed and / or the metal grain bed along a freely selectable preferred direction.
Die Wand des Behälters kann insbesondere eine verschiebbare, eine aufrollbare oder klappbare Wand sein. Eine klappbare Wand kann so mehrere Segmente aufweisen, die gelenkig miteinander verbunden sein können, so dass diese auf- und zusammenklappbar ist.The wall of the container can, in particular, be a movable, rollable or foldable wall. A foldable wall can thus have several segments which can be articulated to one another so that it can be opened and collapsed.
Die Wand kann aus Segmenten bestehen, die einzeln oder zusammen in ihrer Höhe verstellbar sind.The wall can consist of segments that are individually or collectively adjustable in height.
Die Materialzufuhreinrichtung kann insbesondere eine Breitstrahldüse sein, welche über eine Fördereinrichtung mit einem Reservoir von Metallpartikeln und/oder Metallkörnern verbunden ist.The material feed device can in particular be a wide jet nozzle which is connected to a reservoir of metal particles and / or metal grains via a conveying device.
Die Einrichtung kann in einer Ausführungsform wenigstens eine Fräseinheit, eine Schleifeinheit und/oder eine Poliereinheit besitzen. Die Fräseinheit, die Schleifeinheit und/oder die Poliereinheit ist mit einer x-, y- und z-Positioniereinrichtung verbunden, so dass die Fräseinheit, die Schleifeinheit und/oder die Poliereinheit in einer Ebene parallel und in der Höhe gegenüber dem Metallkörper geführt verfahrbar ist. Damit kann eine Insitu-Nachbearbeitung der erzeugten Sinterspuren und/oder Schmelzspuren erfolgen.In one embodiment, the device can have at least one milling unit, one grinding unit and / or one polishing unit. The milling unit, the grinding unit and / or the polishing unit is connected to an x-, y- and z-positioning device so that the milling unit, the grinding unit and / or the polishing unit can be moved in a plane parallel and in height relative to the metal body . In this way, the sintering traces and / or melting traces produced can be reworked in situ.
