Abstract
Description
Die Erfindung/Neuerung betrifft eine Vorrichtung zur Herstellung dreidimensionaler Objekte durch sukzessives Verfestigen von Schichten eines insbesondere pulverförmigen, mittels elektromagnetischer Strahlung oder Teilchenstrahlung verfestigbaren Aufbaumaterials. Durch die Strahlung wird das Aufbaumaterial an den dem jeweiligen Querschnitt des Objektes entsprechenden Stellen verfestigt. Die Vorrichtung umfasst eine Baukammer, eine darüber angeordnete Prozesskammer und eine darin untergebrachte Vorrichtung zum Aufbringen des Baumaterials, das auf eine höhenverstellbare Plattform in der Baukammer aufgebracht wird und das in einer Dosierkammer bevorratet ist. Über der Baukammer ist eine Bestrahlungseinrichtung zum Bestrahlen der aufgetragenen Schichten des Aufbaumaterials an den Stellen, die verfestigt werden sollen, vorgesehen. Außerdem ist in der Prozesskammer eine Schleifeinrichtung vorgesehen, mit welcher bereits verfestigte Schichtbereiche geglättet werden können.The invention / innovation relates to a device for producing three-dimensional objects by successive solidification of layers of a particular pulverulent build-up material which can be solidified by means of electromagnetic radiation or particle radiation. By the radiation, the building material is solidified at the respective cross-section of the object corresponding locations. The apparatus comprises a building chamber, a process chamber arranged above and a device for applying the building material, which is applied to a height-adjustable platform in the building chamber and which is stored in a metering chamber. Above the building chamber is provided an irradiation device for irradiating the applied layers of the building material at the locations to be solidified. In addition, a grinding device is provided in the process chamber, with which already solidified layer regions can be smoothed.
Eine derartige Vorrichtung geht z. B. aus
Die bekannte Vorrichtung ist insofern nachteilig, als die Schleifvorrichtung fest an die Aufbringvorrichtung gekoppelt ist und sie deswegen relativ räumlich aufwendig baut. Außerdem hat es sich herausgestellt, dass ein Schleifvorgang nicht immer erforderlich ist, sodass bei der bekannten Vorrichtung die Schleifvorrichtung bei jedem Auftrag umsonst über die Baufläche geführt wird.The known device is disadvantageous in that the grinding device is firmly coupled to the applicator and therefore it builds relatively spatially expensive. In addition, it has been found that a grinding operation is not always required, so that in the known device, the grinding device is performed for free on each job over the building area.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit den Merkmalen des Oberbegriffes des Anspruches 1 hinsichtlich seiner Bauform kompakter und seiner Anwendbarkeit flexibler zu gestalten. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The invention has for its object to make a device with the features of the preamble of claim 1 more compact in terms of its design and its applicability more flexible. This object is solved by the characterizing features of claim 1. Advantageous developments emerge from the subclaims.
Nach der Erfindung ist vorgesehen, dass die Vorrichtung zum Aufbringen des Aufbaumaterials, d. h. die Vorrichtung, die das pulverartige Aufbaumaterial von der Dosierkammer in den eigentlichen Baubereich über der Baukammer transportiert und die Schleifvorrichtung zum Glätten bereits verfestigter Schichtbereich, gesonderte Antriebe aufweisen und gesondert in der Prozesskammer verfahren werden können. In Weiterbildung der Erfindung ist es auch möglich, Schleifvorrichtung und Aufbringvorrichtung in ein und demselben Bereich der Prozesskammer in Parallellage zu parken oder z. B. die Schleifvorrichtung auf der einen Seite oder zwischen der Dosierkammer und einem Seitenbereich der Prozesskammer anzuordnen und die Aufbringvorrichtung während des Belichtungsprozesses bereits in eine Warteposition zwischen der Dosierkammer und der Baukammer zu verfahren, nachdem die Aufbringvorrichtung neues Pulvermaterial für den nächsten Beschichtungsvorgang aufgenommen hat. Dadurch kann für den Beschichtungsvorgang Zeit eingespart werden.According to the invention it is provided that the device for applying the building material, d. H. the device which transports the powdery building material from the metering chamber into the actual building area above the building chamber and the grinding device for smoothing already solidified layer area, have separate drives and can be moved separately in the process chamber. In a further development of the invention, it is also possible to park grinding device and applicator in one and the same area of the process chamber in parallel position or z. B. to arrange the grinder on one side or between the metering chamber and a side portion of the process chamber and the applicator already to move during the exposure process in a waiting position between the metering chamber and the building chamber, after the applicator has taken up new powder material for the next coating operation. This can save time for the coating process.
Zunächst ermöglicht die Ausgestaltung der Vorrichtung gemäß der Erfindung in vorteilhafter Weise einen flexibleren Betrieb der Vorrichtung. Z. B. können mehrere unmittelbar nacheinander ablaufende Beschichtungsvorgänge durchgeführt werden, ohne dass die Schleifwalze über die Baufläche geführt werden muss, was unter gewissen Voraussetzungen sinnvoll sein kann. Darüber hinaus kann z. B. durch eine optische Überwachungsvorrichtung festgestellt werden, ob überhaupt ein Schleifvorgang erforderlich ist. Ist dies nicht der Fall, kann eine ausreichend glatte Oberfläche sofort erneut beschichtet werden, ohne zu schleifen. Darüber hinaus ermöglicht es der gesonderte Antrieb der Schleifvorrichtung, die Schleifwälze in unterschiedlichen Höhenlagen mehrfach über die verfestigte Schicht zu führen, sodass ganz dosiert ein Abtrag von unebenen Stellen erfolgen kann. Dazu kann eine Höhenverstellung der Schleifvorrichtung im mehrfachen μm-Bereich vorgesehen werden, die den Schleifvorgang verbessert.First, the embodiment of the device according to the invention advantageously allows a more flexible operation of the device. For example, a plurality of immediately following successive coating operations can be performed without the sanding roller must be guided over the building area, which may be useful under certain conditions. In addition, z. B. be determined by an optical monitoring device, if ever a grinding operation is required. If this is not the case, a sufficiently smooth surface can be recoated immediately without sanding. In addition, the separate drive of the grinding device makes it possible to guide the grinding rolls at different altitudes several times over the solidified layer, so that very dosed removal of uneven spots can take place. For this purpose, a height adjustment of the grinding device in the multiple micron range can be provided, which improves the grinding process.
Schließlich sind die sich gegenüberliegenden oder rechtwinklig zueinander angeordneten Parkpositionen in unterschiedlichen Bereichen der Prozesskammer der Schleifvorrichtung und der Beschichtungsvorrichtung vorteilhaft, weil dann die eine Vorrichtung in geparktem Zustand die gerade arbeitende Vorrichtung nicht stört. Sie ist entweder seitlich von der Verfahrrichtung der anderen Vorrichtung angeordnet oder außerhalb des Verschiebeweges der jeweils anderen Vorrichtung, wenn die Parkpositionen an sich gegenüberliegenden Seitenbereichen der Prozesskammer angeordnet sind.Finally, the opposite or at right angles arranged parking positions in different areas of the process chamber of the grinding device and the coating device are advantageous because then the one device in parked state does not disturb the currently operating device. It is either arranged laterally from the direction of travel of the other device or outside the displacement path of the respective other device, when the parking positions are arranged on opposite side regions of the process chamber.
Besonders vorteilhaft ist es, für die Parkposition der Schleifvorrichtung einen Raumbereich unter einer winkelartig ausgebildeten Aufbringvorrichtung auszunutzen. Dies bedeutet, dass die beiden Parkpositionen von Aufbringvorrichtung und Schleifvorrichtung nur sehr wenig Raum innerhalb der Prozesskammer beanspruchen, was sich z. B. bei Servicearbeiten vorteilhaft auswirken kann.It is particularly advantageous for the parking position of the grinding device to have a spatial area under an angle-like application device exploit. This means that the two parking positions of applicator and grinding device only require very little space within the process chamber, which is z. B. can have an advantageous effect on service work.
Mit Vorteil sind Aufbringvorrichtung und Schleifvorrichtung jeweils durch riemenartige Antriebsmittel gesondert antreibbar, die in Längsausnehmungen der Seitenwandungen der Baukammer motorisch angetrieben umlaufen. Die Ausnehmungen zur Aufnahme der riemenartigen Antriebsmittel der beiden Vorrichtungen können übereinanderliegend, d. h. parallel verlaufend angeordnet sein, wobei für die Aufbringvorrichtung für einen genauen Auftrag des Pulvers ein beidseitiger Antrieb vorteilhaft ist und für die Schleifvorrichtung unter Umständen ein einseitiger Antrieb ausreicht. Die Schleifvorrichtung kann als Schleifwalze ausgebildet sein, die in einem zur Baufläche hin offenen Gehäuse rotierend antreibbar ist. Das Gehäuse ist somit zur Prozesskammer hin abgeschlossen, d. h. Partikel, die von der Schleifwalze mitgerissen werden, werden nicht willkürlich in die Prozesskammer geschleudert, was einer Verunreinigung der Prozesskammer und insbesondere auch der optischen Fenster und dgl. entgegenwirkt.Advantageously, applicator and grinding device are each separately driven by belt-like drive means which rotate in longitudinal recesses of the side walls of the building chamber driven by a motor. The recesses for receiving the belt-like drive means of the two devices can be superimposed, d. H. be arranged running parallel, wherein for the applicator for a precise order of the powder, a double-sided drive is advantageous and may be sufficient for the grinding device a one-sided drive. The grinding device may be formed as a grinding roller, which is rotationally driven in a housing open towards the building surface. The housing is thus closed to the process chamber, d. H. Particles that are entrained by the grinding roller are not randomly thrown into the process chamber, which counteracts contamination of the process chamber and in particular the optical window and the like.
Aufgrund des gesonderten Antriebes ist es auch mit Vorteil möglich, die Schleifvorrichtung mit einer ersten Geschwindigkeit den zu beschleifenden Schichtbereich zuzuführen oder von diesem wegzuführen und mit einer zweiten, vorzugsweise niedrigeren Geschwindigkeit über den zu beschleifenden Schichtbereich zu verfahren. Dadurch werden die für den Schleifvorgang erforderlichen Zeitintervalle abgekürzt. Das Gehäuse der Schleifvorrichtung kann mit einer Absaugeinrichtung versehen sein, die geeignet ist, durch gezielte Absaugströmung im Gehäuse befindliche Partikel abzusaugen. Dadurch wird verhindert, dass diese Partikel in das Pulverbett fallen und einen Recyclingvorgang des Pulvers erschweren.Due to the separate drive, it is also advantageously possible to supply the grinding device at a first speed to the layer area to be ground or away from it and to move at a second, preferably lower speed over the layer area to be ground. As a result, the time intervals required for the grinding process are shortened. The housing of the grinding device may be provided with a suction device, which is suitable to suck by targeted suction flow in the housing particles. This prevents these particles falling into the powder bed and making the recycling process of the powder difficult.
Vorzugsweise wird das Gehäuse der Schleifvorrichtung quer zu seiner Verfahrrichtung von der Absaugströmung durchströmt. Die Absaugung von Schleifrückständen kann über die Längsausnehmung erfolgen, die über der Baukammer-Seitenwand oder in der Prozesskammer-Seitenwand angeordnet ist. Das riemenförmige Antriebsmittel ist als Zahnriemen ausgebildet, der die ihn führende Längsausnehmung abdeckt. Dadurch entsteht quasi ein ausreichend abgedichteter Strömungskanal, der zur Abführung der Partikel verwendet werden kann.Preferably, the housing of the grinding device is traversed transversely to its direction of the suction flow. The extraction of grinding residues can take place via the longitudinal recess, which is arranged above the building chamber side wall or in the process chamber side wall. The belt-shaped drive means is designed as a toothed belt, which covers the longitudinal recess leading to it. This creates a quasi-sealed flow channel, which can be used to remove the particles.
