In derartigen Vorrichtungen werden Laser-Sinter-Verfahren, insbesondere selektive Laser-Sinter-Verfahren oder Laserschmelzverfahren durchgeführt, wobei beim typischen Sinterverfahren verfestigbare Aufbaumaterialien nur soweit erhitzt werden, daß es sich zu einem festen Formkörper verbinden. Bei Laserschmelzverfahren werden insbesondere metallische Werkstoffe schichtweise komplett durchgeschmolzen, um aus dem Aufbaumaterial ohne wesentliche Nachbearbeitung z. B. verwendbare Werkzeuge, insbesondere Prototyp-Werkzeuge herzustellen.In Such devices are laser sintering methods, in particular Selective laser sintering or laser melting performed, wherein In the typical sintering process solidifiable construction materials only so far as to be heated become a solid shaped body connect. In laser melting, in particular metallic Materials completely melted layer by layer to get out of the building material without significant post-processing z. B. usable tools, in particular Produce prototype tools.
Derartige Verfahren werden zusammen mit anderen Verfahren unter dem Oberbegriff „Rapid Prototyping" subsumiert.such Procedures are subsumed together with other methods under the generic term "rapid prototyping".
Bekannte Vorrichtungen weisen in der Regel neben dem Bauraum zur Materialzuführung einen gesonderten Vorratsbehälter auf, der mit der Dosiereinrichtung zur Zuführung des Aufbaumaterials zusammenwirkt. Nach dem eigentlichen Bauvorgang wird das fertig gestellte dreidimensionale Objekt nach Abkühlung aus dem Bauraum entnommen, der Bauraum wird dann vollständig entleert und von den Pulverrückständen, gesäubert die beim Bauprozeß nicht verfestigt wurden. Dies ist umständlich, das Handling vom Aufbaumaterial ist auch für die Bedienungsperson aus Gesundheitsaspekten nicht problemlos durchführbar. Automatische Vorrichtungen zum Entleeren des Bauraumes und zum Überführen des Aufbaumaterials in den Dosierbehälter sind kompliziert, wartungsintensiv und teuer.Known Devices generally have a separate space in addition to the space for material supply reservoir on, which cooperates with the metering device for supplying the building material. After the actual construction process, the finished three-dimensional Object after cooling taken from the space, the space is then completely emptied and from the powder residues, that cleaned not at the construction process were solidified. This is awkward the handling of the building material is also for the operator Health aspects are not easily feasible. Automatic devices for Emptying the installation space and transferring the Building material in the dosing are complicated, maintenance-intensive and expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit den Merkmalen des Oberbegriffes des Anspruches 1 derart auszubilden, daß sie problemloser, insbesondere im Hinblick auf das Pulverhandling innerhalb der Maschine zu bedienen ist. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen 2-16.Of the Invention is based on the object, a device with the features of the preamble of claim 1 in such a way that they are easier, especially with regard to powder handling within the machine to use. This task is characterized by the characterizing features of claim 1, advantageous developments of the invention will become apparent from the dependent claims 2-16.
Als Kern der Erfindung wird es angesehen, überschüssiges Aufbaumaterial innerhalb des Behälterbereiches aufzufangen, wozu neben dem Bauraum mindestens ein Überlaufbehälter angeordnet ist, der ebenfalls mit einer höhenverstellbaren Bodenplattformen ausgerüstet ist. Besonders vorteilhaft ist die Anordnung von zwei Überlaufbehältern beidseitig neben dem kombinierten Bau-/Dosierraum. Um Aufbaumaterial von den Überlaufbehältern in den Bau-/Dosierraum zurückzufördern, ist es lediglich erforderlich, die höhenverstellbaren Bodenplattform(en) etwas anzuheben, wenn sich der Beschichterrakel ganz außen an der Behälterseitenkante befindet. Durch Verfahren des Beschichters über den Überlaufbehälter in Richtung des Bauraumes wird Material schichtweise (in weit dickeren Schichten als beim Aufbauprozeß) zurückgeführt. Dadurch bekommt die Beschichtereinrichtung eine Doppelfunktion, sie dient nämlich als Beschichter im eigentlichen Sinne und als Fördereinrichtung zur Förderung des Aufbaumaterials aus den Überlaufbehältern zurück in den Bau-/Dosierraum. Eine derartige Art der Rückführung ist sowohl bei Vorrichtungen von dreidimensionalen Objekten möglich, die einen getrennten Bauraum und einen getrennten Dosierraum haben, als auch bei solchen, bei denen Bauraum und Dosierkammer ohne Zwischenwandung zusammenhängen. Der Beschichter dient gleichzeitig als Rückführelement von Aufbaumaterial in den Dosierbehälter, wobei die Überlaufbehälter gleichzeitig die Funktion von Dosierbehältern übernehmen können, das heißt der Beschichterrakel aus den Überlaufbehältern hoch gedrücktes Material sogleich auf die Bauplattform beschichten kann und überschüssiges Material in die eigentliche Dosierkammer (oder den anderen Überlaufbehälter) zurückführt.As the core of the invention, it is considered to collect excess building material within the container area, including at least one overflow container is arranged in addition to the space, which is also equipped with a height-adjustable floor platforms. Particularly advantageous is the arrangement of two overflow containers on both sides next to the combined construction / dosing. In order to return building material from the overflow tanks to the construction / metering room, it is only necessary to slightly raise the height-adjustable floor platform (s) when the coating squeegee is located entirely outside the container side edge. By moving the coater through the overflow tank in the direction of the construction space, material is returned layer by layer (in much thicker layers than during the build-up process). Thus, the coater gets a double function, namely it serves as a coater in the true sense and as a conveyor for conveying the building material from the overflow containers back into the construction / dosing. Such a kind of return Guidance is both in devices of three-dimensional objects possible, which have a separate space and a separate dosing, as well as those in which space and metering chamber are related without intermediate wall. The coater also serves as a return element of building material in the dosing, wherein the overflow container can simultaneously take over the function of dosing, that is, the coater squeeze out of the overflow containers high-pressure material immediately on the build platform and excess material in the actual dosing (or the other Overflow tank) returns.
Es hat sich bei bestimmten Aufbaumaterialien insbesondere in Verbindung mit Laserschmelzverfahren als zweckdienlich erwiesen, das Verfahren unter Überdruck und insbesondere in einer sauerstoffreduzierten Atmosphäre durchzuführen. In Weiterbildung der Erfindung wird der mit Überdruck beaufschlagte Gasraum auf den Behälter selbst beschränkt, wodurch Gas gespart werden kann und die Vorrichtungen zur Erzeugung des Überdruckes relativ klein dimensioniert werden können. Wenn der Deckel den Behälter seitlich übergreift, besteht die Möglichkeit einer besonders guten Dichtung und Verrastung des Deckels mit dem Behälter. Vorteilhafterweise wird der Deckel mit den Seitenwandungen des Behälters verrastet, wobei die Verrastung im Bereich der Seitenwandungen vorgenommen werden kann.It has particular connection with certain building materials with laser melting proved to be useful, the method under overpressure and in particular in an oxygen-reduced atmosphere. In Further development of the invention is the pressurized gas space with pressure on the container self-limited, whereby gas can be saved and the devices for generating of overpressure can be relatively small dimensions. When the lid overlaps the container laterally, it is possible a particularly good seal and locking the lid with the Container. Advantageously, the lid is latched to the side walls of the container, with the latching made in the area of the side walls can be.
