Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung von dreidimensionalen Objekten durch aufeinanderfolgendes Verfestigen von Schichten eines pulverförmigen, mittels elektromagnetischer Strahlung, insbesondere gebündelter Strahlung wie Laserstrahlung oder Elektronenstrahlung verfestigbaren Aufbaumaterials, mit den weiteren Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a device for the production of three-dimensional objects by successive solidification of layers of a pulverulent build-up material which can be solidified by means of electromagnetic radiation, in particular bundled radiation such as laser radiation or electron radiation, with the further features of the preamble of claim 1.
Derartige Vorrichtungen werden in der Regel als Lasersinter-(SLS) oder Laserschmelz-(SLM)Maschinen bezeichnet und weisen in der Regel eine Tragevorrichtung zum Tragen des herzustellenden Objektes auf. Eine Beschichtungsvorrichtung dient dazu, pulverartiges Baumaterial auf die Tragevorrichtung oder eine zuvor gebildete und zumindest teilweise verfestigte Schicht aufzubringen. Eine Bestrahlungsvorrichtung dient dazu, die Schichten des Aufbaumaterials an den dem jeweiligen Querschnitt des Objektes entsprechenden Stellen zu verfestigen. Die Tragevorrichtung ist innerhalb der Baukammer höhenverlagerbar angeordnet. Die Strahlung wird über eine Scannervorrichtung geführt, die geeignet ist, den Laserstrahl abhängig von Baudaten auf zu verfestigende Stellen der Pulverschicht zu lenken und dort den Sintervorgang oder einen Schmelzvorgang durchzuführen, der zu einer Verfestigung der Schicht und einer Verbindung mit darunterliegenden Schichten des Baumaterials führt.Such devices are typically referred to as laser sintering (SLS) or laser melting (SLM) machines and typically include a carrying device for supporting the object to be manufactured. A coating device serves to apply powder-like building material to the carrying device or to a previously formed and at least partially solidified layer. An irradiation device serves to solidify the layers of the building material at the locations corresponding to the respective cross-section of the object. The carrying device is arranged höhenverlagerbar within the building chamber. The radiation is passed through a scanner device, which is suitable for directing the laser beam depending on construction data to be solidified points of the powder layer and there perform the sintering process or a melting process, which leads to a solidification of the layer and a connection with underlying layers of the building material.
Bei Herkömmlichen SLM- oder SLS-Vorrichtungen wird nach Abschluss eines Bauvorganges die Tragevorrichtung in der Regel in eine obere Stellung verbracht und das nicht verfestigte Pulver aus der Baukammer entfernt, so dass das hergestellte Objekt freiliegt und nach oben oder nach vorne aus der Baukammer entnommen werden kann. Es ist ferner bereits bekannt, die erste oder die ersten Schichten des Baumaterials auf einer Bauplatte zu verfestigen, die vor Beginn des Bauprozesses auf der Tragevorrichtung angebracht werden kann und nach Abschluss des Bauprozesses zusammen mit dem Objekt aus der Gesamtvorrichtung entnommen wird.In conventional SLM or SLS devices, after completion of a construction process, the carrying device is usually placed in an upper position and the non-solidified powder is removed from the building chamber, so that the manufactured object is exposed and removed upward or forward from the building chamber can. It is also already known to consolidate the first or the first layers of the building material on a building board, which can be mounted on the support device prior to the start of the building process and is removed from the overall device together with the object after completion of the building process.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der vorgenannten Art mit den Merkmalen des Oberbegriffes des Anspruches 1 derart weiterzubilden, dass mit ihr ein kontinuierlicher Bauvorgang durchgeführt werden kann, d. h. eine Vielzahl von Teilen gleicher oder unterschiedlicher Art nacheinander hergestellt werden können, ohne den eigentlichen Bauvorgang zu unterbrechen, wobei hergestellte Objekte aus der Baukammer entnehmbar sein sollen, während der Bauvorgang an anderen Objekten noch läuft. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The invention has the object of providing a device of the aforementioned type with the features of the preamble of claim 1 such that with her a continuous construction process can be performed, d. H. a plurality of parts of the same or different types can be produced one after the other without interrupting the actual construction process, wherein manufactured objects should be removable from the building chamber, while the construction process on other objects is still running. This object is solved by the characterizing features of claim 1. Advantageous developments of the invention will become apparent from the dependent claims.
Anspruch 16 definiert ein kontinuierliches Herstellungs- und Entnahmeverfahren.Claim 16 defines a continuous production and removal process.
Als Kern der Erfindung gemäß Anspruch 1 wird es angesehen, die Baukammer auf ihrer Unterseite durch eine Entnahmeöffnung wenigstens teilweise offen auszugestalten. Die Tragevorrichtung ist derart ausgebildet, dass sie durch die Entnahmeöffnung nach unten zusammen mit dem oder den darauf aufgebauten Objekten insbesondere synchron mit dem Bauprozess herausfahrbar angeordnet ist. Die Objekte sind entweder in einem generativ aufgebauten Gehäuse angeordnet, das im Wesentlichen stangenartig ausgebildet ist oder die Objekte bilden selbst einen im Wesentlichen stangenartigen Formkörper. Entweder das Gehäuse mit den darin angeordneten eigentlichen Objekten oder der stangenartige Formkörper selbst wird nach unten kontinuierlich zusammen mit der Tragevorrichtung aus der Bauvorrichtung herausgefahren, er wächst gleichsam im Zuge des Bauvorgangs nach unten heraus und kann sodann entnommen werden, wobei die Höhenverstellung der Bauebene bezogen auf die Beschichterebene von einer Führung im Bereich der Entnahmeöffnung übernommen wird. Die eigentliche Tragevorrichtung verlässt als erstes die Bauvorrichtung nach unten und wird zunächst entweder durch die generativ aufgebauten Gehäuse, die übereinander angeordnete Zellen zur Aufnahme der Objekte umfassen oder den stangenartigen Formkörper gehalten. Mehrere gesonderte Objekte, insbesondere kleine Objekte wie z. B. Schmuckteile, Formteile für Spritzgussformen, dentale Hilfsteile und Kronen und dgl. können in einzelnen Kammern des Gehäuses angeordnet sein, die durch deckelartige Trennwände voneinander getrennt sind. Die deckelartigen Trennwände werden durch seitliche rohrartige Gehäuseabschnitte aneinander gehalten, wobei die Gehäuseabschnitte nicht notwendigerweise geschlossen sein müssen, die Wandungen müssen nur geeignet sein, eine gewisse Führung in der Entnahmeöffnung zu gewährleisten. Vorteilhafterweise entsprechen die gehäusebildenden Wandungsabschnitte des Gehäuses oder des stangenartigen Formkörpers mit ihrer Außenkontur der Außenkontur der Tragevorrichtung, die wiederum an die Innenkontur der Entnahmeöffnung angepasst ist. Tragevorrichtung und die darauf aufgebauten Objektteile oder Gehäuseteile bilden damit eine kontinuierlich und synchron mit der schichtweisen Herstellung des/der Bauteils(e) nach unten aus der Vorrichtung herausfahrende Säule, die motorisch zur Durchführung des Bauprozesses innerhalb der Entnahmeöffnung oder durch sonstige Führungs- oder motorischen Antriebselemente geführt ist.As the core of the invention according to claim 1, it is considered to design the building chamber on its underside by a removal opening at least partially open. The carrying device is designed in such a way that it can be moved outwards through the removal opening, together with the object (s) constructed thereon, in particular synchronously with the building process. The objects are arranged either in a generatively constructed housing which is substantially rod-like or the objects themselves form a substantially rod-like shaped body. Either the housing with the actual objects arranged therein or the bar-like shaped body itself is moved down continuously together with the carrying device from the building device, he grows as it were in the course of construction down and can then be removed, the height adjustment of the building level based on the coater level is taken over by a guide in the region of the removal opening. The actual carrying device first leaves the building device downward and is initially held either by the generatively constructed housing, the cells arranged one above the other for receiving the objects or the rod-like molded body. Several separate objects, especially small objects such. As jewelry parts, moldings for injection molds, dental accessories and crowns and the like. Can be arranged in individual chambers of the housing, which are separated by cover-like partitions. The cover-like partitions are held together by lateral tubular housing sections, wherein the housing sections do not necessarily have to be closed, the walls must only be suitable to ensure a certain leadership in the removal opening. Advantageously, the housing-forming wall sections of the housing or of the rod-like molding correspond with their outer contour to the outer contour of the support device, which in turn is adapted to the inner contour of the removal opening. Carrying device and the object parts or housing parts constructed thereon thus form a continuous and synchronous with the layered production of / the component (s) down out of the device column, the motor to carry out the construction process within the removal opening or other leadership or motor drive elements is guided.
Vorteilhafter Weise sind die Wandungsabschnitte oder Formkörperabschnitte mit Sollbruchstellen oder Trennstellen versehen, so dass nach unten aus der Baukammer herausstehende Objektabschnitte oder Gehäuseabschnitte einfach abgebrochen werden können. Um dies zu erleichtern, können Klemmelemente im Bereich der Entnahmeöffnung vorgesehen sein. Die Entnahmeöffnung hat vorteilhafterweise einen zylindrischen oder sonstigen Querschnitt, der eine exakte Führung des aus der Baukammer herauswachsenden Bauteilestrangs ermöglicht.Advantageously, the wall sections or shaped body sections are provided with predetermined breaking points or separation points, so that downwardly projecting from the building chamber object sections or housing sections can be canceled. To facilitate this, clamping elements may be provided in the region of the removal opening. The removal opening advantageously has a cylindrical or other cross-section which allows an exact guidance of the component strand growing out of the construction chamber.
Das motorisch antreibbare Element, das sowohl für das schichtbildungskonforme Absenken der Bauplattform als auch für den Vorschub nach unten sorgt, kann beispielsweise als eine oder mehrere Antriebsrollen ausgebildet sein, die die Seitenwandungen des Bauteilestrangs beaufschlagen. Die Führungselemente sind dabei vorteilhafterweise pulverdicht ausgebildet, damit Baumaterial nicht nach unten aus der Baukammer herausfallen kann.The motor-driven element, which ensures both the layer formation compliant lowering of the construction platform as well as for the downward feed, may for example be formed as one or more drive rollers, which act on the side walls of the component strand. The guide elements are advantageously formed powder-tight, so that building material can not fall down from the building chamber.
