Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung dreidimensionaler Objekte gemäß den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a device for producing three-dimensional objects according to the features of the preamble of
Bei derartigen Vorrichtungen wird in einer Baukammer Pulver schichtweise aufgetragen, wobei in der zuletzt aufgetragenen Schicht jeweils vorgegebene Flächen durch Energieeintrag beispielsweise mittels eines Lasers verfestigt werden. Auf diese Art und Weise wird ein dreidimensionales Objekt schichtweise gebaut, wobei sich insbesondere komplizierte Hohlräume innerhalb des gebauten Objektes oder sehr feine Strukturen besonders einfach realisieren lassen.In such devices powder is applied in layers in a building chamber, wherein in the last layer applied respectively predetermined surfaces are solidified by energy input, for example by means of a laser. In this way, a three-dimensional object is built in layers, with particularly complicated cavities within the built object or very fine structures can be particularly easily implemented.
Eine Herausforderung bei den gattungsgemäßen Verfahren besteht darin, dass das Aufbaumaterial zum Sintern oder auch Schmelzen exakt an den vorgegebenen Stellen auf eine vorgegebene Temperatur zu erwärmen ist, um den Sinter- oder Schmelzprozess zu vollführen. Aufgrund der räumlichen Ausdehnung beispielsweise des Laserflecks auf der Oberfläche lässt sich der Energieeintrag nicht beliebig genau kontrollieren, insbesondere erwärmt ein Laserstrahl nicht nur die bedeckte Fläche, vielmehr wird durch Wärmeaustauschprozesse auch das umgebende Material erwärmt.A challenge in the generic method is that the building material for sintering or melting is to heat exactly at the predetermined locations to a predetermined temperature in order to perform the sintering or melting process. Due to the spatial extent, for example, of the laser spot on the surface, the energy input can not be controlled arbitrarily precisely, in particular, a laser beam heats not only the covered surface, but is also heated by heat exchange processes, the surrounding material.
Um Verwerfungen im Objekt aufgrund unterschiedlicher Energieeinträge und somit Verfestigungsstadien des Aufbaumaterials zu vermeiden ist unter anderem bekannt, das Aufbaumaterial zu beheizen. Weist das Aufbaumaterial nämlich eine Temperatur im Bereich nahe unter der Schmelztemperatur auf, so ist der benötigte Energieeintrag geringer, um die Schmelztemperatur zu erreichen. Auf diese Art und Weise fallen auch die Wärmetransportprozesse nicht mehr so stark ins Gewicht, wodurch das dreidimensionale Objekt insgesamt homogener gebaut ist.In order to avoid distortions in the object due to different energy inputs and thus solidification stages of the building material is among other things known to heat the building material. If the build-up material has a temperature in the range close to below the melting temperature, the energy input required is lower in order to reach the melting temperature. In this way, the heat transport processes are no longer so strong, making the three-dimensional object is built more homogeneous overall.
Zum Beheizen des Aufbaumaterials ist es bekannt, Heizelemente oberhalb der Baukammer oder um die Baukammer herum anzubringen. Auch eine Anordnung von Heizelementen unterhalb des Trägers in der Baukammer ist bekannt.For heating the building material, it is known to install heating elements above the building chamber or around the building chamber. An arrangement of heating elements below the carrier in the building chamber is known.
Üblicherweise wird die Anordnung der Heizelemente oberhalb oder am Rand der Baukammer bevorzugt, da bei diesen Ausgestaltungen die direkteste Einwirkmöglichkeit auf die oberste Schicht Aufbaumaterial, die sich immer am oberen Rand der Baukammer befindet, gewährleistet ist.Usually, the arrangement of the heating elements is preferred above or at the edge of the building chamber, as in these embodiments, the most direct impact possibility on the uppermost layer of building material, which is always located at the top of the building chamber, is guaranteed.
Eine Heizvorrichtung unterhalb des Trägers ist andererseits dahingehend vorteilhaft, dass die Baukammer im oberen Bereich vollumfänglich zugänglich bleibt. Die Anordnung einer Heizung unterhalb des Trägers ist allerdings problematisch, da sich die Materialien bei Erwärmung verformen.On the other hand, a heating device below the carrier is advantageous in that the building chamber remains fully accessible in the upper area. The arrangement of a heater below the carrier is problematic, however, because the materials deform when heated.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zum Herstellen dreidimensionaler Objekte mit den Merkmalen des Oberbegriffes des Anspruches 1 derart weiterzubilden, bei der die Verwendung einer Heizvorrichtung verbessert ist. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst, vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The invention is therefore based on the object, a device for producing three-dimensional objects with the features of the preamble of
Als Kern der Erfindung wird es angesehen, dass das Heizelement selbst zum einen nicht fest mit der Tragevorrichtung verbunden ist und zum anderen zusätzlich eine Ausdehnung des erwärmten Heizelementes gewährleistet ist. Aufgrund dieser Ausgestaltung ist es weiterhin möglich, die Heizvorrichtung zwischen Träger und Bauplatte anzuordnen und dabei höhere Temperaturen zu realisieren, als dies vorher möglich war.As the core of the invention, it is considered that the heating element itself is not firmly connected to the carrying device and on the other hand, an extension of the heated heating element is ensured. Due to this configuration, it is also possible to arrange the heater between the support and building board and thereby realize higher temperatures than was previously possible.
Dabei wird unter einer schwimmenden Lagerung verstanden, dass das Heizelement in der Ausnehmung nicht fixiert ist, insbesondere nicht durch die Seitenwände.It is understood by a floating storage that the heating element is not fixed in the recess, in particular not by the side walls.
Um eine Wärmeableitung des Heizelements in Richtung des Trägers bzw. in die Baukammer unterhalb des Trägers zu reduzieren, ist vorgesehen, dass die Heizvorrichtung einen plattenförmigen Träger aus Isoliermaterial umfasst, der eine Ausnehmung besitzt. Die Heizvorrichtung kann also in dem Träger der Baukammer gelagert werden, wobei der Isolationsträger die Wärmeleistung der Heizvorrichtung vor der Umgebung gesehen in Richtung des Trägers der Baukammer abschirmt.In order to reduce a heat dissipation of the heating element in the direction of the carrier or in the building chamber below the carrier, it is provided that the heating device comprises a plate-shaped carrier made of insulating material, which has a recess. The heating device can thus be stored in the support of the building chamber, wherein the insulating support shields the heat output of the heater from the environment seen in the direction of the support of the building chamber.
Um trotz der schwimmenden Lagerung eine gewisse Positionierung des Heizelementes zu gewährleisten, kann vorgesehen sein, dass das Heizelement randseitig durch nachgiebige Isolationsdichtelemente abgestützt ist. Diese Isolationsdichtelemente fixieren das Heizelement so, dass es sich in der Ausnehmung nicht unkontrolliert bewegt, dennoch ist eine Ausdehnung des Heizelements aufgrund der Erwärmung während des Heizvorgangs möglich. Die Isolationsdichtelemente verhindern aufgrund ihrer Isolationswirkung einen Wärmeübertrag vom Heizelement an die Seitenwände der Heizvorrichtung bzw. an den plattenartig ausgebildeten Träger, in dem das Heizelement schwimmend gelagert ist.In order to ensure a certain positioning of the heating element despite the floating bearing, it can be provided that the heating element is supported on the edge side by resilient insulation sealing elements. These insulation sealing elements fix the heating element in such a way that it does not move in an uncontrolled manner in the recess, nevertheless an expansion of the heating element due to the heating during the heating process is possible. Due to their insulating effect, the insulation sealing elements prevent heat transfer from the heating element to the side walls of the heating device or to the plate-like carrier in which the heating element is mounted in a floating manner.
Vorteilhafterweise kann der Boden der Ausnehmung mit einer Rillenstruktur versehen sein, auf welcher das Heizelement aufliegt. Mit dieser Rillenstruktur kann die Wärmeleitung zwischen dem Heizelement und dem Rest der Heizvorrichtung verringert werden.Advantageously, the bottom of the recess may be provided with a groove structure on which the heating element rests. With this groove structure, the heat conduction between the heating element and the rest of the heater can be reduced.
Zur Wärmeerzeugung weist das Heizelement vorteilhafterweise wenigstens zwei Heizstäbe auf, die z. B. einen rechteckigen Querschnitt haben können. Die Heizstäbe sind längliche Stäbe, die sich über den größten Teil der Länge des Heizelementes erstrecken. Zum Energieeintrag sind die Heizstäbe mit ihrem einen Ende an einer Stromquelle angeschlossen. Aufgrund des in den Heizstäben vorhandenen elektrischen Widerstands wird so eine Widerstandsheizung realisiert. Um dieses Ende der Heizstäbe zu der Stromquelle führen zu können, weist die Heizvorrichtung am Boden der Ausnehmung Öffnungen auf, durch die die Heizstäbe geführt werden. Im Bereich durch die Öffnung sind die Heizstäbe geknickt bzw. gebogen. For heat generation, the heating element advantageously has at least two heating elements, the z. B. may have a rectangular cross-section. The heating rods are elongated rods which extend over most of the length of the heating element. For energy input, the heating rods are connected at one end to a power source. Due to the existing in the heating elements electrical resistance so a resistance heating is realized. To be able to lead this end of the heating elements to the power source, the heater at the bottom of the recess openings through which the heating elements are performed. In the area through the opening, the heating elements are bent or bent.
Um eine symmetrische Verteilung der Heizstäbe zu erreichen können die Öffnungen für die Heizstäbe auf den beiden unterschiedlichen Hälften des Bodens der Ausnehmung angeordnet sein. Da die Ausnehmungen einen gewissen Abstand voneinander aufweisen müssen und die Heizstäbe einen kleineren Querschnitt haben als die Ausnehmungen, lässt sich so eine größere Dichte an Heizstäben im zentralen Bereich des Heizelementes realisieren.In order to achieve a symmetrical distribution of the heating elements, the openings for the heating elements can be arranged on the two different halves of the bottom of the recess. Since the recesses must have a certain distance from each other and the heating elements have a smaller cross-section than the recesses, a greater density of heating elements in the central region of the heating element can thus be realized.
Mit besonderem Vorteil können die Heizstäbe vergossen werden. Die dazu verwendete Vergussmasse dient der Homogenisierung der Wärmeabgabe der Heizstäbe.With particular advantage, the heating elements can be cast. The potting compound used for homogenization of the heat output of the heating elements.
Statt des Eingießens in eine Vergussmasse kann auch ein mit Schlitzen bzw. Ausnehmungen versehenes Koppelelement vorgesehen sein, wobei die Heizstäbe in das Koppelelement bzw. dessen Ausnehmungen eingelegt und sogar darin fixiert werden können. Insbesondere kann zwischen den Heizstäben und dem Kopplungselement eine gute Wärmekopplung bestehen. Oberhalb der Ausnehmungen in Richtung zur Bauplatte hin kann das Kopplungselement mehrere Schichten aus unterschiedlichen Materialien aufweisen. Diese Schichten können insbesondere unterschiedliche Wärmeleitfähigkeiten aufweisen, um eine weitere Homogenisierung der Wärmeabgabe zu erzielen.Instead of pouring into a casting compound may also be provided with slots or recesses coupling element, the heating elements can be inserted into the coupling element or its recesses and even fixed therein. In particular, a good thermal coupling can exist between the heating elements and the coupling element. Above the recesses in the direction of the building board towards the coupling element may have multiple layers of different materials. In particular, these layers may have different thermal conductivities in order to achieve a further homogenization of the heat release.
Der plattenartig ausgebildete Träger selbst kann auf einer trogartig ausgebildete Isolationswanne gelagert werden. Durch diese doppelte Isolierung wird die Isolationsfunktion des Gesamtaufbaus verbessert.The plate-like carrier itself can be stored on a trough-shaped insulation pan. This double insulation improves the isolation function of the overall structure.
Mit besonderem Vorteil kann die Bauplatte auf Isolationsdichtelementen aufliegen, die das Heizelement seitlich umgeben.With particular advantage, the building board can rest on insulation sealing elements which laterally surround the heating element.
Vorteilhafterweise kann die Bauplatte mit dem plattenartig ausgebildeten Träger im Eckbereich durch bolzenartige Elemente gehalten sein. Dadurch wird die Bauplatte mit dem plattenartig ausgebildeten Träger insoweit fixiert, als Verschiebungen des plattenartig ausgebildeten Trägers und der Bauplatte gegeneinander verhindert werden. Das Heizelement zwischen dem plattenartig ausgebildeten Träger und der Bauplatte kann sich allerdings ausdehnen und somit bewegen, da es schwimmend gelagert ist. Aufgrund dieses Aufbaus kommt es zu keinerlei mechanischer Krafteinwirkung zwischen dem Heizelement und der Bauplatte und auch nicht zwischen dem Träger und dem Heizelement.Advantageously, the building board with the plate-like support can be held in the corner by bolt-like elements. As a result, the building board is fixed to the plate-like support insofar as displacements of the plate-like support and the building board are prevented from each other. However, the heating element between the plate-like carrier and the building board can expand and thus move, since it is floating. Due to this structure, there is no mechanical force between the heating element and the building board and also not between the carrier and the heating element.
