Abstract
Es ist eine Vorrichtung zum Herstellen eines dreidimensionalen Objektes durch aufeinanderfolgendes schichtweises Verfestigen eines verfestigbaren Materials an dem Querschnitt des Objektes entsprechenden Stellen bereitgestellt. Die Vorrichtung weist einen Bauraum (3) auf, in dem ein Wechselbehälter (10) mit einer Plattform (7) vorgesehen sehen ist, in dem das Objekt herstellbar ist, und die Plattform (7) ist mittels einer Trägervorrichtung (11) an einen Vertikalantrieb (12) befestigt, wobei der Bauraum (3) und der Vertikalantrieb (12) durch eine Wand (13) voneinander getrennt sind.There is provided an apparatus for producing a three-dimensional object by sequentially layering solidifying a solidifiable material at locations corresponding to the cross-section of the object. The device has a construction space (3) in which a swap body (10) with a platform (7) is provided, in which the object can be produced, and the platform (7) by means of a support device (11) to a vertical drive (12) fixed, wherein the space (3) and the vertical drive (12) by a wall (13) are separated from each other.
Description
Die Erfindung betrifft eine Vorrichtung zum Herstellen eines dreidimensionalen Objektes durch Verfestigen eines Baumaterials mittels Energieeintrag.The invention relates to a device for producing a three-dimensional object by solidifying a building material by means of energy input.
Bekannte Maschinen zum additiven Herstellen von dreidimensionalen Objekten durch schichtweises Verfestigen eines verfestigbaren Materials weisen einen Bauraum auf, in dem das herzustellende Objekt auf einer Plattform hergestellt wird. Das zu verfestigende Material wird als Schicht auf der Plattform aufgetragen und mittels Energieeintragung an dem Querschnitt des Objekts entsprechenden Stellen verfestigt. Daraufhin wird die Plattform um eine Schichtdicke abgesenkt und die nächste Schicht aufgetragen und verfestigt und dieser Vorgang wird so lange wiederholt, bis das Objekt vollständig hergestellt ist.Known machines for the additive production of three-dimensional objects by stratified solidification of a solidifiable material have a space in which the object to be produced is produced on a platform. The material to be consolidated is applied as a layer on the platform and solidified by means of energy input at the cross section of the object corresponding points. Then the platform is lowered by one layer thickness and the next layer is applied and solidified and this process is repeated until the object is completely finished.

Bauteile des Vertikalantriebs, die erhöhten Temperaturen ausgesetzt werden, altern schneller. Temperaturunterschiede im Bauraum können zu einem Verzug des Vertikalantriebs führen. Des Weiteren können vermehrt Verschmutzungen durch Kondensate auftreten. Die während des Bauvorganges zunehmende Erwärmung kann außerdem mechanische Schwankungen verursachen.Such a device is known from
Vertical drive components exposed to elevated temperatures age faster. Temperature differences in the installation space can lead to a delay of the vertical drive. Furthermore, increased contamination by condensates can occur. The increasing heating during the construction process can also cause mechanical fluctuations.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zur Herstellung eines dreidimensionalen Objekts bereitzustellen, bei der die Wärmebelastung des Vertikalantriebs verringert werden kann. Die Aufgabe wird gelöst durch eine Vorrichtung nach Patentanspruch 1.The object of the present invention is to provide an apparatus for producing a three-dimensional object in which the heat load of the vertical drive can be reduced. The object is achieved by a device according to claim 1.
Da eine starke Erwärmung des Vertikalantriebs bei einer Vorrichtung gemäß der vorliegenden Erfindung vermieden wird, sind die Materialanforderungen an den Vertikalantrieb nicht so hoch wie in einer vergleichbaren Vorrichtung nach dem Stand der Technik.Since severe heating of the vertical drive is avoided in a device according to the present invention, the material requirements for the vertical drive are not as high as in a comparable device according to the prior art.
Erfindungsgemäß ist der Raum, in dem sich der Vertikalantrieb befindet, vom Bauraum abgegrenzt. Mit der erfindungsgemäßen thermischen Entkoppelung wird ein lokales Abkühlen des Wechselbehälters vermieden, das dort auftreten würde wo der Vertikalantrieb an der Trägervorrichtung angebracht ist.According to the invention, the space in which the vertical drive is located is delimited from the installation space. With the thermal decoupling according to the invention a local cooling of the swap body is avoided, which would occur where the vertical drive is mounted on the support device.
Ein weiterer Vorteil der Erfindung besteht darin, dass der Vertikalantrieb als Ganzes aus der Laser-Sintermaschine heraus entnommen werden kann, wodurch der Aufbau der Maschine modularer und somit das Ersetzen und Reinigen erleichtert werden.A further advantage of the invention is that the vertical drive can be removed as a whole from the laser sintering machine, whereby the construction of the machine modular and thus the replacement and cleaning are facilitated.
