摘要: The invention relates to a ceramic feedstock comprising the components a), b) and optionally c), wherein component a) is at least one ceramic material, component b) is at least one binder (B) and optional component c) is at least one additive (A). The ceramic feedstock is preferably provided in form of a filament to be employed in three- dimensional (3D) printing techniques, particularly in a FFF printing process. The inventive ceramic feedstock can, therefore, be successfully employed for the 3D printing of support structures and/or separation layers. Further, the invention also relates to three-dimensional objects as such, in particular three-dimensional green bodies, three-dimensional brown bodies or three-dimensional sintered bodies as well as to a process for the preparation thereof.

摘要: In one example in accordance with the present disclosure, a post processing system is described. The post processing system includes a cooling system to cool the polymer object and a heating device to raise the temperature of the polymer object. The post processing system also includes a controller. The controller determines parameters for heating and cooling. The controller also controls operation of the cooling system to pre-cool the polymer object and controls operation of the heating device to raise the temperature of the polymer object such that a surface of the polymer object rises above the melting temperature of the polymer while an interior portion of the polymer object remains below the melting temperature of the polymer.

摘要: In an example method, benzyl alcohol is applied to a surface of a first polyamide-based 3D object, a surface of a second polyamide-based 3D object, or both the surface of the firs polyamide-based 3D object and the surface of the second polyamide-based 3D object. Each of the first and second polyamide-based 3D objects is independently selected from the group consisting of a second polyamide 3D object and a polyamide elastomer 3D object. The first polyamide-based 3D object has a different chemical composition than the second polyamide-based 3D object. After the benzyl alcohol is applied, the surface of the first polyamide-based 3D object is directly contacted with the surface of the second polyamide-based 3D object. While the surfaces are in contact, the first polyamide-based 3D object and the second polyamide-based 3D object are exposed to a predetermined temperature for a predetermined time to weld the surfaces together.

Das Verfahren umfasst ein Bereitstellen einer Behandlungsflüssigkeit (5) in einer Kammer (1) einer Vorrichtung (100) sowie ein Bereitstellen der zu behandelnden Polymerelemente. Ferner umfasst das Verfahren optional einen Erwärmungsschritt zum Erhitzen einer Behandlungsflüssigkeit (5) auf eine Temperatur unter einer oberen Schwellentemperatur, wobei die obere Schwellentemperatur in einem Bereich von 1°C bis 80°C unter der Schmelztemperatur des Polymers liegt, aus dem die Polymerelemente (4) geformt sind. Das Verfahren umfasst ferner einen Behandlungs-, vorzugsweise Glättungsschritt, wobei die Polymerelemente (4) mit der Behandlungsflüssigkeit (5) bei einer Temperatur oberhalb einer unteren Schwellentemperatur und unterhalb der oberen Schwellentemperatur für eine vorbestimmte Zeitdauer in Kontakt stehen oder gelangen. Dies erfolgt unter Bedingungen, bei denen die Behandlungsflüssigkeit (5) in flüssiger Form vorliegt. Ferner umfasst das Verfahren optional einen Kühlschritt zum Kühlen der Polymerelemente. Die vorliegende Erfindung betrifft außerdem eine Vorrichtung (100) zur Behandlung von Polymerelementen (4).

摘要: Network enabled 3D printing and automated processing techniques for oral devices are disclosed herein. An example technique includes receiving, via a network (120), a data file representative of a mouth of a user, and printing, by a 3D printer (112), a 3D oral device based on the data file. The example technique may further include automatically ejecting, from the 3D printer, the 3D oral device, and scanning, by a scanner (114), the 3D oral device to generate a 3D scan file of the 3D oral device. The example technique may further include comparing the 3D scan file with the data file to determine at least one feature represented in the 3D scan file that exceeds a deviation threshold relative to a corresponding respective feature represented in the data file; and finishing, by a finishing module (116), the 3D oral device by smoothing the at least one feature on the 3D oral device.
