Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur schichtweisen Herstellung eines dreidimensionalen Objektes.The The invention relates to a device and a method for layers Production of a three-dimensional object.
Eine
derartige Vorrichtung ist unter anderem aus der
Die Qualität eines mit einer derartigen Vorrichtung hergestellten Produktes wird häufig durch Temperaturschwankungen während des Herstellungsprozesses beeinträchtigt. Insbesondere erhöht sich im Laufe des Herstellungsprozesses oft eine Temperatur im Bereich des Produktes durch die zugeführte Strahlungsenergie und/oder ein Teil des teilchenförmigen Baumaterials wird durch ein Herausfahren einer Maskenplatte stark abgekühlt.The Quality of a manufactured with such a device Product is often due to temperature changes during affected by the manufacturing process. Especially In the course of the manufacturing process, a temperature often increases in the area of the product due to the supplied radiant energy and / or becomes a part of the particulate building material greatly cooled by retraction of a mask plate.
Der Erfindung liegt die Aufgabe zu Grunde, eine verbesserte Vorrichtung und ein verbessertes Verfahren zur schichtweisen Herstellung eines dreidimensionalen Objektes anzugeben.Of the Invention is based on the object, an improved device and an improved process for the layered production of a indicate three-dimensional object.
Die Aufgabe wird erfindungsgemäß durch eine Anordnung mit den in Anspruch 1 angegebenen Merkmalen und ein Verfahren mit den in Anspruch 7 angegebenen Merkmalen gelöst.The Object is achieved by an arrangement having the features specified in claim 1 and a method with solved the features specified in claim 7.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur schichtweisen Herstellung eines dreidimensionalen Objektes durch Sintern oder Verschmelzen von Teilchen eines Baumaterials mittels einer elektromagnetischen Strahlung wenigstens einer Strahlungsquelle. Dabei ist jede Objektschicht mittels einer Maskenplatte herstellbar, die mit einem Maskenmuster für die jeweilige Objektschicht versehen und zwischen die wenigstens eine Strahlungsquelle und eine Teilchenschicht einbringbar ist.The The invention relates to a device and a method for layers Production of a three-dimensional object by sintering or Melting of particles of a building material by means of an electromagnetic Radiation of at least one radiation source. Each object layer is by means of a mask plate produced with a mask pattern for provided the respective object layer and between the at least a radiation source and a particle layer can be introduced.
Die erfindungsgemäße Vorrichtung zeichnet sich aus durch eine Heizeinrichtung, mittels derer Luft auf eine vorgebbare Temperatur erwärmbar ist, und eine Prozesskammer mit einer Lufteingangsöffnung, durch die der Prozesskammer von der Heizeinrichtung erwärmte Luft zuführbar ist, und einer Luftausgangsöffnung, durch die Luft aus der Prozesskammer abführbar ist.The inventive device is characterized by a heating device, by means of which air to a predefinable Temperature is heated, and a process chamber with a Air inlet opening through which the process chamber of the Heating device heated air can be supplied, and an air outlet opening, through the air from the process chamber is deductible.
Die Erfindung sieht ferner ein Verfahren zur schichtweisen Herstellung eines dreidimensionalen Objektes in einer Prozesskammer vor, wobei der Prozesskammer auf eine vorgebbare Temperatur erwärmte Luft zugeführt wird.The The invention further provides a process for layered production a three-dimensional object in a process chamber, wherein the process chamber heated to a predetermined temperature Air is supplied.
Die Zuführung erwärmter Luft mit einer vorgebbaren Temperatur in die Prozesskammer ist vorteilhaft, da dadurch die Temperatur in der Prozesskammer stabilisiert werden kann. Dies verbessert die Schichtbildung und damit die mechanischen Eigenschaften und die Qualität der hergestellten Produkte, sowie die Reproduzierbarkeit der Herstellungsergebnisse.The Supply of heated air with a predefinable Temperature in the process chamber is advantageous because thereby the Temperature in the process chamber can be stabilized. This improves the layer formation and thus the mechanical properties and the quality of the manufactured products, as well as the reproducibility the manufacturing results.
