Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Formkörpers oder Gegenstandes nach der Methode des selektiven Pulverschmelzens oder einer anderen Prototypen-Herstellungsmethode, bei der man ein pulverförmiges Rohmaterial in aufeinander folgend präparierten Schichten durch Bestrahlen mit wenigstens einem, insbesondere gesteuert ablenkbaren Strahl, vorzugsweise Laserstrahl, entsprechend einem der jeweiligen Schicht zugeordneten Querschnittsmuster des Formkörpers zu zusammenhängenden Bereichen verfestigt bzw. verschmelzt.The invention relates to a method for producing a shaped article or article by the method of selective powder melting or other prototyping method in which a powdered raw material in successively prepared layers by irradiation with at least one, in particular controlled deflectable beam, preferably laser beam, accordingly one of the respective layer associated cross-sectional pattern of the molding solidified or merged into contiguous areas.
Unter den Begriffen Stereolithographie, selektives Pulverschmelzen, selektives Laserschmelzen, selektives Lasersintern u. dgl., sind in jüngerer Zeit leistungsfähige Methoden zur Herstellung von Formkörpern auch komplizierter Geometrien bekannt geworden, wobei diese häufig unter dem Begriff „rapid prototyping“ oder „rapid tooling“ oder „rapid manufacturing“ zusammengefassten Methoden im Wesentlichen auf folgendem Prinzip basieren: Der Formkörper, also irgendein herzustellender Gegenstand, wird nach Maßgabe von CAD-Daten bzw. von davon abgeleiteten geometrischen Beschreibungsdaten schichtweise aus einem zunächst flüssigen Rohmaterial oder feinkörnigen bzw. pulvrigen Rohmaterial aufgebaut, indem das Rohmaterial entsprechend einem der jeweiligen Schicht zugeordneten Querschnittsmuster des Formkörpers durch selektives Bestrahlen verfestigt bzw. verschmolzen wird. Üblicherweise erfolgt das Bestrahlen mittels wenigstens einem gesteuert ablenkbaren Laserstrahl. Dabei erfolgt die Steuerung einer den Strahl ablenkenden Strahlablenkeinrichtung mittels einer Steuereinrichtung auf der Basis geometrischer Beschreibungsdaten des herzustellenden Formkörpers, welche üblicherweise von einem Mikrocomputer nach Maßgabe eines entsprechenden Programms aus CAD-Daten abgeleitet und bereitgestellt werden. Der Laserstrahl zeichnet auf der zuletzt präparierten Rohmaterialschicht das dieser Schicht zugeordnete Querschnittsmuster des Formkörpers, um das Rohmaterial dem Querschnittsmuster entsprechend selektiv zu verfestigen bzw. zu verschmelzen. Nach einem solchen Bestrahlungsschritt erfolgt dann die Präparation der nächsten Rohmaterialschicht auf der zuletzt durch Bestrahlen selektiv und bereichsweise verfestigten bzw. verschmolzenen Schicht. Nach Ausbildung einer an ihrer Oberfläche hinreichend glatten Rohmaterialschicht erfolgt dann wieder ein Belichtungsschritt in der vorstehend erläuterten Weise. Der Formkörper entsteht somit Schicht für Schicht, wobei die aufeinander folgend hergestellten Querschnitts-Schichten des Formkörpers aneinander haften.Under the terms stereolithography, selective powder melting, selective laser melting, selective laser sintering, and the like. Like., More recently, powerful methods for the production of moldings, including complicated geometries have become known, these methods are often based on the following principle summarized under the term "rapid prototyping" or "rapid tooling" or "rapid manufacturing": The molding , that is, any object to be manufactured, is built up layer by layer from a first liquid raw material or fine powdery raw material according to CAD data or geometric description data derived therefrom by solidifying the raw material by selective irradiation according to a cross sectional pattern of the molded article associated with the respective layer or merged. Usually, the irradiation takes place by means of at least one controlled deflectable laser beam. The control of a beam deflecting the beam deflection device by means of a control device based on geometric description data of the molded body to be produced, which are usually derived from a microcomputer in accordance with a corresponding program from CAD data and provided. The laser beam records on the last prepared raw material layer the cross-sectional pattern of the shaped body assigned to this layer in order to selectively solidify or fuse the raw material according to the cross-sectional pattern. After such an irradiation step, the preparation of the next raw material layer then takes place on the layer which has been finally or selectively solidified or blended by irradiation. After the formation of a raw material layer which is sufficiently smooth on its surface, an exposure step is then carried out again in the manner explained above. The shaped body thus arises layer by layer, wherein the successively produced cross-sectional layers of the shaped body adhere to one another.
Beim selektiven Verschmelzen von Metallpulvern, wie es beispielsweise in der
In entsprechender Weise erfolgt der Aufbau eines Formkörpers bei Methoden nach dem Prinzip des selektiven Lasersinterns (selective laser sintering), wobei insbesondere Metallpulver mit niedrigschmelzenden Bindemitteln eingesetzt werden.In a corresponding manner, the structure of a shaped body is carried out in methods according to the principle of selective laser sintering (selective laser sintering), in particular metal powder are used with low melting point binders.
Aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, für ein Verfahren der eingangs genannten Art eine vereinfachte Vorgehensweise zur Vermeidung des ungleichmäßigen lokalen Aufheizens bei der Bestrahlung jeweiliger Rohmaterialschichten vorzuschlagen.The present invention has for its object to propose a simplified procedure for avoiding the uneven local heating in the irradiation of respective raw material layers for a method of the type mentioned.
Diese Aufgabe wird gemäß Patentanspruch 1 erfindungsgemäß gelöst durch ein Verfahren zur Herstellung eines Formkörpers nach einer Methode der schnellen Prototypen-Herstellung, insbesondere selektiven Laserschmelzmethode, bei der man ein pulverförmiges Rohmaterial in aufeinander folgend präparierten Schichten durch Bestrahlen mit wenigstens einem, mittels einer steuerbaren Strahlablenkeinrichtung gesteuert ablenkbaren Strahl, vorzugsweise Laserstrahl, entsprechend einem der jeweiligen Schicht zugeordneten Querschnittsmusters des Formkörpers zu zusammenhängenden Bereichen verfestigt bzw. verschmelzt, wobei die Steuerung der Strahlablenkeinrichtung auf der Basis von Geometriebeschreibungsdaten des herzustellenden Formkörpers erfolgt, wobei man die pro Zeiteinheit und Flächeneinheit am jeweiligen Auftreffort des Strahls auf der Schicht auftreffende Strahlungsenergie des Strahls bzw. die durch Bestrahlung zugeführte Energie an der jeweils aktuell bestrahlten Stelle der betreffenden Schicht durch Änderung vorbestimmter Bestrahlungsparameter in Abhängigkeit davon variiert, ob der jeweils aktuell bestrahlte Bereich der Schicht auf einem zusammenhängend verfestigten Bereich oder auf nichtverfestigtem Rohmaterial der vorausgehend bestrahlten Schicht liegt, wobei die vorbestimmten Bestrahlungsparameter Abhängigkeit von und in Zuordnung zu den jeweiligen Geometriebeschreibungsdaten für die zu bestrahlenden Stellen vor der Bestrahlung der jeweiligen Stellen im Voraus festgelegt werden.This object is achieved according to claim 1 according to the invention by a method for producing a shaped article by a method of rapid prototyping, in particular selective laser melting method, in which one controlled a powdered raw material in successively prepared layers by irradiation with at least one, by means of a controllable beam deflecting device deflectable beam, preferably Laser beam, solidified or merged according to a respective layer associated cross-sectional pattern of the shaped body to contiguous areas, wherein the control of the beam deflector based on Geometriebeschreibungsdaten of the shaped body to be produced, wherein the per unit time and unit area incident on the respective location of the beam on the layer Radiation energy of the beam or the energy supplied by irradiation at the respectively irradiated point of the respective layer varies by changing predetermined irradiation parameters depending on whether the currently irradiated area of the layer is on a coherently solidified area or unconsolidated raw material of the previously irradiated layer wherein the predetermined irradiation parameters depend on and in association with the respective geometry description data for the sites to be irradiated before de Irradiation of the respective bodies can be determined in advance.
Es geht somit erfindungsgemäß darum, den durch Bestrahlung bewirkten Energieeintrag in den umzuschmelzenden Bereichen abhängig von den Wärmeleitungsbedingungen in der jeweiligen Umgebung des Strahlauftreffpunkts auf der betreffenden Schicht so zu variieren, dass das pulvrige Rohmaterial an sämtlichen Stellen des zu verfestigenden Querschnittsmusters bei einer Temperatur aus einem relativ kleinen Temperaturbereich verschmolzen wird. Es soll verhindert werden, dass aufgrund lokal unterschiedlicher thermischer Bedingungen (Umschmelztemperaturen) Materialspannungen bzw. Materialverzug oder sonstige nicht erwünschte Verformungen des Formkörpers entstehen.It is therefore according to the invention to vary the irradiation caused by the energy input in the areas to be reflowed depending on the heat conduction conditions in the respective environment of Strahlauftreffpunkts on the relevant layer so that the powdery raw material at all points of the cross-sectional pattern to be solidified at a temperature of a relative small temperature range is merged. It is to be prevented that, due to locally different thermal conditions (remelting temperatures), material stresses or material distortion or other undesirable deformations of the shaped body arise.
Da die Geometrie des herzustellenden Formkörpers durch die CAD-Daten bzw. durch die daraus abgeleiteten Geometriebeschreibungsdaten für die Prozesssteuerung determiniert ist und auch die den Energieeintrag in das Rohmaterial bestimmenden Parameter, wie Absorptionsvermögen des Rohmaterials für das Licht des Laserstrahls, Wärmeleiteigenschaften des Rohmaterials, Wärmeleiteigenschaften des verfestigten Materials, (ggf. geregelte) Basistemperatur des Materials, Laserstrahlintensität etc. bestimmbar sind, kann gemäß der vorliegenden Erfindung prinzipiell für jeden zu verfestigenden Punkt des Formkörpers eine im Voraus getroffene Festlegung der Bestrahlungsbedingungen erfolgen. Gemäß einer Variante dieses Aspekts der Erfindung werden somit prozessvorbereitend Datensätze mit Daten der betreffenden Bestrahlungsparameter, wie Strahlungsleistung, Bestrahlungsdauer etc. in Zuordnung zu den CAD-Daten bzw. Geometriebeschreibungsdaten des Formkörpers erzeugt. Die Datenvorbereitung wird somit so getroffen, dass nicht nur die Geometriebeschreibungsdaten als Grundlage für die Steuerung des Herstellungsprozesses im Vorfeld ermittelt werden, sondern auch die „Energieeintragparameter“ oder Bestrahlungsparameter in Abhängigkeit von und in Zuordnung zu den Geometriebeschreibungsdaten.Since the geometry of the shaped article to be produced is determined by the CAD data and the process control data derived therefrom, and also the parameters determining the energy input into the raw material, such as the absorption power of the raw material for the light of the laser beam, heat conduction properties of the raw material, heat conduction properties of the raw material solidified material, (optionally regulated) base temperature of the material, laser beam intensity, etc. can be determined according to the present invention can be made in principle for each point to be solidified point of the molding in advance made fixing the irradiation conditions. In accordance with a variant of this aspect of the invention, data sets with data of the relevant irradiation parameters, such as radiation power, irradiation duration, etc., are thus generated in preparation in association with the CAD data or geometry description data of the molded body. The data preparation is thus made so that not only the geometry description data are determined as a basis for the control of the manufacturing process in advance, but also the "energy input parameters" or irradiation parameters depending on and in association with the Geometriebeschreibungsdaten.
Auf diese Weise kann man die unterschiedliche Wärmetransportfähigkeit von pulvrigem Rohmaterial einerseits und bereits zusammenhängend verschmolzenem Rohmaterial andererseits berücksichtigen, um zu gewährleisten, dass der Strahl an sämtlichen belichteten Stellen eines Querschnittsmusters das Material mit im Wesentlichen der gleichen Temperatur verschmilzt. An Stellen, an denen die aktuell bestrahlte Schicht auf einem zusammenhängend verfestigten Bereich liegt, wird die pro Zeiteinheit und Flächeneinheit am Auftreffort des Strahls auf der Schicht auftreffende Strahlungsenergie größer gewählt, als in Schichtbereichen, in denen die Schicht auf nichtverfestigtem Rohmaterial der vorausgehenden Schicht liegt. Allgemein kann bei der Bestrahlung berücksichtigt werden, ob in beliebigen Richtungen gut wärmeleitende Pfade durch bereits verfestigtes Material des Formkörpers in der Umgebung des Strahlauftreffpunktes existieren.In this way, one can take into account the differential heat transfer capability of powdery raw material on the one hand and already fused raw material on the other to ensure that the beam fuses the material at substantially the same temperature at all exposed locations of a cross-sectional pattern. At locations where the currently irradiated layer is on a contiguously solidified area, the radiation energy incident on the layer per unit time and unit area at the point of impact of the beam is made larger than in layer areas where the layer is on unconsolidated raw material of the preceding layer. In general, it can be taken into account in the irradiation whether paths of good heat conduction exist in any direction through already solidified material of the shaped body in the vicinity of the beam impingement point.
Dem Gesichtspunkt der Berechnung oder Festlegung von Bestrahlungsparametern in Abhängigkeit von Wärmeleitungsbedingungen in der jeweiligen Umgebung der zu bestrahlenden Stellen und die geometrische Zuordnung dieser Bestrahlungsparameter zu den die zu bestrahlenden Stellen geometrisch determinierenden Geometriebeschreibungsdaten des herzustellenden Formkörpers kommt im Rahmen der vorliegenden Erfindung selbständige und besondere Bedeutung zu.The aspect of the calculation or definition of irradiation parameters as a function of heat conduction conditions in the respective surroundings of the sites to be irradiated and the geometrical assignment of these irradiation parameters to the geometrically determining geometric description data of the shaped body to be irradiated are independent and of particular importance in the context of the present invention.
Insgesamt ermöglicht die Erfindung ein Verschmelzen des Rohmaterials mit vergleichsweise einheitlicher Schmelzzonentemperatur unabhängig vom jeweiligen Schmelzzonenort, also auch unabhängig davon, ob der jeweils aktuell bestrahlte Bereich der Schicht auf einem zusammenhängend verfestigten Bereich oder auf nicht verfestigtem Rohmaterial der vorausgehenden Schicht liegt.Overall, the invention makes it possible to fuse the raw material with a comparatively uniform melt zone temperature irrespective of the particular melting zone location, ie also irrespective of whether the region of the layer currently irradiated lies on a coherently solidified region or on unconsolidated raw material of the preceding layer.
