Ein 3D-Druck ist bekannterweise ein Fertigungsverfahren, wobei Material schichtweise aufgetragen und beispielsweise durch bereichsweises Schmelzen der Schicht dreidimensionale Körper hergestellt werden.As is known, 3D printing is a manufacturing process in which material is applied in layers and three-dimensional bodies are produced, for example, by melting the layer in certain areas.

Bei diesen Lösungen wird Pulver schichtweise aufgetragen und wenigstens bereichsweise geschmolzen. Die einzelnen Schichten bilden den Körper aus.With these solutions, powder is applied in layers and melted at least in certain areas. The individual layers form the body.
Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, Metallkörper mittels 3D-Druck insbesondere mit großen Bauraten einfach herzustellen.The invention specified in claim 1 is based on the task of simply producing metal bodies by means of 3D printing, in particular with large construction rates.
Diese Aufgabe wird mit den im Patentanspruch 1 aufgeführten Merkmalen gelöst.This object is achieved with the features listed in claim 1.
Die Verwendungen von wenigstens einer Einrichtung zur konzentrierten Energiezufuhr und Metallpartikeln zur Herstellung wenigstens eines Metallkörpers mittels 3D-Druck zeichnen sich insbesondere dadurch aus, dass Metallkörper insbesondere mit großen Bauraten einfach herstellbar sind.The use of at least one device for the concentrated supply of energy and metal particles for the production of at least one metal body by means of 3D printing is characterized in particular by the fact that metal bodies can be produced easily, in particular with large construction rates.
Zur Herstellung des Metallkörpers werden dazu nacheinander schichtweise aufgebrachte Metallpartikel in Form von Grobkörnern und die Einrichtung zur konzentrierten Energiezufuhr zum Schmelzen und somit zur Herstellung des Metallkörpers verwendet, wobei jeweils die aufgebrachte Schicht der Metallpartikel mit der über die jeweilige Schicht geführten konzentrierten Energie beaufschlagt und geschmolzen wird.To produce the metal body, metal particles in the form of coarse grains applied one after the other in layers and the device for concentrated energy supply are used for melting and thus for producing the metal body, with the applied layer of metal particles being subjected to the concentrated energy conducted over the respective layer and being melted .
Ein Hochleistungs-3D-Druck auf Pulverbasis mit hohen Bauraten benötigt zur Umsetzung von großen Laserleistungen als konzentrierte Energie große Mengen an dem Ausgangsmaterial, welches einen großen ökonomischen Wert besitzt. Gleichzeitig treten bei der Herstellung der Metallkörper Pulververluste auf, da das im Pulverbett zurückbleibende Pulver Schmelzperlen aufweist und somit nicht vollständig wiederverwendet werden kann. Ein Recycling des Pulvers ist aufwändig. Weiterhin muss die Intensität großer Laserleistungen reduziert werden, da das Metallpulver sonst zumindest partiell verdampft.A high-performance powder-based 3D print with high build rates requires large amounts of the starting material for the conversion of large laser powers as concentrated energy, which has a great economic value. At the same time, powder losses occur during the production of the metal body, since the powder remaining in the powder bed has melt beads and can therefore not be completely reused. Recycling the powder is expensive. Furthermore, the intensity of large laser powers must be reduced, otherwise the metal powder will at least partially evaporate.
Vorteilhafterweise sind durch die Verwendung von Metallpartikeln in Form von Grobkörnern, die auch als Granulat bekannt sind, sowohl große Leistungen zur Herstellung der Metallkörper einsetzbar als auch große Metallkörper herstellbar. Metallpartikel in Form von Grobkörnern sind ökonomisch wesentlich günstiger als Metallpulver bereitstellbar. Eine Gefahr einer Verdampfung von Grobkörnern besteht nicht. Die Metallpartikel lassen sich weitestgehend vollständig im Bauprozess verwenden.Advantageously, through the use of metal particles in the form of coarse grains, which are also known as granules, both high outputs can be used to produce the metal bodies and large metal bodies can be produced. Metal particles in the form of coarse grains are economically much cheaper to provide than metal powder. There is no risk of coarse grains evaporating. The metal particles can be used almost completely in the construction process.
Ein weiterer Vorteil besteht darin, dass sich Metallpartikel in Form von Grobkörnern gegenüber Metallpulver einfacher schichtweise auftragen lassen. So können die Grobkörner auch als Schüttgut aufgetragen und danach leicht eingeebnet werden. Gesundheitliche Gefahren durch Feinstaub werden vermieden.Another advantage is that metal particles in the form of coarse grains can be applied in layers more easily than metal powder. The coarse grains can also be applied as bulk material and then slightly leveled. Health hazards from fine dust are avoided.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 bis 10 angegeben.Advantageous developments of the invention are specified in patent claims 2 to 10.
Zur Herstellung des Metallkörpers kann vorteilhafterweise ein nacheinander schichtweise aufgebrachtes und mit der konzentrierten Energie beaufschlagtes Schüttgut von Metallpartikeln in Form von Grobkörnern verwendet werden.To produce the metal body, a bulk material of metal particles in the form of coarse grains, applied in layers one after the other and subjected to the concentrated energy, can advantageously be used.
Zur Herstellung des Metallkörpers kann optional ein nacheinander schichtweise aufgebrachtes und mit der konzentrierten Energie beaufschlagtes Schüttgut von vorgepressten Metallpartikeln in Form von Grobkörnern verwendet werden. To produce the metal body, a bulk material of pre-pressed metal particles in the form of coarse grains, applied one after the other in layers and subjected to the concentrated energy, can optionally be used.
Vorteilhafterweise können zur Herstellung des Metallkörpers Metallpartikel mit einer Korngröße größer/gleich 100 µm und gleich/kleiner 4000 µm verwendet werden.Advantageously, metal particles with a grain size greater than/equal to 100 μm and equal to/less than 4000 μm can be used to produce the metal body.
Optional können zur Herstellung des Metallkörpers Metallpartikel in Form von Grobkörnern aus recycelten Metallgranulat verwendet werden.Optionally, metal particles in the form of coarse grains from recycled metal granules can be used to produce the metal body.
Zur Herstellung des Metallkörpers können Metallpartikel in Form von Grobkörnern in Form von Drahtkorn verwendet werden. Drahtkorn ist ein zylindrisches Korn, welches insbesondere zum Kugelstrahlen bereitgestellt wird. Damit ist eine neue Anwendung in Form der Nutzung beim 3D-Druck zur Herstellung von Metallkörpern gegeben.Metal particles in the form of coarse grains in the form of wire grain can be used to produce the metal body. Wire shot is a cylindrical shot, which is provided in particular for shot peening. This is a new application in the form of use in 3D printing for the production of metal bodies.
Als konzentrierte Energie zum Schmelzen von Metallpartikeln in Form von Grobkörnern kann vorteilhafterweise Laserstrahlung wenigstens eines Lasers verwendet werden.Laser radiation from at least one laser can advantageously be used as the concentrated energy for melting metal particles in the form of coarse grains.
In einer Ausführungsform wird zur Herstellung des Metallkörpers über die Oberfläche der schichtweise aufgebrachten Metallpartikel geführte Laserstrahlung eines Lasers oder gleichzeitig mehrerer Laser mit Leistungen gleich/größer 1 kW und kleiner/gleich 150 kW verwendet.In one embodiment, laser radiation guided over the surface of the metal particles applied in layers is used to produce the metal body, from a laser or simultaneously from a plurality of lasers with powers equal to/greater than 1 kW and less than/equal to 150 kW.
Als konzentrierte Energie zum Schmelzen von Metallpartikeln in Form von Grobkörnern kann optional eine Schweißflamme eines Brenngases eines Autogenschweißgeräts verwendet werden.A welding flame of a fuel gas of an autogenous welding device can optionally be used as the concentrated energy for melting metal particles in the form of coarse grains.
Zur Herstellung des Metallkörpers können in einer Ausführungsform nacheinander schichtweise aufgebrachte Metallpartikel in Form von Grobkörnern, Laserstrahlung des Lasers und eine Schweißflamme eines Brenngases eines Autogenschweißgeräts verwendet werden, wobei zur Herstellung der Kontur des Metallkörpers die Laserstrahlung und der Füllung innerhalb der Kontur die Schweißflamme verwendet werden.In one embodiment, metal particles in the form of coarse grains, laser radiation from the laser and a welding flame of a fuel gas from an autogenous welding device that are applied one after the other in layers can be used to produce the metal body, with the laser radiation being used to produce the contour of the metal body and the welding flame being used to produce the filling within the contour.
Ein Ausführungsbeispiel der Erfindung wird im Folgenden näher beschrieben.An embodiment of the invention is described in more detail below.
Zur Herstellung wenigstens eines Metallkörpers mittels 3D-Druck werden nacheinander schichtweise aufgebrachte Metallpartikel in Form von Grobkörnern mit einer Korngröße größer/gleich 100 µm und gleich/kleiner 4000 µm und Laserstrahlung eines Lasers oder gleichzeitig mehrerer Laser mit Leistungen gleich/größer 1 kW und kleiner/gleich 150 kW verwendet, wobei jeweils die aufgebrachte Schicht der Metallpartikel mit der über die jeweilige Schicht geführten Laserstrahlung des Lasers so beaufschlagt wird, dass mindestens eine definiert und bestimmt umrandete Schicht entsteht. Die Metallpartikel können dazu als Schüttgut aufgebracht und anschließend zu einer Schicht eingeebnet werden. Dazu kann vorzugsweise eine Klinge verwendet werden.To produce at least one metal body by means of 3D printing, metal particles in the form of coarse grains with a grain size greater than/equal to 100 µm and equal to/less than 4000 µm are applied in layers one after the other and laser radiation from a laser or simultaneously several lasers with power equal to/greater than 1 kW and less/ equal to 150 kW is used, with the applied layer of metal particles being exposed to the laser radiation guided over the respective layer in such a way that at least one layer with a defined and defined border is formed. For this purpose, the metal particles can be applied as bulk material and then leveled to form a layer. A blade can preferably be used for this purpose.
Die Metallpartikel können in einer Ausführungsform aus recycelten Metallgranulat bestehen oder in Form von Drahtkorn verwendet werden.In one embodiment, the metal particles can consist of recycled metal granulate or can be used in the form of wire shot.
In einer speziellen Ausführungsform wird Edelstahlgranulat mit einem Korndurchmesser von gleich/größer 0,2 mm bis kleiner/gleich 0,4 mm mit einer Schichtdicke von 0,8 mm zur Herstellung des Metallkörpers verwendet. Der Laser besitzt dazu eine Laserleistung von 10 kW und einen Fokusdurchmesser von 1,3 mm. Die Vorschubgeschwindigkeit beträgt 150 mm/s. Mit einem Hatchabstand von 1,1 mm liegt die Volumenenergiedichte bei üblichen 75 J/mm3. Die Baurate beträgt hohe 500 cm3/h.In a special embodiment, stainless steel granules with a grain diameter of 0.2 mm or greater and 0.4 mm or less with a layer thickness of 0.8 mm are used to produce the metal body. The laser has a laser power of 10 kW and a focus diameter of 1.3 mm. The feed speed is 150 mm/s. With a hatch distance of 1.1 mm, the volume energy density is the usual 75 J/mm 3 . The build rate is as high as 500 cm 3 /h.
In einer weiteren Ausführungsform können nacheinander schichtweise aufgebrachte Metallpartikel in Form von Grobkörnern, Laserstrahlung des Lasers und eine Schweißflamme eines Brenngases eines Autogenschweißgeräts zur Herstellung des Metallkörpers verwendet werden, wobei zur Herstellung der Kontur einer geschweißten Schicht die Laserstrahlung und der Füllung innerhalb der Kontur die Schweißflamme verwendet werden. Der Autogenschweißkopf des Autogenschweißgeräts wird dabei an einer x-y Achse geführt. Der Laserstrahl des Lasers wird entweder mit einem Scanner oder an einer weiteren x-y Achse geführt. Die x-y Achse kann als Linearachssystem oder als Parallelkinematik ausgeführt sein. In jedem Fall werden der Laserstrahl und die Schweißflamme definiert so gesteuert über die Oberfläche der einzelnen Schichten geführt, dass der Metallkörper relatv schnell in der gewünschten Form entsteht.In a further embodiment, metal particles in the form of coarse grains applied in layers one after the other, laser radiation from the laser and a welding flame of a fuel gas from an autogenous welding device can be used to produce the metal body, with the laser radiation being used to produce the contour of a welded layer and the welding flame used to fill the contour will. The oxy-fuel welding head of the oxy-fuel welding device is guided on an xy axis. The laser beam of the laser is guided either with a scanner or on another xy axis. The xy axis can be designed as a linear axis system or as parallel kinematics. In any case, the laser beam and the welding flame are guided over the surface of the individual layers in a defined manner, that the metal body is formed relatively quickly in the desired shape.
