Title (EN) ADDITIVE PRODUCTION OF A SHAPED BODY
(FR) FABRICATION ADDITIVE D'UN CORPS MOULÉ
(DE) ADDITIVE HERSTELLUNG EINES FORMKÖRPERS
Abstract:
(EN) The invention relates to a method for producing a shaped body. In the method, a plurality of material layers of the shaped body which lie one above the other are built up by means of an additive manufacturing process in a plurality of successive partial steps which are similar to one another, wherein in each partial step a powder is solidified to form a solid layer. The powder comprises a large number of particles, which each have at least one inner core and a shell substantially enclosing the core. The invention further relates to a powder for producing a shaped body by the method according to the invention. The powder comprises a large number of particles. The particles each have an inner core and a shell substantially enclosing the core. In this case the shells of the particles comprise material which melts below 1400 °C. The cores of the particles comprise at least one material which melts above 1700 °C. The invention further relates to shaped bodies produced by the method according to the invention.
(FR) L'invention concerne un procédé de fabrication d'un corps moulé. Selon le procédé, plusieurs couches de matériau de corps moulé reposant l'une sur l'autre sont structurées au moyen d'un procédé de fabrication additive en une multitude d'étapes partielles successives et similaires les unes aux autres, une poudre étant solidifiée pour donner une couche solide au cours de chaque étape partielle. La poudre comprend une pluralité de particules qui présentent respectivement au moins un noyau situé à l'intérieur et une coque entourant sensiblement le noyau. L'invention concerne en outre une poudre pour la fabrication d'un corps moulé par le procédé selon l'invention. La poudre comprend une pluralité de particules. Les particules présentent respectivement un noyau situé à l'intérieur et une coque entourant sensiblement le noyau. Les coques des particules comprennent un matériau fondant à une température inférieure à 1400°C. Les noyaux des particules comprennent au moins un matériau fondant à une température supérieure à 1700°C. L'invention concerne en outre des corps moulés fabriqués par le procédé selon l'invention.
(DE) Es wird ein Verfahren zur Herstellung eines Formkörpers angegeben. Bei dem Verfahren werden mehrere übereinanderliegende Materialschichten des Formkörpers mittels eines additiven Fertigungsverfahrens in einer Mehrzahl aufeinanderfolgender und untereinander ähnlicher Teilschritte aufgebaut, wobei bei jedem Teilschritt ein Pulver zu einer festen Schicht verfestigt wird. Das Pulver umfasst dabei eine Vielzahl von Partikeln, die jeweils wenigstens einen innenliegenden Kern und eine den Kern im Wesentlichen umschließende Schale aufweisen. Weiterhin wird ein Pulver zur Herstellung eines Formkörpers mit dem erfindungsgemäßen Verfahren angegeben. Das Pulver umfasst eine Vielzahl von Partikeln. Die Partikel weisen jeweils einen innenliegenden Kern und eine den Kern im Wesentlichen umschließende Schale auf. Dabei umfassen die Schalen der Partikel unterhalb von 1400°C schmelzendes Material. Die Kerne der Partikel umfassen wenigstens ein oberhalb von 1700°C schmelzendes Material. Weiterhin wird mit dem erfindungsgemäßen Verfahren hergestellter Formkörper angegeben.
