(DE) VERFAHREN UND VORRICHTUNG FÜR DEN PULVERBETTBASIERTEN ADDITIVEN AUFBAU EINER MEHRZAHL GLEICHARTIGER BAUTEILE
Abstract:
(EN) The invention relates to a method and to device for the powder bed-based additive building up of a plurality of identical components (10), comprising the fixing of each of the components (10) on a base plate (1) by means of a retaining apparatus (2), the adjusting of a vertical position of at least some of the fixed components (10) relative to the base plate (1), such that a structural peak (11) of each component (10) is spaced apart from the base plate (1) within a predetermined tolerance range (TB), providing a powder bed (3) of a building material on the base plate (1) up to a height of the tolerance range (TB) and the layered, additive building up of material on each of the structural peaks (11) of the components (10).
(FR) L'invention concerne un procédé pour la fabrication additive, à base d'un lit de poudre, d'un grand nombre de pièces (10), comprenant la fixation de chacune des pièces (10) sur une plaque de base (1) à l'aide d'un dispositif de retenue (2), l'ajustement d'une position verticale d'au moins quelques-unes des pièces fixées (10) par rapport à la plaque de base (1), de telle sorte qu'un sommet (11) de chaque pièce (10) soit à une distance de la plaque de base (1) entrant dans une plage de tolérance (TB) prédéterminée, la fourniture d'un lit de poudre (3) d'un matériau de construction sur la plaque de base (1) jusqu'à une hauteur correspondant à la plage de tolérance (TB), et la construction additive couche par couche sur le sommet (11) de chaque pièce (10).
(DE) Verfahren und Vorrichtung für den pulverbettbasierte additiven Aufbau einer Mehrzahl gleichartiger Bauteile Es wird ein Verfahren für die pulverbettbasierte, additive Herstellung einer Mehrzahl von Bauteilen (10) angegeben, umfassend das Fixieren jedes der Bauteile (10) auf einer Grundplatte (1) mittels einer Halteeinrichtung (2), das Einstellen einer vertikalen Position zumindest einiger der fixierten Bauteile (10) relativ zu der Grundplatte (1), sodass eine Aufbauspitze (11) jedes Bauteils (10) innerhalb eines vorbestimmten Toleranzbereichs (TB) von der Grundplatte (1) beabstandet ist, dass Bereitstellen eines Pulverbettes (3) eines Aufbaumaterials auf der Grundplatte (1) bis zu einer Höhe des Toleranzbereich (TB), und das schichtweise additive Aufbauen von Material jeweils auf der Aufbauspitze (11) der Bauteile (10).
