Abstract[German]
Die Erfindung betrifft eine Vorrichtung (1 ) in Form einer Pulverbettanlage zur additiven Fertigung von Werkstücken umfassend einen 3D-Druckkopf-Träger (3), welcher eine Mehrzahl an 3D-Druckköpfen (4, 5, 6) zum Aufbringen verschiedener pulverförmiger 3D-Druck-Materialien trägt. Der 3D-Druckkopf-Träger (3) ist mittels zwei als Linearführungen (7, 8) ausgebildeten Magnetlagerungen verschiebbar gelagert. Es liegt dabei ein Mindestabstand (a) zwischen einem 3D-Druckbereich (11 ) und den als Linearführungen (7,8) ausgebildeten Magnetlagerungen zur Vermeidung von Wechselwirkungen zwischen dem pulverförmigen 3D-Druckmaterial und den Magnetlagerungen (7,8) vor.[English]
The invention relates to a device (1) in the form of a powder bed system for the additive manufacturing of workpieces, comprising a 3D printhead support (3) which supports a plurality of 3D printheads (4, 5, 6) for applying different powder 3D printing materials. The 3D printhead support (3) is translatably mounted by means of two magnetic bearings in the form of linear guides (7, 8). There is a minimum distance (a) between a 3D printing region (11) and the magnetic bearings in the form of linear guides (7, 8) in order to avoid interactions between the powder 3D printing material and the magnetic bearings (7, 8).[French]
L'invention concerne un dispositif (1) sous la forme d'un système de lit de poudre pour la fabrication additive de pièces, comprenant un support de têtes d'impression 3D (3) qui supporte une pluralité de têtes d'impression 3D (4, 5, 6) destinées à appliquer différents matériaux d'impression 3D en poudre. Le support de têtes d'impression 3D (3) est monté en translation au moyen de deux paliers magnétiques sous la forme de guides linéaires (7, 8). Il existe une distance minimale (a) entre une région d'impression 3D (11) et les paliers magnétiques sous la forme de guides linéaires (7, 8) afin d'éviter des interactions entre le matériau d'impression 3D en poudre et les paliers magnétiques (7, 8).
