  • the platform unit 1 can be detached as a whole from the base plate D in order to be able to preassemble the platform unit 1 as a separate structural unit and attach it to the base plate D only afterwards.
  • the platform unit 1 not only can the printing processes that can be implemented with the 3D printing device V become more flexible. Rather, the setup of the 3D printing device V is also considerably facilitated as a result.
  • the platform unit 1 is shown in the extended position on the base plate D. In the extended position shown in FIG. 5, the platform unit 1 can be removed from the guide device 2. In contrast, the platform unit 1 is displaced along the guide rails 20 and 21 for the transfer to an intended end position according to FIGS. 1A to 4.
  • the displaceable mounting of the platform unit 1 on the base plate D also makes it easier to remove a printed component from a printing surface F provided by the platform unit 1.
  • the platform unit 1 can be displaced longitudinally along two opposite displacement directions R1 and R2 via its base carrier B, which is held displaceably on the guide rails 20 and 21 of the guide device 2.
  • the platform unit 1 can be moved into the extended position along the adjustment direction R1 by pulling on the front handle 1c. As a result, the platform unit 1 is displaced outside the pressure space R.

Abstract

La présente invention concerne en particulier une unité de plateforme (1) pour l'agencement d'un dispositif d'impression 3D (V) au niveau d'une plaque de base (D), l'unité de plateforme (1) définissant une surface d'impression (F) pour une pièce à élaborer couche par couche de manière tridimensionnelle. L'unité de plateforme (1) peut être fixée de manière détachable à la plaque de base (D) et comprend : a) au moins un dispositif de chauffage (100) pour réchauffer la surface d'impression (F) et/ou b) au moins une plaque de base frittée amovible qui définit au moins une partie de la surface d'impression (F), et/ou c) au moins un dispositif de magnétisation (140, 141a-141c) pour orienter des particules magnétiques imprimées pour la pièce.
