Abstract
(DE)
Die Anmeldung betrifft einen 3D-Drucker (1) umfassend eine ebene Aufbauplatte (4) und ein der Aufbauplatte (4) gegenüberliegendes, parallel dazu angeordnetes Belichtungselement (10), wobei der Abstand zwischen Aufbauplatte (4) und Belichtungselement (10) mithilfe einer Antriebseinheit (6) einstellbar ist und wobei die Aufbauplatte (4) und/oder das Belichtungselement (10) derart in einem mit Harz (2) gefüllten Reservoir (3) angeordnet ist, dass der an der Aufbauplatte (4) angrenzende Bereich zwischen Aufbauplatte (4) und Belichtungselement (10) von dem Harz (2) im Reservoir (3) eingenommen wird. Das Belichtungselement (10) ist erfindungsgemäß als zweidimensionale Matrix aus dicht nebeneinanderliegenden, einzeln ansteuerbaren Quantenpunkt- Leuchtdioden (11) gebildet.
(EN)
The application relates to a 3D printer (1) comprising a flat base panel (4) and an exposure element (10) which is arranged opposite and parallel to the base panel (4), the distance between the base panel (4) and the exposure element (10) being adjustable with the aid of a drive unit (6), and the base panel (4) and/or the exposure element (10) being arranged in a reservoir (3) filled with resin (2) such that the region bordering the base panel (4) between the base panel (4) and the exposure element (10) is occupied by the resin (2) in the reservoir (3). According to the invention, the exposure element (10) is formed as a two-dimensional matrix of quantum dot light-emitting diodes (11) which are situated closely next to one another and can be activated individually.
(FR)
La présente invention concerne une imprimante 3D (1) comprenant une plaque de construction (4) plate et un élément d'exposition (10) opposé à la plaque de construction (4), disposé parallèlement à celle-ci, l'écart entre la plaque de construction (4) et l'élément d'exposition (10) pouvant être réglé à l'aide d'une unité d'entraînement (6) et la plaque de construction (4) et/ou l'élément d'exposition (10) étant disposés dans un réservoir (3) rempli de résine (2), de telle sorte que la zone adjacente à la plaque de construction (4) entre la plaque de construction (4) et l'élément d'exposition (10) est occupée par la résine (2) dans le réservoir (3). L'élément d'exposition (10) est formé selon l'invention en tant que matrice bidimensionnelle composée de diodes électroluminescentes à boîtes quantiques (11) pouvant être commandées individuellement, situées tout près les unes des autres.
