Abstract
(EN)
Proposed is a 3D printer and a printing system that are capable of selectively emitting a backlight only onto a region corresponding to a single layer of a molded object being printed. The present invention comprises: a resin accommodation part in which a photocurable resin is accommodated; an LCD unit for curing the photocurable resin by irradiating the resin accommodation part with a light source that corresponds to a single layer image for molding a printed object; an LED backlight unit for providing a backlight to the LCD unit, wherein the backlight is turned on in regions in which the single layer image is displayed in conjunction with an image signal of the LCD unit, and the backlight is turned off in the remaining regions in which the single layer image is not displayed; and a control unit for controlling a light emitting region of the LED backlight unit on the basis of the image signal of the LCD unit.

L'invention concerne une imprimante 3D et un système d'impression qui sont susceptibles d'émettre de manière sélective un rétroéclairage uniquement sur une région correspondant à une couche unique d'un objet moulé qui est imprimé. La présente invention comprend : une partie de réception de résine dans laquelle une résine photodurcissable est reçue ; une unité LCD pour durcir la résine photodurcissable par irradiation de la partie de réception de résine avec une source de lumière qui correspond à une image de couche unique pour mouler un objet imprimé ; une unité de rétroéclairage à DEL pour fournir un rétroéclairage à l'unité LCD, le rétroéclairage étant allumé dans des régions dans lesquelles l'image de couche unique est affichée conjointement avec un signal d'image de l'unité LCD et le rétroéclairage étant éteint dans les régions restantes dans lesquelles l'image de couche unique n'est pas affichée ; et une unité de commande pour commander une région d'émission de lumière de l'unité de rétroéclairage à DEL sur la base du signal d'image de l'unité LCD.
