Title (EN) PHOTO-CURING 3D PRINTER AND 3D PRINTING METHOD
(FR) IMPRIMANTE 3D À PHOTO-DURCISSEMENT ET MÉTHODE D'IMPRESSION 3D
(ZH) 一种光固化3D打印机以及3D打印方法
Abstract:
(EN) A photo-curing 3D printer, comprising: a storage unit (1) for accommodating liquid-state photosensitive resins, and a light source (2) provided below the storage unit (1); the light source (2) is configured to be the bottom of the storage unit (1) for displaying a pattern consisting of a light shielding area for shielding light rays and a light transmitting area for transmitting the light rays by means of irradiation of the light rays with central wavelengths being longer than 405 nm and shorter than 420 nm; the photosensitive resins accommodated in the storage unit (1) are cured under irradiation of the light rays; the photosensitive resins contain photo-polymerization initiators with sensitive wavelengths being longer than 405 nm and shorter than 420 nm.
(FR) L'invention concerne une imprimante 3D à photo-durcissement, comprenant : une unité de stockage (1) pour recevoir des résines photosensibles à l'état liquide, et une source de lumière (2) disposée au-dessous de l'unité de stockage (1) ; la source de lumière (2) est configurée pour être le fond de l'unité de stockage (1) pour afficher un motif constitué d'une zone de protection contre la lumière pour protéger des rayons lumineux et une zone de transmission de lumière pour transmettre les rayons lumineux au moyen d'irradiation des rayons lumineux, les longueurs d'onde centrales étant supérieures à 405 nm et inférieures à 420 nm ; les résines photosensibles logées dans l'unité de stockage (1) sont durcies sous l'irradiation des rayons lumineux ; les résines photosensibles contiennent des initiateurs de photopolymérisation ayant des longueurs d'onde sensibles supérieures à 405 nm et inférieures à 420 nm.
(ZH) 一种光固化3D打印机,包括:用于容纳液态光敏树脂的储存单元(1)和布置于所述储存单元(1)下方的光源(2);以及,光源(2)以中心波长为大于405nm至小于420nm的光线照射配置成显示以遮挡光线的遮光区域和透过光线的透光区域组成的图案的储存单元(1)的底部;储存单元(1)中盛放的光敏树脂在所述光线照射下发生固化,所述光敏树脂中含有光聚合引发剂的敏感波长包含大于405nm至小于420nm。
