Abstract | The present invention relates to a device, for the sterile 3D printing of a contact lens, comprising: (a) at least 0.2 ml of photopolymer resin, which solidifies upon transmission from a light source; (b) a receptacle, for containing said photopolymer resin, having a transparent bottom, for allowing an external light source to transmit light into said device for selectively solidifying part of the photopolymer resin into a solidified polymer layer of said contact lens; (c) a detachable top, for covering said receptacle, with an aperture for allowing the flow of fluids into and out of said device; (d) an elevatable platform, located inside said device, serving as a build plate for the solidified layer(s) of said contact lens and (e) a conduit, attached to said platform and accessible from without said device, for allowing the flow of fluids into and out of said device.
La présente invention concerne un dispositif d'impression 3D stérile d'une lentille de contact, comprenant : (a) au moins 0,2 ml de résine photopolymère, qui se solidifie lors de la transmission à partir d'une source de lumière ; (b) un récipient, destiné à contenir ladite résine photopolymère, ayant un fond transparent, pour permettre à une source de lumière externe de transmettre de la lumière dans ledit dispositif pour solidifier sélectivement une partie de la résine photopolymère dans une couche de polymère solidifié de ladite lentille de contact ; (c) une partie supérieure amovible, pour recouvrir ledit récipient, avec une ouverture pour permettre l'écoulement de fluides à l'intérieur et à l'extérieur dudit dispositif ; (d) une plateforme pouvant être relevée, située à l'intérieur dudit dispositif, servant de plaque de construction pour la ou les couches solidifiées de ladite lentille de contact et (e) un conduit, fixé à ladite plateforme et accessible depuis ledit dispositif, pour permettre l'écoulement de fluides dans et hors dudit dispositif. |
