A sterile contact lens 3d printing method and device

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.
