Functional wafers by 3d printing

Abstract

A method of manufacturing an optical lens (417, 901), comprising: obtaining (S301) a transparent thermoplastic (TP) carrier (410, 1210) with at least one smooth surface; printing (S305), via a 3-D printer on the side opposite to the at least one smooth surface of the transparent TP carrier (410, 1210), at least one transparent layer (420, 1220) using a thermoplastic filament (403), each transparent layer (420, 1220) having a predetermined light filtering property, thereby forming a functional layer (420, 1220); and performing (S307) an injection over-molding process (415) to fuse bond the functional layer (420, 1220) to a thermoplastic substrate thereby forming the optical lens, wherein the at least one smooth surface of the transparent TP carrier (410, 1210) forms a smooth surface of the manufactured optical lens (417, 901).
