The resin lens has a non-planar resin surface adjoining the substrate lens along the non-planar substrate surface. A lens wafer includes a substrate wafer and resin lenses. The substrate wafer has a top surface having non-planar surface features each bordered by a planar region of the top surface and forming an obtuse angle therewith. Each resin lens has a non-planar resin surface adjoining the substrate wafer along a non-planar surface feature. A method for fabricating a wafer-level hybrid compound lens includes depositing a resin portion on a non-planar feature of a side of a substrate. The method also includes forming the resin portion into a lens on the non-planar feature.

There is disclosed a multi-material extruder and extrusion method for 3D printing, and more particularly to an apparatus and method that is adapted to extrude a wide range of materials for printing 3D structures. In an aspect, the apparatus comprises a frame adapted to receive a removable syringe or cartridge with a depressible piston in an extended position, the syringe or cartridge containing material to be extruded. An extrusion motor is under the control of an extruder logic module to determine how quickly the piston of the syringe or cartridge is to be depressed to achieve a desired rate of extrusion of the material. A flexible length of tubing connects the tip of the syringe or cartridge to an extruder nozzle, which nozzle is mounted to a stylus which may be hand-held or mounted to a chassis of a 3D printing device. A feedback signal is used to provide a feedback signal to the extruder logic module to determine the rate of extrusion of material. The syringe or cartridge may include a label containing information on the type of material in the syringe or cartridge, and one or more extrusion parameters to be used with the material in the syringe or cartridge.

A polymer composition providing optical clarity and impact resistance includes from about 40 weight percent (wt. %) to about 99.9 wt. % (e.g., 50-95 wt. %) of a continuous matrix, and from about 0.01 wt. % to about 60 wt. % (e.g., 5-50 wt. %) of a dispersed phase. The weight percentages of the matrix phase and the dispersed phase are based on the total weight of the matrix phase and the dispersed phase. The matrix phase may comprise a polypropylene polymer comprising from 0 to 7 mole percent (mol. %) of units derived from ethylene, a C.sub.4-C.sub.10 alpha olefin or combinations thereof. The dispersed phases may be a propylene/alpha olefin copolymer having from 10 mol. % to 70 mol. % of units derived from ethylene or a C.sub.4-C.sub.10 alpha olefin or combinations thereof.

A step-and-repeat imprinting mold is provided that is capable of restraining deformation of an end of a convex and concave pattern formed in a cured resin layer when the mold is removed.
