3-D Printing High-Quality, Low-Cost Optical Lenses In Under Four Hours

A team of researchers at Northwestern University McCormick School of Engineering (Evanston, Ill) are making inroads into 3-D printing optical imaging lenses. Led by associate professor of mechanical engineering Cheng Sun, the researchers developed a process to make a high-quality, low-cost lens from photo-curable resin that can be fabricated quicker than conventional methods and used in many applications for the optical and medical industries.
