The manufacturing of eyeglasses is a great example of customized mass production. Its globalization results in high data and product traffic, which can only be economical if the process allows a 100 % first time lens-frame fit. TH Köln developed a machine which prints viscoelastic polymer structures on machined glass edges. This method allows a five times lower accuracy in manufacturing and improves results in mechanical tension, optics and lens fit. It has shown to be highly successful with great potential in additional sectors.
