A mild obsession with 3D printing and a disappointing visit to the optician to find a new pair of glasses led to an idea for frames that could take advantage of additive manufacturing; it could deliver infinitely customizable form and fit. There were several unique design challenges that had to be overcome in order to make 3D printed eyewear suitable for everyday use. For example, although the material was new to the optical world, it still needed the capability to be adjusted with the same use of heating machines and hand tools already available to opticians. A unique coating process also had to be developed in order to make the frames watertight. The result was arguably the world’s first 3D printed optical collection available to consumers.
