Melotte, a 3D printing company in Belgium which specializes in metals, has teamed up with a Belgium designer Patrick Hoet, to develop the first 3D Printed eyewear in titanium.
Customized versions can be delivered in a week from order. 3D scanning of the customer determines size. Orders can be placed through up market opticians.
3D Printing will level the playing field for all such optics in the future, with custom designs approaching the price of today's off the shelf specs. After all, if you can 3D print one design, why not any customization. As many have observed "With 3D Printing, complexity and variety comes for free."
Specialized software for use by opticians will need to be developed to manage the 3D model customization process. Perhaps Digital Forming can help.
