How to 3D print a lens?

The Luxexcel technology is an inkjet-based 3D print technology which builds lenses droplet by droplet. From a liquid material, small droplets are jetted to build the required ophthalmic lens shape.

The 3D printing process obtains very smooth lens surfaces without any post-processes. We are able to create very accurate lenses because we use extremely small droplets, and we are able to print rapidly because we jet many droplets at the same time.

Lens production with 3D printing

Conventional ophthalmic lens production involves multiple machining steps in which material is subtracted from a lens blank through grinding, polishing, and edging. For years this technology has been used in the ophthalmic industry. The results are good quality lenses but at the expense of high inventory, complex finishing and a significant waste of material. The alternative to this method, additive manufacturing through 3D printing, is a new concept for the ophthalmic industry.

3D printing: game changer

3D printing has already brought a revolution to a number of different industries. A frequently used example is the hearing aid industry. Within 5 years the main manufacturing technology has shifted from casting and manual finishing to 3D printing. Now, most hearing aids are 3D printed to specific customer needs. The eyewear industry is in many ways similar: custom products with a requirement for quick turnaround times at a competitive price.

By removing design limitations and offering partners the freedom to create revolutionary lens designs, the Luxexcel VisionPlatform™ will change the way ophthalmic lenses are developed.

It is not our intention to disrupt existing process and workflows, but collaborate with innovative partners to create the eyewear of the future!
