How does the Luxexcel technology work?
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. Because we let the droplets merge before they are cured, we obtain 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. To learn more about our process, please refer also to our video gallery.

What is your business model?
Luxexcel provides a full turnkey solution for ophthalmic labs, this solution is called Luxexcel VisionPlatform™. This in-lab solution includes a 3D printer, consumables, design software, print process and full service and support. We provide the full turnkey solution in order to make optimal make use of the 3D print capabilities. The lab will pay on a click fee basis and will make a volume commitment to Luxexcel. The equipment remains the property of Luxexcel.

Who will have access to this technology?
Our primary customers are ophthalmic labs. We will provide them with our enabling Luxexcel VisionPlatform™ solution consisting of hardware, consumables, software and full support. Through the labs, we will provide full customization solutions to opticians and optometrists allowing them to make full use of custom lens designs and better serve their customers.

When can I have a machine?
We are currently taking orders from ophthalmic labs, if you are an ophthalmic lab and want to join us on this exciting journey, please reach out to us to discuss the possibilities.

What is the pricing for a machine?
We will not be selling machines. If you would like to have a machine in your ophthalmic lab we make them available based on a click fee model. Please contact us if you would like to discuss the possibilities for your ophthalmic lab.

What products can be 3D printed?
Initially, the focus will be on low volume high-value products, slab-offs, prisms, high diopters, multi-focals etc.

What ophthalmic lab can provide me with lenses?
For now, we deliver from our own facility for selected test market purposes only and make sure we stay aligned with the latest market trends. We have two printers installed in the US at IFB Solutions, Winston-Salem, NC and at Quest Vision Care Specialty Lab, Largo, FL.

I am an optician, can I get lenses?
We work through ophthalmic labs and our first machines are installed in the field. We could connect you to an accredited lab. If you would like to stay up to date please subscribe to our newsletter.

Can I get some lenses to test?
We do not sell lenses directly.  Our technology will be provided through selected ophthalmic labs. If you are an ophthalmic lab and would like to know more about our technology solution please contact us.

Do you provide prototyping for other industries like lighting and automotive?

All focus is on the ophthalmic market


What materials do you use?
Luxexcel developed its own UV curable material. The material is called Luxexcel VisionClear with material properties similar to common eyewear materials.

Coating & Edging

Coating compatibility
Luxexcel lenses are compatible with various coatings typically used in the ophthalmic industry. Through partner companies we are compatible with:

• Hard coats/Anti-scratch coatings
• Blue light / UV filter
• Anti-reflective coating
• Tinting
• Mirrors

We are currently developing:

• Polarization
• Photochromic

Can your lenses be edged?
Our process is compatible with both stone-based and tool-based edging processes.

Lens Design

Do you have lens design software?
To make use of the benefits of 3D printing Luxexcel has developed a lens design suite called  Luxexcel VisionMaster™ which allows ophthalmic labs to create their lens designs. The software is developed to design lenses which are difficult to manufacture and is ideal for designing specialty lenses.
