Horizons Optical & HP: Custom 3D printed eyewear

Exclusive interview with Emilio Juarez, HP’s EMEA Head of 3D Printing Sales

Horizons Optical is not your typical eyewear company. The company doesn’t simply produce glasses, rather, it develops innovative technologies and services for ophthalmic laboratories, optical chains and the optical sector on the whole. One of its most cutting edge projects is the Made4U concept, which utilizes imaging and 3D printing technologies to create fully customized frames.

On the manufacturing end of the Made4U project, Horizons Optical has turned to emerging 3D printing leader HP to leverage its Multi Jet Fusion technology. We recently caught up with HP’s EMEA Head of 3D Printing Sales, Emilio Juarez, who not only provided some insight into the Horizons Optical partnership but also testified to the quality of the 3D printed frames—which he wears every day.

3dpbm: Could you give some background on how Horizons Optical and HP started to work together?

Emilio Juarez: Horizons Optical is working with one of HP’s Service Bureau partners, World Tooling, which uses HP Multi Jet Fusion 3D printing technology. From there we connected to learn more about their interesting project.

What was the process to obtain the custom 3D printed glasses? How does the Horizons Optical customization work?

Juarez: The process begins by scanning each customer’s face utilizing 3D scanning technology called made4U and then creating a 3D model in a computer. Horizons Optical uses the 3D model to design the glasses, changing the shape of the frame in a way to suit each unique face shape. Then, the designs are sent to be manufactured with Multi Jet Fusion to the manufacturing partner. Because each design is custom-made to suit each customer’s face, Horizons Optical can produce frames which require no fitting.

What material are the frames made from?

Juarez: The material used is polyamide, a type of powder plastic that enables the geometry each patient needs.

What sets the custom products apart from other 3D printed eyewear on the market?

Juarez: The custom-made glasses ensure the perfect fit for the consumer, adapting the shape of the frame to the consumer’s unique facial features, bringing along other benefits such as optimum vision, because the lens are held in the exact right position for each person. Horizon Optical is a spin off from a larger company with years of experience in the fabrication of graduated lenses so they have a deep understanding of how to correct vision beyond providing a perfect comfort with personalized frame. 

What is HP’s value proposition in 3D printed eyewear? And the cost effectiveness of MJF in eyewear production?

Juarez: Additive manufacturing has been used for some years now to produce glasses. The big advantage that Multi Jet Fusion technology brings to the industry is the possibility make fully custom-made glasses at a lower cost. Our value proposition is to boost productivity to enable full customization at an affordable price. In addition, our Multi Jet Fusion technology has the capacity to reproduce very fine details, providing even more freedom when designing new eyewear models.

If I understood correctly, you have a pair of custom 3D printed glasses – how are they in terms of comfort/style/fit compared to more traditional frames?

Juarez: Yes, I had the opportunity to get a custom made pair of glasses by Horizons Optical. I am still amazed by how fast the process was compared to the traditional process: in just one visit, they scanned my face and I chose the style of the frames I wanted.

After they were manufactured, I was able to wear them immediately, requiring no adjustments at all. The fact that they are tailor made for my facial features makes them way more comfortable than other glasses, in part because they don’t slip down my face and I don’t have to go around pulling my glasses back to the right position again. I could also choose the colour and shape I wanted, a combo that is not always possible with traditional frames. Finally, Horizon Optical software and workflow ensured that the glasses are positioned at the perfect distance and height from my eyes, providing a perfect correction.

What are the expectations for the future of Horizons 3D printed eyewear and 3D printed eyewear more generally?

Juarez: Additive manufacturing combined with scanning software brings many benefits to the optical sector in general: superior vision by ensuring the lens is held in the right position, reduction of excess waste since frames are made-to-order, reducing the unsold frame inventory and potential weight reduction. We’ll see consumers start to really benefit and shift toward fully-tailored glasses, especially as they become more affordable.

In the past, consumers would go to the eye doctor and pick out a pair of frames, which would then be measured for fit, marking where the centre of the eye is. They’d then ship the frames off to be fitted with the correct lenses. Weeks later you’d come back in for a fitting, during which they’d adjust the arms of the frame, the nose pieces and make sure the glasses sat straight on the face.

Now, consumers are able to get their face scanned on the first visit, which is then used to design glasses that won’t need to be adjusted. We all know the struggle of an ill-fitting pair of glasses: they slip down, your eyes strain and your ears start to hurt from tensing up in order to keep your glasses in the right spot. Thanks to 3D printing, we can avoid all that by getting the fit right on the first try.


My partner and I approached David at Re3dtech with our project and were greeted with kind and caring service. Throughout the last couple of months we have placed several orders in varying size and were even able to sit down with David and the owner to discuss our needs as a small business. Through this sit down we saw their passion for assisting both small and large clients in achieving their goals. We even had a hiccup with a batch of prints that was immediately addressed and remedied with precision and care. I almost don't want to recommend these guys because I feel like I have stumbled upon a hidden gem in 3D printing services and selfishly want to keep it to myself. Jokes aside we will be continuing our business relationship with the folks there and look forward to growing our order quantities and business with their help.
Re3DTech was instrumental in helping us get our product, Stroba™, to market faster! We needed a technology that could do snap fits and looks and feels as close the injection molded part as possible, and Re3D Tech was there for us. We used SOLIDWORKS Make to get in touch originally, upload models directly, and sign an NDA directly with their excellent team. It was really simple and easy to use their quoting tool as well. Excellent prices, excellent lead times, and superior quality are perfect words to describe our experience with Re3DTech. We went through many prototypes for Stroba™, and we at Goodfriend Innovations™ use Re3DTech for our other rapid prototyping jobs to help get our additional productions out to market faster than the competition. 5 Stars
I provided RE3DTECH three laser scanned ".stl" files for 3-D printing of prototypes. I used their on-line quote and file delivery process. The file acceptance and resultant quote were returned quickly. The parts were received at the quoted time. The parts are quite complex with many holes, angles, curvatures and notches. Each of the parts came out identical to the scanned parts dimensionally and passed the form/fit/function test in the upper level assembly. RE3DTECH has a high quality business process and produces high quality products. I will use them for future prototyping projects and recommend RE3DTECH.
Re3dtech is one of the most honest and reputable companies we have done business with. We decided to look into options for getting parts made in the USA for the retail market. It was awesome to find a local company with humble staff looking to provide their services meeting our criteria, not to mention meeting the Re3tech crew face to face and checking out their operation. Peter was very honest, knowledgable about design. Peter's creative element made working with him a great pleasure. Jim's flexibility was a breath of fresh air and greatly appreciated. CentralSound is proud to scratch the surface with Made in the USA parts in the retail market now, thanks to Re3dtech. Hope to do more business with them in the future.
Re3dtech has consistently delivered the best service I have ever received in the industry. Their response time is unmatched and they always stand by their parts and quality. They regularly make me look like an all star at my job.
It is always a pleasure to have a vendor that provides quality, experience, and always shows as much care for your order, and your product as you do!
