New 3D Printing Material Expands Eyewear Design Capabilities Beyond Acetate

3D printing holds multiple advantages for manufacturing eyewear, including shorter development cycles, faster routes to market, and sustainable credentials. It also allows designers to experiment with form — offering the ability to play with complex shapes, intricate structures, and textures that are impossible to replicate with traditional production techniques. Over the last decade, this has led to the widespread adoption of 3D-printed eyewear across the industry.

As eyewear manufacturers embraced 3D printing for its exceptional design capabilities, they often encountered a practical limitation: the technology couldn't replicate the translucent aesthetics traditionally associated with acetate frames. The introduction of a new translucent material marks a breakthrough. It empowers eyewear brands to blend translucency with the unmatched design flexibility of 3D printing, allowing designers to move beyond what is possible with acetate.

The new translucent material is the result of five years of extensive trialing of over fifty different materials against the gold standard of established eyewear materials, including tests for bio-compatibility, thermal resilience, and impact resistance.

“The convergence of 3D printing technology with the advent of innovative translucent materials opens up a realm of exhilarating design possibilities for eyewear designers,” said Alireza Parandian, Head of Global Business Strategy, Wearables at Materialise. “In the past decade, 3D printing has introduced a new level of freedom that offers designers unlimited creativity to craft intricate and customized frames. Moving forward, the introduction of translucent materials to the 3D printing palette will bring a new dimension to eyewear aesthetics. These materials, with their ethereal qualities, transform eyeglass frames into works of art, offering a unique interplay of complexity and depth.”

This marriage of technology and material innovation promises to redefine the future of eyewear design, offering designers a diverse and visually captivating array of new options to enhance both their vision and style. Materialise calls upon designers to experiment with the possibility of captivating shapes, gradients, textures, and lightweight structures, all while maintaining the timeless appeal of translucent frames.

Translucent frames are not the only eyewear trend reflected in solutions Materialise will take to SILMO. Consumer preferences are moving from isolated online purchasing to in-store, personalized experiences — a shift enabled by digital technologies like Materialise’s ‘Eyewear Fitting Suite.’

Eyewear consumers increasingly want customized products and purchasing experiences. In fact, customization is one of the key drivers identified for the global eyewear market to achieve a CAGR of 8.5% by 2030. With prescription eyewear accounting for an estimated 63% of the market, this means retailers and opticians that customize their services and end products stand to gain a competitive edge.

Materialise’s Eyewear Fitting Suite enables opticians to take a detailed scan of a customer’s face to build an exact 3D digital model. The platform’s app, which can be loaded with retailer’s own collections and with those of collaborating brands, then allows the customer and optician to look at shapes, styles, colors, and size options together, leveraging both professional expertise and digital innovation to select the perfect, custom-fit frame.

Parandian says: “AI and other virtual CX tools are increasingly commonplace online. But not in-store. And that’s still where so many customers are heading to get that one-to-one professional support. However, around 1 in 4 customers who enter a shop looking to purchase new eyewear abandon their search because they are either overwhelmed by choice or can’t find the exact frame to suit their facial features. Our Eyewear Fitting Suite gives customers a better understanding of which frames perfectly match their specific face size, contours, and features and creates a new in-store shopping experience in search of the perfect frame.”

As well as answering consumer needs, the platform means retailers can offer an omnichannel purchasing journey and keep digital inventory for on-demand production — minimizing costly stock risk and potential frame wastage, therefore supporting more sustainable operations. Additionally, as printing is fulfilled at Materialise’s dedicated eyewear production facility, the largest of its kind in Europe, this frees up advisors and opticians to focus entirely on the customer.
