To gain a deeper understanding of the companies driving this exciting evolution, we recently had the privilege of interviewing a key trailblazer in the industry: Hoet. Headquartered in Belgium, Hoet has established itself as a leading provider of avant-garde 3D printed eyeglass frames. We sat down with its visionary founder, Bieke Hoet, for an in-depth discussion about the company’s operations, its rich history, and its pioneering spirit in leveraging additive manufacturing.

3DN: Could you please introduce yourself and share your connection with additive manufacturing?

My name is Bieke Hoet, and I am the proud owner of Hoet, a distinguished Belgium-based design office. We specialize in offering high-end freelance design services tailored specifically for the eyewear industry. Beyond our design consultancy, I am also the founder of two truly iconic eyewear collections: Hoet Couture and Cabrio. Our journey into innovation began in 2014 when, driven by an unwavering passion for pushing boundaries, we proudly launched Hoet Couture and Cabrio eyewear. These collections were groundbreaking, marking a significant milestone as the industry’s very first fully 3D printed eyewear lines. This commitment to additive manufacturing stems from our belief in its revolutionary potential to redefine what eyewear can be, combining aesthetics with unparalleled functionality and comfort.

3DN: What is Hoet, and how did the idea of creating the company come about?

Hoet is far more than just an eyewear company; it is a family-owned enterprise deeply rooted in a rich legacy within the eyewear industry. My personal connection extends back generations, as I represent the sixth generation of my family to dedicate their expertise and passion to eyewear. Our storied heritage dates back to 1885, a time when the first traces of Hoet retail optics can be found, serving the community with optical solutions. This long-standing tradition provided a strong foundation, but it was my father who truly pioneered a new direction. In 1987, he became the first Hoet to venture beyond the traditional confines of optical retail, daring to embark on the ambitious journey of creating original eyewear designs. At that pivotal time, I was still pursuing my studies, observing his innovative spirit from afar.

I was fortunate to grow up with young, forward-thinking parents who instilled in me a sense of innovation and opportunity. Upon completing my studies in 1997, I eagerly joined my father. Together, we launched the Hoet design office, marking a new chapter for our family business. This venture allowed us to offer specialized eyewear design services to a global clientele of prestigious customers. With our unique expertise and deep understanding of the eyewear market, we were able to meet a high level of demand, crafting distinctive and innovative designs that resonated with our clients worldwide. This blend of generational experience and a constant drive for innovation has always been at the heart of Hoet’s identity, eventually leading us to embrace the transformative power of additive manufacturing.

3DN: When did Hoet begin utilizing additive manufacturing, and what specific advantages does this technology offer for the company and its customers?

To truly remain at the forefront of our customers’ minds and to continuously capture their imagination, relentless innovation is paramount. At Hoet, this principle is deeply embedded in our design philosophy. A critical element of our creative process involves extensive research into novel materials and cutting-edge technologies. These new advancements consistently inspire us, prompting us to explore how we can combine them with traditional craftsmanship to forge truly groundbreaking products. This blend of old and new is essential for creating eyewear that is both timeless and ahead of its time.

My initial encounter with 3D printing technology was through dental applications. I vividly remember observing the incredible precision and personalization capabilities of the technology used for oral prosthetics. A thought immediately struck me: “If this technology is robust and precise enough to be safely and effectively used inside a person’s mouth, why wouldn’t it be perfect for something worn on the face?” This realization was the spark that ignited our extensive journey into additive manufacturing. What followed were five years of intensive research, substantial investment, and tireless experimentation. This dedicated effort culminated in the momentous launch of our Hoet Couture and Cabrio eyewear collections in 2014, marking our official entry into the world of 3D printed eyewear.

The advantages that additive manufacturing brought to Hoet were profound and multi-faceted. Firstly, it offered unparalleled design freedom, allowing us to create complex geometries, intricate lattice structures, and organic shapes that would be either impossible or prohibitively expensive to produce using conventional manufacturing techniques. This expanded our creative palette immensely. Secondly, it enabled an unprecedented level of customization. We could tailor frames to individual facial anatomies with greater precision, offering various lens and bridge sizes to ensure optimal comfort and fit for each wearer. This bespoke approach elevates the customer experience significantly. Thirdly, 3D printing allows for rapid prototyping and iterative design, drastically reducing the time from concept to final product. This agility ensures we can quickly respond to market trends and continually refine our designs. Furthermore, the technology facilitated the use of advanced materials with desirable properties, such as lightweight yet durable polymers and even surgical-grade titanium, enhancing both the comfort and longevity of our frames. Finally, additive manufacturing often leads to less material waste compared to subtractive methods, aligning with more sustainable production practices. These combined benefits have not only transformed our design capabilities but also allowed us to offer truly unique, high-quality products to our discerning clientele.

3DN: Can you elaborate further on Hoet’s 3D printed product line, specifically the Hoet Couture and Cabrio collections?

Our flagship Hoet Couture collection is a prime example of Belgian craftsmanship meeting cutting-edge technology. Each frame in this collection is meticulously manufactured in Belgium, reflecting our commitment to quality and local production. The frames themselves are crafted from surgical-grade titanium, a material chosen for its exceptional properties: it is incredibly lightweight, remarkably strong, corrosion-resistant, and hypoallergenic, making it ideal for direct contact with the skin and ensuring maximum comfort for the wearer. A defining characteristic of the Hoet Couture collection is the innovative open structure of the front of the frame. This intricate design varies significantly from model to model, showcasing the immense design freedom offered by 3D printing. Creating such complex, airy structures with only classic, traditional production techniques would be an almost insurmountable challenge, highlighting the unique advantage of additive manufacturing. This open design not only contributes to a distinctive aesthetic but also significantly reduces the weight of the frames, enhancing wearability.

For the ultimate level of comfort and a personalized fit, these glasses are thoughtfully designed to be available in a wide array of lens and bridge sizes. This extensive customization ensures that each individual can find a frame that perfectly suits their facial structure, minimizing pressure points and maximizing stability. Furthermore, all Hoet Couture glasses are equipped with adjustable temples, allowing for fine-tuning to achieve an optimal and secure fit behind the ears. This attention to detail in customization and comfort underscores our dedication to creating not just beautiful, but also supremely functional eyewear. Currently, our Hoet Couture collection boasts 17 distinct models, and each of these models is further available in various combinations of nose and lens sizes, offering an unparalleled selection for our discerning customers. This extensive range demonstrates the versatility and scalability that 3D printing brings to our design and production processes, allowing us to cater to diverse aesthetic preferences and anatomical requirements.

While Hoet Couture focuses on surgical titanium, our Cabrio eyewear collection also harnesses the power of additive manufacturing, often utilizing advanced polymers like polyamide. This allows for an even broader range of colors, textures, and design possibilities, catering to different aesthetic tastes and functional requirements. Both collections embody our core philosophy: to push the boundaries of eyewear design through innovation, offering products that are not only visually stunning but also engineered for superior comfort and durability, all thanks to the transformative capabilities of 3D printing.
