Ming Thein Unveils Revolutionary 3D-Printed Titanium Bracelet

Independent watchmaker Ming Thein has introduced an innovative solution to a long-standing issue in wristwear: the challenge of balancing durability and comfort in bracelets. The newly developed Polymesh bracelet is touted as the world’s first fully 3D-printed titanium bracelet, featuring a unique design that combines the robustness of metal with the comfort of leather.

The Polymesh is constructed from a single piece of grade 5 titanium and consists of 1,693 individual links. This design allows it to flex and conform to the shape of the wrist while maintaining a high level of durability. Unlike traditional metal bracelets that require assembly with pins or screws, the Polymesh is printed as one continuous piece, including the clasp, eliminating the need for any post-manufacturing assembly.

Innovative Manufacturing Process

The manufacturing technique employed by Ming utilizes advanced laser sintering technology. In this process, a powder bed machine fuses microscopic titanium particles layer by layer. “Unlike conventional mesh where each individual link is made separately and then joined together, all of our links are basically sintered together as one piece,” Ming explained during a demonstration. The result is a bracelet that is both flexible and strong, retaining the appealing attributes of leather without the drawbacks associated with it.

To ensure the successful production of the Polymesh, Ming collaborated with Sisma S.p.A in Italy and ProMotion SA in Switzerland. The challenges of working with powdered titanium are significant, as this material can combust when exposed to air, necessitating processing in an inert gas environment.

The Polymesh’s design also addresses a common issue with leather straps: their inability to maintain comfort over time. “We always ask what if. What if we had a metal bracelet that really had the comfort of a leather strap?” Ming posed, highlighting the need for an adaptable solution. This bracelet not only provides the longevity associated with metal but also the pliability and comfort typically found in leather.

A Breakthrough in Watch Accessories

Ming’s journey to develop the Polymesh was fraught with challenges, including several failed prototypes. The team began with filament 3D printing to create initial models, but more than seven designs were unable to achieve the desired kinetic properties. Scaling the models proved equally complicated, as what worked at a larger scale often did not function properly at full size.

The final product features a visually striking appearance that hints at its origins in additive manufacturing, displaying a texture reminiscent of woven fabric. “It definitely feels like metal. It flows like a very, very heavy kind of chain mail,” Ming noted, emphasizing the tactile quality of the bracelet.

Consumer feedback thus far has been overwhelmingly positive. Early users describe a sensation of cognitive dissonance, noting how the Polymesh feels unlike any traditional metal bracelet due to its unique flexibility. “To experience it, to understand it, it’s best to see it in person,” Ming stated, underscoring the importance of the tactile experience.

The Polymesh is priced at CHF 1,500 and is currently available in a 20mm width, with plans for a 22mm version in the future. Additionally, Ming’s brand is exploring a stainless steel variant that may offer a different visual texture.

This development marks a significant advancement in the world of watch accessories, showcasing the potential of 3D printing technology beyond traditional applications. By creating a fully articulated bracelet with integrated components, Ming Thein has set a new standard for innovation in the industry, appealing to those who value both functionality and comfort in their wristwear.
