Eyeglasses are not just a functional device: they are identity, fashion, style. In a sector where aesthetics and quality intertwine, the production constraints imposed by traditional materials – such as cellulose acetate – represent a challenge. It is a material loved for its visual richness and comfort, but difficult to work with: fragile under thermal stress, and not very compatible with precision finishing.The 3dnextech technology suite rewrites these limits. Through “cold” additive solutions, it opens a new production scenario for an industry that thrives on differentiation, personalization, and speed.
1. 3DFinisher™: High-Level Aesthetics, Industrial Performance
Imagine a pair of acetate glasses with a smooth, glossy, waterproof, and wear-resistant finish, achieved without dimensional alterations or risk of deformation.
The 3DFinisher™ treatment acts on the polymer’s microstructure, eliminating porosity and layer lines thanks to a process of controlled plasticization, without liquid film or direct heat. The result is a mechanically reliable and visually impeccable component, ready to walk straight from the runway to the point of sale.
2. Tattoo™: The Permanent Coloration Revolution
Personalization and branding can no longer accept compromises. With Tattoo™, coloration becomes permanent and molecular: it is not limited to a superficial coating but penetrates the structure, maintaining the piece’s resistance and flexibility.
New possibilities open up for limited collections, regional color variations, and exclusive finishes: every pair of glasses can become a unique piece, serialized directly from a file.
3. Pattern™: Texture, Design, and Functionality
Aesthetics also means touch, depth, contrast. The Pattern™ technology allows for the application of complex and repeatable textures on the surface, without molds. Whether it’s simulating natural materials or designing iconic patterns, texturization becomes a competitive asset replicable across every series, at marginal costs.
4. From Prototyping to Agile Production
Technologies like 3DNprinting and 3DNfilling allow for the creation of custom frames or parts on demand, with timeframes and costs compatible with the fashion cycle. No investment in molds, no minimum quantity constraints: the design can evolve with trends, and pilot series can go into production in days, not months.
5. Production Cells: Flexibility, Localization, Sustainability
The adoption of micro-production ecosystems – the so-called autonomous cells – enables distributed and modular production. A factory in Lucca, one in Tokyo, one in New York: all synchronized by files and process recipes. The result?
Less logistics, less CO₂, more speed.
Conclusion
The 3dnextech proposal is not a simple evolution of finishing: it is a radical transformation of the production process in the eyewear sector.
From thermal constraints to geometric freedom, from centralized production to local on-demand manufacturing, from sacrificed aesthetics to functionality and emotion fused into a single piece.
The next pair of glasses won’t just be beautiful to look at. They will also be intelligent to produce.
