The jewelry brand Eternha combines the traditional materials of the jewelry industry and technology, such as natural hard stones, precious and non-precious metals, with gold-based hi-tech polyamide materials used in large industrial plants.
“It’s a new project, unprecedented,” said Eternha founders Stefano Massimilliano Maragoni and Chiara Cistriani. “50% of our investment is focused on product quality. Others are innovation, environmental sustainability and the search for harmony between materials and colors.”
Windform GT’s precision material has been used to manufacture components for Eternha Men’s Aquilha, Falcho, Lupho and Cobrha bracelets. Selective laser sintering, a legacy laser-powder fusion technology, is part of this process.
The objects created using this technique are very small, with Maragoni stating that they will be around 10-12 mm as an average size, the collaborator said: “The shapes vary from parallel to sphere and cylinder , with different designs.”
The consistency of the final part to the design is the best feature of the Eternha additive manufacturing. Cistriani and Maragoni say: “The 3D printing process of selective laser sintering guarantees complete control of the concept.”
Further, the co-owners added: “Our jewelry is sold exclusively online and is customized with wrist measurements entered by customers. Ensuring the ultimate grip, the bracelet is unique to the one seen online, so it’s important.”
Eternha has worked with CRP Technology, an Italian company that for the past two decades has been providing components for major industries such as sports, aerospace and automotive.
Cistriani and Maragoni say: “We like the idea of combining our jewelry with non-destructive objects, made of materials used for extreme applications and work, something ‘eternal’. Thanks for the collaboration with CRP Technology, we discovered something extraordinary, polyamide material, polyamide composite material, glass fiber.
