Colombian designer Neyla Coronel has introduced “Fits You!”, a capsule collection of customizable 3D printed bras made from biodegradable materials. The project, developed through the Fabricademy program, aims to solve the common problem of finding comfortable, well-fitting lingerie.
Coronel’s process combines several advanced technologies, including 3D body scanning, parametric modeling, computational geometry, and 3D printing. By scanning the wearer’s body, she creates a digital model to design lingerie that matches individual shapes and sizes.
A key feature of the bras is the use of auxetic patterns — structures that expand when stretched, offering flexibility and better adaptability to the body. Printed flat using flexible filament, these auxetic cups stretch and conform to the wearer’s shape, providing personalized comfort and support.
Each bra is composed of 3D printed auxetic cups with integrated front straps, parametric back strap panels, and connecting elements shaped like small flowers. Customers can customize several aspects, including the density of the pattern, strap length, and expansion behavior, based on their personal preferences.
After testing traditional materials like PLA and TPU, Coronel selected Balena.Filaflex, a flexible, biobased filament developed by Balena and Recreus. The material is biodegradable, compostable, and recyclable, aligning the project with sustainable fashion goals. “Working with Balena.Filaflex was a breakthrough,” Coronel said. “Its flexibility and eco-friendly properties made the lingerie not only wearable but also meaningful.”
Beyond lingerie, Coronel is continuing to explore 3D printing in fashion and design, expanding into areas such as footwear and jewelry. Her architectural background heavily influences her innovative use of materials and geometries.
“Fits You!” highlights a growing trend toward customization and sustainability in the fashion industry, offering an alternative to mass-produced garments and addressing the need for more inclusive, body-responsive design.
