Researchers from the European BARBARA project used food waste, polymers and 3D printing technology to manufacture door trims and dashboard front panels, as well as beam joists. Its “ingredients” include polysaccharides in corn, additives in pomegranate, and aromas of lemon and almond peel.
Four years after its establishment, from European project Barbara The creation of new materials from the following aspects has been completed Food waste, This was used to create prototypes for the automotive and construction industries. This week, they made a presentation at the Aitiip-Centro Tecnológico headquarters in Zaragoza and coordinated with the initiative.
With the help of a term called Molten filament deposition (FFF, Its English abbreviation is: Fuse manufacturing) (Most widely used in 3D printing or additive manufacturing), has obtained innovative products with industrial application value.
Specifically, they have developed prune The front of the door Dashboard, Mold and Tooling Manufacture of knots for beams and trusses and structures, such as knots for construction. These parts are processed with eight new materials, which are made into various filament spools suitable for 3D printing.
Material contains polymer The main polyester and polyamide are mixed with polysaccharides cornAnd from Granada, Pigments and fragrances lemon And shell almond, Give the material different colors, fragrances and textures, and have antibacterial and antioxidant properties.
Although they are only prototypes at present, the idea of their creators is to obtain high-quality final works, which are beginning to become reality in the real world. Electric carAnd molds and tools that are increasingly used in mixed production within the framework of European bioeconomy and circular economy.

El proyecto BARBARA (a biopolymer with advanced functions that can be used to process construction and automotive parts through additive manufacturing) 2.7 million eurosAmong them, the European Commission has made a great contribution through the Bio-based Bio-Industry Joint Venture (BBI).
Cooperation between company and university
Ten partners from Spain, Italy, Sweden and Belgium participated in the meeting. Aitiip-Centro Tecnológico is responsible for the development of the new 3D printing process and the manufacture of prototypes.
As for other partners, FECOAM has always been a supplier of food waste. Celabor, KTH and the University of Alicante have developed chemical extraction processes for functional molecules and polysaccharides. Nurel has been a supplier of commercial biopolymers. In addition to manufacturing material reels for printing, the University of Perugia in Italy has also developed materials at the laboratory level and developed Tecnopackaging at the experimental level; AccionaConstrucción and Centro Ricerche FIAT have become industrial partners responsible for verifying prototypes.
