China3D printingNet news on August 13,Lucie Trejtnarová is a graduate student in the School of Multimedia Communication of Tomas Bata University in Zlín (UTB), Czech Republic and the material manufacturer Fillamentum developed Organic 3D printingFlower shoes series.
As the name suggests, the organic shoe series aims to create sustainable footwear and accessories.The experimental sandals series integrate TPU-based Flexfill 98A, Malai (also known as coconut skin) and Piñatex (natural fabric made from pineapple leaves).3D printingOutsole.
“If I buy or manufacture a product, it is important to understand the story behind it, how it helped other people, and how it disappeared in the end,” Trejtnarová explained.
“We are responsible for each step. The shoes of the Organic series are based on a simple principle: at the end of their life, you can separate the two parts, the upper and theTaking recycled soles can be degraded, use it again. “
Organic 3D printed sandals
Trejtnarová’s inspiration for the project came from a trip to South India. During his internship at the biomaterial design studio Malai Design&Materials, Trejtnarová was introduced to Malai, a raw material that helps to form an organic footwear brand.
Malai is a 100% biodegradable material, known to be flexible, durable and waterproof. Coconut is completely natural and its texture is comparable to leather. In addition, Piñatex derived from pineapple leaf fiber (an agricultural waste) is used as a substitute for leather. Using these materials, Trejtnarová chose to make sandals to adapt to the warm and humid environment of India.

The early concept of the organic range then appeared in Trejtnarová’s UTB paper on the specific topic “3D luxury goods”. Trejtnarová explained, “I’ve been exposed to 3D model making for the first time and used it in the university.3D printingmachine,[这]It is totally a new challenge for me. “Through this contact, she was able to learn how to use3D printingMachine and make 3D models in Blender. “I continue to study SOLIDWORKS courses at the Bezalel College of Art and Design in Jerusalem,” Trejtnarová added.

Fillamentum’s Flexfill provides a series of flexible TPU filaments with high tensile strength, abrasion resistance and abrasion resistance. Flexfill 98A and Flexfill 92A have different elasticity. 98A is semi-flexible, but both are moisture sensitive. These materials are specifically designed for dynamic compression parts, seals and insoles, making them viable candidates for the Organic series.
Since Flexfill 98A is harder than 92A, it is considered more suitable for outsole prototypes. Then use Ultimaker 3 3D printingThe machine and Flexfill 98A Powder Beige produced the final outsole of the series.
The recyclability of Flexfill 98A is also an important factor for Trejtnarová. Its processability allows it to be reused, thereby preventing waste consistent with the overall organic concept. “Even Adidas plans to use thermoplastic polyurethane to produce a series of shoes.” Trejtnarová added.
With the help of Fillamentum, Trejtnarová developed the final design of the outsole by cutting the model into two parts. Then stitch the protective base to support the outsole.

Trejtnarová was pleasantly surprised by the material properties of Flexfill 98A because it was used in the prototyping and final production stages of the outsole.
A pair of Marais sandals in collaboration with Marais Design and Materials Company was exhibited at the Victoria and Albert Museum (V&A) in London. The exhibition explored the unique application of food in the future sustainable development. The exhibition ends on October 20, 2019.
