3D Printing Certification

Lucie Trejtnarová and Fillamentum build biodegradable 3D printed sandals

certification

Lucie Trejtnarová, a postgraduate scholar at the College of Multimedia Communication, Tomas Bata College in Zlín (UTB), Czech Republic, and supplies maker Fillamentum have made the Organic and natural 3D printed shoe collection. 

As its title indicates, the Natural shoe assortment was developed in an work to build sustainable footwear and equipment. The experimental sandal line integrates 3D printed outsoles from TPU-based mostly Flexfill 98A, Malai, also recognized as coconut leather, and Piñatex, a all-natural material built from pineapple leaves.

“If I purchase or make a item, it’s vital to know the story powering it, how it can assist someone, and how it could disappear,” spelled out Trejtnarová.

“We are accountable for just about every of our ways. Shoes from the Organic and natural selection are based mostly on a simple principle: At the close of their daily life, you can divide equally parts, the higher in a compost and the sole you can recycle, to use it again.”

Trejtnarová’s inspiration for the job came from a vacation to Southern India. Throughout an internship at biomaterial design studio Malai Design & Resources, Trejtnarová was introduced to the raw materials Malai that would support type the Natural footwear model.

Malai is a 100% biodegradable material recognised to be versatile, durable, and water resistance. It is wholly natural from coconut with a texture equivalent to leather-based. Furthermore, Piñatex, deriving from pineapple leaf fibre, an agricultural squander solution, is applied as an substitute for leather. With these supplies, Trejtnarová chose to create sandals to suit the heat and wet situations of India.

An early thought for the Organic range then grew out of Trejtnarová’s UTB thesis on the presented matter “3D Extravagance.” Trejtnarová describes, “I initial acquired in touch with 3D product generating and utilizing 3D printers at the College, [which] was a totally new obstacle for me.” As a result of this contact, she was able to understand how to use a 3D printer, and also make 3D versions in Blender. “I ongoing at the Bezalel Academy of Arts and Structure in Jerusalem with a SOLIDWORKS course,” Trejtnarová provides.

Trying to find a 3D printable product to help the pure fabrics in her shoe styles, Trejtnarová found out Flexfill 98A and Flexfill 92A.

Flexfill from Fillamentum provides a range of versatile TPU filaments with significant tensile energy, don performance, and abrasion resistance. Flexfill 98A and Flexfill 92A differ in elasticity with 98A being semi-adaptable, on the other hand the two are dampness delicate. These materials are developed for dynamically stressed elements, sealings, and shoe insoles, earning them a feasible candidate for the Organic and natural collection. 

As Flexfill 98A is more durable than 92A, it was considered additional suited for the outsole prototypes. An Ultimaker 3 3D printer and Flexfill 98A Powder Beige was then made use of to deliver the ultimate outsoles for the collection. 

The recyclability of Flexfill 98A was also an important component for Trejtnarová. It is processability will allow it to be employed once more, deterring squander which aligns with the total Natural principle. “Even Adidas is preparing to develop a collection of shoes from thermoplastic polyurethane next the motto ‘made to be re-made’,” Trejtnarová additional.

With assist from the Fillamentum, Trejtnarová created the final style and design of the outsole by slicing a model in two pieces. A protecting base was then stitched on to help the outsole.

Trejtnarová was pleasantly shocked at the resources capabilities of Flexfill 98A as it was utilised in both equally the prototyping and remaining production period of the outsoles. 

A pilot pair of Malai sandals produced in cooperation with Malai Layout & Resources are on display screen at the Victoria and Albert (V&A) Museum in London as section of an exhibition called “Food Larger than Plate”, which explores exceptional applications of foods for foreseeable future sustainability. This exhibition concludes on Oct 20th, 2019.
