Effective shoe manufacturing with 3D printing

Shoes can be made from only two parts using 3D printing – the sole and the uppers. To produce both parts, Covestro has developed a thermoplastic polyurethane (TPU) so that the shoe can be completely recycled at the end of its useful life. (c) 2019 Covestro

The manufacture of a shoe requires a multitude of work steps, some of which are carried out by hand. This makes production time-consuming and expensive. In the finished product, various materials are sewn together and glued together, so that it is virtually impossible to recycle them by type at the end of their useful life.

Using 3D printing, shoes could be made from only two parts – upper and sole. Covestro has developed a material that enables automated production at lower cost and complete recyclability of the finished shoe. At the Formnext trade fair from 19 to 22 November 2019 in Frankfurt am Main, Germany, the company will be presenting these and other developments of its additive manufacturing programme at Booth E11 in Hall 12.1.

A powder and a filament, both based on thermoplastic polyurethane (TPU), proved to be the material of choice for meeting all the above requirements. The plastic offers high rebound and abrasion resistance and is therefore ideally suited for the production of both shoe parts.

In addition, the shoe can later be recycled in a single step, including the polyurethane adhesive used for production – an important milestone towards recycling. Old shoes are thus turned into filaments for new shoes.

Covestro, FILK Freiberg, and OUT e.V. develop flexible, conductive polymer smart textile system

As the smart textiles market continues to grow across healthcare, personal protection, sportswear, and automotive applications, developers are seeking new ways to integrate electronic functionality directly into textiles, without the rigidity and complexity of conventional wiring. To address this challenge, FILK Freiberg Institute, an independent research institution with expertise in polymer coatings for textile applications, collaborated with Optotransmitter-Umweltschutz-Technologie (OUT) e.V. The joint project, funded under the German Industrielle Gemeinschaftsforschung (IGF) program of the Bundesministerium für Wirtschaft und Energie (BMWE), focused on developing flexible, conductive polymer surfaces for next-generation smart textiles.

Covestro to exhibit solutions for a more sustainable and productive textile industry at Techtextil 2026

Covestro will present a broad portfolio of material innovations for textile coatings, adhesive films and thermoplastic polyurethanes (TPUs) at Techtextil 2026 (Hall 11.0, Booth C79). The exhibits will demonstrate how advanced solutions can enhance durability, recyclability and manufacturing efficiency across applications such as automotive, infrastructure, protective apparel and sportswear. A particular focus will be on more sustainable coating technologies, including antimicrobial systems based on INSQIN® in combination with AGXX from Heraeus Precious Metals, as well as the integration of Pontacol® thermoplastic adhesive films into Covestro’s offering.

Covestro showcases monomaterial concept in autonomous SUE People Mover

UE | STUDIOS has unveiled the fully autonomous electric minibus “Self-driving Urban E-Shuttle” (SUE), placing strong emphasis on sustainable material design. Developed within a project funded by the Federal Ministry for Economic Affairs and Energy (BMWE) and the European Union, the vehicle will begin public road testing this year. At the core of the concept is the consistent use of recyclable monomaterials to improve circularity at end of life.

Covestro and Heraeus Precious Metals collaborate to enable safer, more sustainable antimicrobial textile coatings

Laboratory tests reveal that AGXX antimicrobial surface technology from Heraeus Precious Metals is fully compatible with Impranil® PU dispersions which are part of the waterborne INSQIN® textile coating technology from Covestro, paving the way for more sustainable antimicrobial textile coatings. This discovery comes at a key moment for the textile coatings industry. As the sharing economy continues to grow, more people are coming into regular contact with high-use surfaces, creating ideal conditions for bacteria, viruses, and other microorganisms to thrive.

More patterns, less effort: the MULTI-MATIC® at Rohleder

Rohleder is one of Europe’s most modern weaving mills.
