Using FDM technology we have developed an outsole which is superior to traditional rubber outsoles in many ways. It is lighter in weight because of The material TPU and lattice structures which possess low weight to high strength ratio. The outsole is more breathable because of the soft TPU texture and allows airflow through the gaps of the lattice structures. The combination of 3d printing, lattice structures and TPU has made it possible. What is TPU? What is thermoplastic polyurethane (TPU)? - TPU is a highly versatile elastomer with unique properties that offers both superior performance and processing flexibility. TPU is the ideal polymer for applications in a wide variety of markets, including footwear, wire and cable, film and sheet, compounding, adhesives and specialty molded parts. TPU has been providing benefits to designers, manufacturers and end users for over 60 years. TPU is a unique type of plastic bridging the gap between rubbers and plastics. The key to TPU's
