HP, Decathlon and Lonati Group presented a revolutionary shoemaking concept at the ITMA trade show in Milan on June 14, 2023, aiming to demonstrate the innovative application of 3D printing technology in the field of footwear manufacturing .
△3D printed shoes jointly created by HP, Decathlon and Lonati Group
As we all know, the traditional shoemaking process involves a large number of parts, adhesive materials and manual labor. By using 3D printing technology, more advanced manufacturing technology will completely change the way of traditional shoemaking. This innovation is seen by Hewlett-Packard, Lonati Group and Decathlon as a model for the future of the shoe industry.
△HP Jet Fusion 5200 series promises breakthrough economics, productivity and applications
In this shoemaking concept, they feature custom footwear from Lonati combined with midsoles and outsoles manufactured by an HP Jet Fusion 5200 3D printer. Lonati's XT-MACHINE and double-cylinder E1530XS knitting machines can produce uppers with single or double layers of fabric, allowing the upper to be integrated with the midsole for greater comfort, lightness, performance and quality.
△Ultrasint TPU is a fully functional flexible material ideal for wear-resistant and resilient parts
To ensure optimum performance, the midsole and outsole feature Ultrasint TPU01, a material developed by HP in collaboration with BASF. This versatile thermoplastic polyurethane powder is known for its excellent shock absorption and flexibility.
Through this cooperation, HP, Lonati Group and Decathlon hope to emphasize the following points to share the advantages of 3D printing and digital knitting in industrial-grade manufacturing:
●Personalized customization: This shoe allows consumers to personalize it according to their own preferences and needs to meet their unique needs.
●Recyclability and repairability: The manufacturer adopted a glue-free assembly method, so that the shoes can be easily repaired when damaged. The cushion and upper can be separated, which means that the shoe can be repaired in a targeted manner without the need to discard the entire shoe, reducing resource waste.
●Local Production: The shoe's manufacturing process supports local production, reduces transport emissions and contributes to the local economy.
●Flexibility: The flexibility of the manufacturing process enables inventory life to be optimized and on-demand production to reduce waste. This means products are only made when needed, avoiding overproduction and overstocking issues.

Philip Seille, Head of Discovery at Decathlon, said: "We are delighted to be partnering with HP's personalization and 3D printing business and the Lonati Group on this project, which demonstrates our commitment to sustainable development. By harnessing the potential of 3D printing, we are To revolutionize shoemaking and provide consumers with bespoke, recycled and locally produced footwear."
Multi Jet Fusion technology is ushering in a new era of sustainable and innovative manufacturing. We are proud to partner with Decathlon to demonstrate the role of 3D printing in facilitating more sustainable There is great potential in terms of sustainable manufacturing methods. Lonati Group’s expertise in shoe upper technology is a perfect fit with our shared sustainability values. Working together is really inspiring.”
