3D printing technology of silicone shoe midsole appeared in the second International Fair


Many NBA stars may throw away their shoes when changing their shoes, but they must keep the "midsole" between the sole and the shoe body. This is only 1 to 2 cm thick in the bottom part, but contains the University question. On November 5, the first day of the second China International Fair, Shanghai Trading Group made its first order, and reached an intention order of US $100 million with Dow and Schneider Electric in the industrial intelligent equipment Museum. The purchased silicone can be applied to the sole of shoes, and combined with 3D printing technology, customized shoes suitable for consumers' foot shape and natural sports can be produced.


Zhenkunhang industrial supermarket, which signed the first order, is one of the second batch of 18 "6 days + 365 days" trading service platforms of Shanghai Trading Group. It is located in Qingpu District and is a one-stop industrial supplies service platform for service manufacturing industry. "At present, 80% of our orders are online orders, aiming to achieve efficient and transparent one-stop purchase of industrial supplies and intelligent management of factory materials through digital network collaboration," Zhong Yan, director of public affairs, told dongfang.com


The silicone purchased this time is very special. The person in charge of Dow pointed to a transparent honeycomb "sole" in front of a glass display cabinet and introduced to dongfang.com: "this seemingly sole thing is actually a middle sole made of sinate 3d335 liquid silicone rubber (LSR)." It sounds very tongue twisting, and the person in charge further explained: "generally speaking, it is a liquid silicone rubber material that can be printed in 3D." This material combines the high performance and excellent processing performance of silicone elastomer, which can accelerate the sample development and customized product production, so it becomes an ideal raw material for small-scale experimental production of complex components.


"You know what? Many NBA stars may throw away their shoes when changing their shoes, but they will certainly keep their insoles, because their insoles are customized to maximize their ergonomics and improve the comfort and safety of sports. " The person in charge said. Through 3D printing technology, the midsole is made into honeycomb, which can save materials. The midsole made of liquid silica gel has no smell, will not cause bacteria growth, and is waterproof and breathable, very durable. " "The material has high transparency and can maintain stability of performance no matter what color the designer chooses." The person in charge added.


It is reported that the second China International Fair is the first time that this material and technology appear in China. Dow hopes to apply it to wider fields such as auto parts in the future, so that technology can change life.
