Articles of footwear and apparel having a three-dimensionally printed feature

This describes a shoe upper that is mostly made from a specific type of thermoplastic material, either as a textile or a film. A three-dimensionally printed feature, also made from substantially the same thermoplastic material, is directly attached to this upper. This printed feature can be designed to have varying properties, such as stiffness or color, across its structure.

Why it matters: Since 2020, additive manufacturing technologies have advanced significantly, making it more feasible to precisely control material properties and print directly onto flexible substrates. This could make the specialized 3D printing required for this invention more accessible and effective now.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSpecialized 3D printer, material science expertise
