FOOTWEAR ASSEMBLY METHOD WITH 3D PRINTING

Smart overview of the Invention

The patent application outlines a novel method for assembling apparel, specifically footwear, using three-dimensional (3D) printing directly onto fabric materials. This technique involves designing a 3D pattern, positioning the fabric on a 3D printing tray, printing the material directly onto the fabric, curing the printed material, and then removing the finished product from the printer. The process allows for seamless integration of 3D-printed components with traditional fabric materials.

Field of Application

This innovation applies to various types of apparel and equipment, with a particular focus on footwear. It extends to any article of clothing that can benefit from 3D printing on fabrics such as textiles, natural and synthetic fabrics, knits, woven and nonwoven materials, meshes, leathers, polymers, rubbers, and foams. The method eliminates the need for a release layer or perfectly flat surfaces during printing.

Detailed Process

The method includes designing 3D patterns for different parts of an apparel item. For footwear, this involves creating patterns for both the upper and sole components. The process includes positioning parts on a tray for flat printing, aligning them with designed patterns, printing materials directly onto these parts, curing them, and final assembly. This approach allows for precise customization and integration of multiple materials.

System Components

The system comprises various technological components such as computer-readable media encoded with software for storing and executing print patterns. It involves a print server connected to a 3D printer device capable of handling multiple sequences of printing steps. The printer features trays for holding fabric surfaces and ultraviolet lights for curing printed materials.

Applications Beyond Footwear

While primarily focused on footwear, the disclosed methods can be applied to any apparel or equipment that benefits from 3D printing technology. This includes hats, shirts, jackets, athletic gear, and more. The versatility of this method makes it applicable to both athletic and non-athletic wearables.
