Abstract: This application is generally directed to articles including cage structures and related systems and methods. The cage structures have utility in footwear and apparel (e.g., articles of clothing, braces, accessories). In some cases, the article is a footwear article. In some cases, the article is an article of apparel. In some embodiments, the article includes a textile. In some embodiments, the article includes a cage structure (e.g., comprising a polymer) attached to a substrate (e.g., a textile). In some embodiments, the interface of attachment between the substrate and the cage structure is substantially free of an adhesive.

Abstract: The present invention generally relates to methods of printing articles using three-dimensional printing and other printing techniques, and to articles formed from such techniques, including the printing of articles containing particles. Certain embodiments are generally directed to composites comprising particles (e.g., reinforcing particles), for example, rubber particles. The particles may be used, for example, to increase slip or abrasion resistance. The composites may also contain polyurethanes or other compounds, e.g., to facilitate fabrication, e.g., using three-dimensional printing and other printing techniques. Other embodiments are directed to methods of making or using such articles. For example, in some embodiments, a composite may be prepared by mixing particles (e.g., reinforcing particles) with at least a first fluid and a second fluid within a nozzle, such as a microfluidic printing nozzle, which may be used to direct the resulting product onto a substrate.

Abstract: According to at least one aspect, a manufacturing system for hybrid additive and subtractive manufacturing is provided. The manufacturing system includes a plurality of tools including a first material deposition tool configured to deposit a first material, a second material deposition tool configured to deposit a second material, and a cutting tool configured to remove at least some deposited material and a spindle configured to operate a tool from the plurality of tools that is mounted to the spindle. The manufacturing system is configured to create one or more layers of a three-dimensional object at least in part by depositing the first material using the first material deposition tool, depositing the second material using the second material deposition tool, and removing at least some deposited material using the cutting tool.
