Abstract: A 3D printed thermal expansion structure includes a thermoplastic material and a thermal expansion material, wherein the thermoplastic material is in a range from 50 to 90 wt % based on a weight of the 3D printed thermal expansion structure, and the thermal expansion material is in a range from 10 to 50 wt % based on the weight of the 3D printed thermal expansion structure. The thermoplastic material and the thermal expansion material are mixed to form a mixed material, and the mixed material is utilized by a 3D printing apparatus to form a solid object, and the solid object is heated to form the 3D printed thermal expansion structure. A manufacturing method of a 3D printed thermal expansion structure is provided herein.

Abstract: A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

Abstract: A transformable building block comprises a body configured to receive a connector post or other portion of another building element, an appendage movably coupled to the body, and a post configured to protrude from the body and retract into the body. Inserting a connector post into the body of the transformable building block may cause the appendage to move and the post to protrude from the body. Removing the connector post from the body may cause the post to retract into the body.

Abstract: A foldable table that provides a stable operational position in which the table legs may extend beyond the footprint of the table, and a folded, storage position in which the table legs may be tucked within the footprint of the table. An aspect provides table legs that may slide and pivot within sockets of a table top, to enable the legs to lock into the extended position and to also pivot flat against a horizontal undersurface of the table top.
