Embodiments of this application relate to systems and methods which allow for 3-D printed objects, such as eyeglasses and wristwatches, for example, to be customized by users according to modification specifications that are defined and constrained by manufacturers based on factors relating to the printability of a modified design.

3D fabrics have multiple layers including an outer dimensional layer of traditional fabric and a liner layer integrated with outer layer. The 3D fabrics have variable depth, typically ranging from between about 0.25 inches to about 2.0 inches. The 3D fabrics are produced from a molding process that creates the outer dimensional layer while adhering it to the liner layer. The 3D fabrics have unique visual properties which make them desirable for a variety of applications.

Methods according to the present disclosure include creating a three-dimensional effect, for example, an applique effect, that allows for the effect to be more integrated with the object to which it is added than in conventional methods. These methods can include adding the effect or applique on a surface of an object with the object sandwiched between the applique and a structure-imparting material, allowing the applique and the object it is on to move more freely and in unison together. The three-dimensional applique can be formed by applying force to the object on a side opposite to the applique such that indentations and protrusions are formed in the layered structure of the object and structure-imparting material, providing a three dimensional applique image. In other embodiments, an applique configuration may be provided separately from the object to which it is eventually to be applied.

Disclosed herein are methods, apparatus and computer program products for use in manufacturing an anatomical protective item for one or more users. Embodiments of anatomical protective items may comprise a single layer of energy controlling cells. Input data associated with one or more users is obtained. The obtained input data is processed to identify one or more energy controlling criteria for the anatomical protective item. A packing process is employed to generate each energy controlling cell in the single layer. Each energy controlling cell comprises one or more walls which extend from an upper surface of the single layer to a lower surface of the single layer. The packing process is performed at least on the basis of the identified one or more energy controlling criteria. The anatomical protective item comprising the single layer of energy controlling cells is manufactured.

A garment based of a seamless wearable structure is provided herein, wherein the structure is made by molding, spinning, dipping or spraying, and characterized by at least one attribute such as breathability, drape, stretch and recovery, dimensional stability, wash-fastness, tensile strength, tearing strength, abrasion flex and resistance, water absorbency and wrinkle recovery, which is within acceptable values according to the standards used in the garment industry.

A single-layer 3D fabric of traditional camouflage synthetic fabric with outwardly extending random hollow tunnels therein with weldments in the fabric layer intermittently along the tunnels to hold the outwardly extending hollow tunnels in place. The tunnels have variable depth, typically ranging from between about 0.25 inches to about 2.0 inches. The 3D fabric is produced from a molding process that creates the outer dimensional layer. The 3D fabrics have unique visual properties which make them desirable for a variety of applications.

Nozzle assemblies and methods of bonding fabric by jetting an adhesive are disclosed. A method of bonding fabrics with an adhesive includes receiving the adhesive from an adhesive supply into a nozzle assembly. The nozzle assembly has a valve seat, a valve stem configured to slidably move towards and away from the valve seat, and a plurality of outlet channels. The method further includes jetting the adhesive from the plurality of outlet channels onto a first fabric and applying a second fabric to the first fabric to adhere the first and second fabrics to each other.

A band includes a tubular body configured to be worn on a user's body and a pocket supported by the tubular body, where the pocket defines a cavity and has an access opening providing access to the cavity, and where the pocket is configured to removably receive an electronic module in the cavity through the access opening. An input device is connected to the tubular body and has a port exposed to the cavity of the band, where the port is configured for removable connection to a connector of the electronic module when the electronic module is received in the cavity. The input device may include a button configured to receive user input and a wireless transmitter to transmit a signal to an external device based on the user input. The input device may also include a haptic feedback mechanism for communicating haptic signals to the user.

A band includes a tubular body defining a central passage, where the tubular body is configured to be worn on a user's body such that a portion of the user's body is received in the central passage, and a housing formed of a polymer material and connected to the tubular body. The housing defines a cavity and an access opening providing access to the cavity, and the housing is configured to removably receive an electronic module in the cavity through the access opening. The housing further includes a slot in communication with the cavity, with the slot configured to permit passage of moisture away from the housing. The sides of the tubular body may also define a slope that is from 0-0.75.

A polyethylene (PE)-based fully-recyclable textile material and product formed by three-dimensionally printing PE structures onto a polyethylene textile is provided. The textile material can include one or more PE filaments being directly deposited onto a PE fabric via an FDM printing process to form a mono-material. The deposition of structures onto the PE fabric, which can form the substrate of the textile, can be used to enable changes to the mechanical properties of the fabric and/or create novel design aesthetics. Moreover, this material can be characterized by its ability to be thermally recycled, from which new PE-based products and materials may be manufactured. For example, the PE-based fully-recyclable textile material can be formed into a PE recyclate that can be melted and re-pelletized for formation of alternative PE-based fully recyclable textile materials. The PE-based fully recyclable textile material can be used in footwear and other wearable applications, as well as spacesuits, helmets, bulletproof vests, sweat-proof garments, racing suits, and so forth.
