A method of printing a three-dimensional color object having a contoured surface onto a substrate includes printing color ink layers and structural ink layers. A color ink layer is printed onto the substrate. Structural ink layers are printed onto the color ink layer to build the three-dimensional shape of the object. The contoured surface is formed from varying the heights of pixel columns in the printing information. The heights of the pixel columns may be varied by printing different numbers of layers in adjacent columns or by printing the same number of layers in adjacent columns where some pixels in a column have different thicknesses than other pixels in the column.

Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

The present invention relates to a sensing device (10) designed for being applied on a first flap (11) and on a second flap (12) of an opening (13) arranged in a wearable item (14). The sensing device (10) comprises: a triggering element (20) arranged on the first flap (11) of the opening (13) and comprising an activating component (23); a switch element (30) arranged on the second flap (12) of the opening (13) and comprising a sensing component (33); the sensing component (33) being designed for emitting an electrical output signal when it is put in a predetermined mutual position with respect to the activating component (23). According to the invention the triggering element (20) is provided with at least one alignment component (22; 22A, 22B) designed for interacting with a corresponding alignment component (32; 32A, 32B) of the switch element (30) so as to autonomously and automatically put in said predetermined mutual position the activating component (23) and the sensing component (33) when the first flap (11) is drawn close to the second flap (12), or viceversa. The invention also relates to a closure device comprising said sensing device (10) and to a method for manufacturing said sensing device (10).

A method and system are disclosed. A method of printing onto a base having an upper surface spaced from a lower surface by a base thickness includes dispensing a yarn from a nozzle of a printing system and selectively attaching the yarn to a first attachment region. The step of dispensing the yarn includes dispensing a heat-moldable material and a melt-resistant material. The step of selectively attaching the yarn to the first attachment region includes moving the nozzle into the first attachment region. The step of moving the nozzle into the first attachment region reduces the base thickness by a prodding distance. The heat-moldable material bonds to the first attachment region.
