Multicolored flexible wearables include a first portion having a first flexible polymer forming a toroid and including colorant(s), an exposed first outer surface, an exposed second outer surface, and a recess in the first outer surface not reaching the second outer surface. A second portion formed of a second flexible polymer fills a majority of the recess and includes colorant(s). The first and second flexible polymers have different colors and are permanently bonded together. Precious material particles may be disposed within the first and/or second flexible polymers. One or more of the colorants may have a color matching a color of the precious material particles. One method of bonding the portions includes depositing a liquid second portion into the recess and then curing it. Another method includes depositing a solid second portion into the recess and then curing a liquid layer of polymer between the first portion and second portion.

In at least one embodiment, a molding method for producing a molded article is provided. The method may include introducing polymer and fiber separately into an extruder in a first ratio to produce a first extruded material having a first fiber content and in a second ratio to produce a second extruded material having a second fiber content different from the first fiber content. The method may further include filling a first region of a mold with the first extruded material and a second region of the mold with the second extruded material. The extruded material may be formed as blanks for use in compression molding or may be introduced into an injection chamber for use in injection molding. The method may be used to form molded articles having a plurality of regions having different fiber contents.

An inductor includes a support having first and second coils formed on first and second surfaces thereof, respectively; a body embedding the support therein so that end portions of the first and second coils are exposed through first and second surfaces of the body opposing each other, and including a first magnetic part disposed in cores of the first and second coils and on upper and lower surfaces of the first and second coils, respectively, and second magnetic parts disposed on upper and lower surfaces of the first magnetic part, respectively; and first and second external electrodes formed on outer surfaces of the body to be electrically connected to the end portions of the first and second coils, respectively. The second magnetic part has a content of a hardening accelerator greater than that of the first magnetic part.

A method for manufacturing an electronic device casing having a coupling structure is provided. The electronic device casing is made of a casing material including a supportive substrate and a first thermoplastic substrate. A preliminary connecting section is formed on the first thermoplastic substrate by a hot-pressing molding process, and a molding plastic material is injected onto the preliminary connecting section by an in-mold injection process. After being cooled, the molding plastic material engages with the preliminary connecting section to form a secondary connecting section for a coupling element to couple with. Thus, the coupling structure of the electronic device casing can be directly formed during a manufacturing process without any additional procedures, thereby overall manufacturing time and costs are reduced.

Forming an adhesion layer on an imprint lithography substrate includes disposing an adhesive composition on the imprint lithography substrate and polymerizing the adhesive composition to yield the adhesion layer on the substrate, where the adhesive composition includes a compound of Formula A-1, where n is an integer and R is C.sub.1-10 alkyl.

An additive manufacturing method and apparatus is described for the printing of three-dimensional (3D) objects. The approach is based on a composite-based additive manufacturing process, except it uses commercial printing methods to achieve even higher speed and throughput. By using the invention, a prototyping and/or production process may be completed in hours rather than months, and the risks and problems of molds is eliminated. There is substantial improvement in the number and type of geometries that can be produced compared to injection molding, and the range of materials is enlarged as are the material properties. The method involves printing a substrate having at least one sheet using a printing technology, and stacking or folding the at least one sheet to form multiple layers consistent with that formed by a 3D model. The printing step is done using a printing technology such as flexography, lithography, offset, gravure, waterless printing, and silkscreen.
