A 3D printing system applies colored powders (e.g., primary colors, white, black, cyan, magenta, yellow, fluorescent colors, metallic) in printed polymer layers for forming a colored 3D object. The system may stabilize a powder layer or color sub-layers thereof, for example with one or more of heat, pressure, and/or high-intensity light. On each layer, powders of various colors may be sequentially deposited in a halftone pattern and stabilized, so as to create a part with a specified arrangement of colors throughout its structure. Benefits include more stable color than strategies involving jetting colored fluids. The arrangement of color on the interior of the part could provide functional or traceability benefits for specific applications. The examples allow for depositing a greater quantity of powder on each fiber base or substrate, decreasing the ratio of fiber to powder and increasing production speed.

Also provided is a method for manufacturing an electromechanical switch, which in some embodiments includes manufacturing an electrically insulating support according to the presently disclosed method for manufacturing an electrically insulating support and attaching electrically conductive elements to different regions thereof. Also provided is an electromechanical switch manufactured according to the presently disclosed method.

Multi-step method for producing a soundproof composite cover for internal combustion engines and product thus obtained, producing a cover made of thermoplastic material and insulating foam. The method uses a multiple mold with first and second cells, having male and female elements, the cells taking a first closed configuration and a second open configuration; the method including: closing the multiple mold and injecting the thermoplastic material through a channel from a hot chamber to the first cell; the thermoplastic material solidifies and the multiple mold is opened to move the solidified thermoplastic material from the first cell to the second cell; closing the multiple mold and, while a new injection occurs in the first cell, an insulating foam is injected into the second cell; and opening the double mold and, while the finished product is extracted from the second cell, a new transfer occurs from the first cell.
