The production line comprises a foaming and dyeing kettle, a pressure control module, a dye separation module, a fluid liquefaction and storage module, a fluid pressurization delivery module, a fluid heating module and a dyeing circulation module. The production line integrates the functions of one-step foaming and supercritical fluid dyeing of polymer material, thereby being simple in structure, comprehensive in function, convenient to operate, high in production efficiency, good in product quality and low in cost; besides, the production line can carry out both dyeing and foaming operations, only foaming operation or only dyeing operation on polymer material.

A system for producing a homogenous extrudate powder coating composition having predetermined properties, the system comprising a color library database that is configured to store one or more input formulation data objects capable of use in controlling the inputs and operation of an electronically controlled homogenous extrudate mixer.

Such internal decoration is implemented that an object looks a target color as viewed in any direction, and that the object is colored and has image depiction in any cross-section. A method is provided for producing a three-dimensional object by extruding a build material to form a layer corresponding to each of cross-sections obtained by slicing a target object by a plurality of parallel planes, and depositing such layers in sequence so as to form the three-dimensional object. A white material 15 and one or two or more decoration materials 13 of colors other than white, which solidify wider a predetermined condition after extruded from nozzles, are used as the build material. The decoration materials 13 and the white material 15 are mixed to form the layer.

The present invention provides a synthetic resin molded product reusing plastic waste including a plurality of kinds of plastics mixed therein (such as ocean plastic trash, and hardly classifiable plastic trash in industrial waste or general waste) as raw materials, and having a high sense of design, and provides a manufacturing method thereof. The molded product is characterized by being molded with a powder of plastic waste including a plurality of kinds of plastics mixed therein, and a powder of a second material (such as a woodchip) not molten under a temperature condition of 200° C. as raw materials, and is characterized in that a large number of spots 33 different in color and/or glossiness from a base color of the molded product (deck material 31) are scattered at random on a surface of the molded product, and in that a stipple pattern is formed on the surface of the molded product.

[Problem] To provide: a model component having stable quality and having gradation; and a production method therefor

[Solution] A model component having: a first layer formed using a first material having a first color; and a second layer that covers at least part of the first layer and comprises a second material having a second color that is different from the first color. The second layer includes a region having a thickness in at least one section that is less than other sections. The region includes a section in which the first layer is exposed to the surface of the second layer.

A shaping method is provided and includes: generating a slice data indicating a cross-section of a shaped object based on a shaped object data, and shaping the shaped object. In a shaped object data preparing step, the shaped object data including multiple pieces of part data is prepared. Each piece of the part data is data indicating at least an outer surface shape of a portion indicated by the part data and a color to be colored on an outer surface. In the slice data generating step, the slice data indicating a cross-section of the shaped object is generated by setting the color of each position of the cross-section corresponding to a portion indicated by each piece of the part data, and a color of an interior of the portion indicated by each piece of the part data is set based on a color set for the outer surface.

In one example, a lighting device for an additive manufacturing machine includes an array of light sources each to emit monochromatic light within a band of wavelengths that includes a peak light absorption of a liquid coalescing agent to be dispensed on to a build material.

The present disclosure is related to a method for manufacturing slabs of artificial agglomerated stone comprising: depositing a first layer (1.1) of a first mixture (M.sub.1) onto a surface (2), wherein the first layer having a first thickness h.sub.1, creating at least one cavity (3), having a width w.sub.i and a length L.sub.i, in the first layer (1.1) of first mixture (M.sub.1), depositing a second mixture (M.sub.2) into the at least one cavity (3) of the first layer (1.1), forming a second layer (1.2) by depositing the first and second mixtures, and the second layer having a second thickness h.sub.2, compacting and hardening the second layer (1.2), wherein the method further comprises after step c) and before step d), inserting a first tool (5) at least partially into the second thickness h.sub.2 of the second layer (1.2), and actuating the first tool (5) wherein the first tool (5) is configured to stir the first wall portion (4.1) while not stirring the second wall portion (4.2).

In one aspect, methods of printing a 3D article are described herein. In some embodiments, a method of printing a 3D article comprises selectively depositing a first portion of build material in a fluid state onto a substrate to form a first region of build material; selectively depositing a first portion of support material in a fluid state to form a first region of support material; and selectively depositing a second portion of build material in a fluid state to form a second region of build material, wherein the first region of support material is disposed between the first region of build material and the second region of build material in a z-direction of the article. In some cases, the first region of support material forms a grayscale pattern and/or a CMY color pattern in combination with the first region of build material and/or the second region of build material.
