The present invention relates to a three-dimensional printer. According to an embodiment of the present invention, the printer comprises a plurality of tanks, and can manufacture a shaped product by using various colors and various materials stored in the tank.

Techniques for integrating a machine-readable matrix with a component of a mechanical structure using three-dimensional (3-D) printing are disclosed. Such techniques include generating at least one data model representing the component, and projecting a matrix pattern identifying one or more features of the component onto a selected surface portion of the component to produce a modified data model for use as an input to a 3-D printer.

A method for fabricating a colored 3D object is provided. The method includes: forming, based on layer-structure data of a target object, a layer-structure product by printing of a molding material; forming a layer-print product by printing color inks on the layer-structure product based on layer-color data; and repeatedly forming the layer-print product to provide a plurality of the layer-print products, and fabricating a colored 3D object from the plurality of the layer-print products, stacked one over another. The color inks are printed synchronously or following the formation of the layer-structure product. A system for fabricating a colored 3D object includes a processing terminal, a print head, and a drive controller. The method and system improve a dimensional accuracy and printing efficiency of the colored 3D object.

A shaping device for shaping a three-dimensional shaped object, the shaping device including a plurality of inkjet heads, which are a plurality of ejection heads, and a control unit; where at least some of the plurality of inkjet heads ejects ink to become the material for coloring; and the control unit causes the plurality of inkjet heads to eject ink so that the shaped object in which a way of coloring for at least one part is different from a way of coloring for at least other parts is shaped based on shaping data, which is data indicating shape and color of the shaped object, and coloring system designating data, which is data indicating the way of coloring for at least one part of the shaped object.

A process for fabricating a powder coating composition having a desired color from solid input filaments. A plurality of solid input filaments is fed to a mixer in accordance with an input formulation for a color. The input filaments are liquefied at the mixer, and the liquefied input filaments are combined together in the mixer into an extrudate mixture. The extrudate mixture is removed from the mixer, solidified, and then the solidified extrudate mixture is milled into a powder.

A three dimensional printing system which creates a multiple color printed structure which may be e.g. an inflatable likeness. The printing is done with a stretchy material such as silicone and is printed in layers of different color in order to match the designed likeness colors. In preferred embodiments, the 3d printing is done inside a gel suspension with a specialized print head which dispenses silicone in layers of color to produce the final desired color of silicone in the particular locations as determined by the avatar or likeness design.

A process and system for rapidly fabricating small batches of powder coating compositions having desired colors from one or more solid input filaments. An additive manufacturing filament fabricator feeds one or more single-color solid polymer input filaments into a heated mixer in accordance with an input formulation to be liquefied and mixed to produce a homogenous extrudate mixture. The extrudate mixture is solidified on an extrudate receiving platform and is then comminuted by an extrudate mill into a finished powder coating composition having a desired color.

It discloses a high-speed reciprocating color 3D printer; said printer includes a nozzle assembly that is horizontally movable in one direction, preferably an X-axis direction, and a workbench that is vertically movable in the Z-axis direction. A plurality of spray pipes are mounted on the nozzle assembly, wherein, the spray pipes contains a variety of liquid printing materials, including white matrix material and a variety of color materials. In a movement process, each spray pipe works separately. The white matrix material is used to print out the image firstly, especially the darker area of the image, and then the color of the image is printed through the color material, and the resulting image partially protrudes outward.

A slicing and printing method for colour 3D physical model with protective film is provided. The method executes a slicing process to colour 3D object data for generating multiple layers of object slice data and colour slice data, generate multiple layers of body slice data and multiple layers of protection slice data according to multiple layers of the object slice data, manufacture multiple layers of body slice physical models according to multiple layers of the body slice data, color each layer of the manufactured body slice physical model according to the same layer of the colour slice data, and use light-transmissive print materials to manufacture multiple layers of protection slice physical models according to multiple layers of the protection slice data. The method can effectively make the manufactured colour 3D physical model be with light-transmissive protective film, and prevent the colour 3D physical model from decolorization.

A printing method for color compensation adopted by a 3D printer (1) having a 3D nozzle (121) and a 2D nozzle (122) is disclosed. The printing method includes following steps of: controlling the 3D nozzle (121) to print a slicing object (2) of the 3D object upon a printing platform (11) according to a route file; controlling the 2D nozzle (122) to perform coloring on the printed slicing object (2) according to an image file; controlling the 2D nozzle (122) and the printing platform (1) to rotate relatively for creating an angular transposition between the 2D nozzle (122) and the printing platform (1) after the slicing object (2) is colored completely; and, controlling the 2D nozzle (122) to again perform coloring on the colored slicing object (2) after the 2D nozzle (2) and the printing platform (11) rotated relatively.
