[0044] Such as figure 1 As shown, the three-dimensional printer for forming colored objects in this embodiment includes a printing head 10 , a printing platform 20 , a controller 30 and a filament tray 40 .

[0045] Wherein, the printing head 10 can move independently in three-dimensional directions relative to the printing platform 20 . The controller 30 is connected to the print head 10 and the printing platform 20 respectively. The filament tray 40 is loaded with a filament 41 , and a part of the filament 41 is disposed inside the print head 10 . Such as figure 2 As shown, the filament 41 includes a first color portion 42 and a second color portion 43 .

[0046] The three-dimensional printer of this embodiment also includes a color detection unit 50, the color detection unit 50 is connected with the print head 10, the color detection unit 50 is used to detect the color of the silk material passing through the color detection unit 50, and the controller 30 is also connecte...

[0056] The structure and function of this embodiment are basically the same as those of the first embodiment, and only the differences will be described in detail below.

[0057] Such as Figure 4 As shown, the printing head 10 of this embodiment has a melting chamber 11 and a nozzle 12 , the melting chamber 11 is used to heat and melt the filament, and the nozzle 12 is used to spray the filament melted in the melting chamber 11 on the printing platform 20 . The print head 10 also includes a color confirmation unit 70 , which is arranged between the melting chamber 11 and the nozzle 12 , and the filament passes through the fusion chamber 11 , the color confirmation unit 60 and the nozzle 12 in sequence. The color confirmation units 70 each include a color recognition sensor.

[0058] In S5, the following steps are also included:

[0059] S51: the color detection unit 50 detects the color of the passing silk material, and the detection result is the silk material of the secon...

[0064] The structure and function of this embodiment are basically the same as those of the first embodiment, and only the differences will be described in detail below.

[0065] The filament of an embodiment per se also includes a transition portion disposed between the first color portion and the second color portion.

[0066] The method of the present embodiment also includes the following steps:

[0067] T1: The filament tray continuously supplies filament to the print head, the transition part of the filament enters the print head, and the color of the transition part of the filament is a blank color.

[0068] T2: The color detection unit detects the color of the passing silk, and the detection result is a blank color silk, and obtains the fifth signal, which is transmitted to the controller.

[0069] T3: The controller drives the print head to form a waste three-dimensional object in the non-forming area.

[0070] In other embodiments, the three-dimensional printer als...

Abstract

The invention relates to a three-dimensional printer for forming colored objects and a printing method thereof. The three-dimensional printer includes a print head, a printing platform, a controller, and a wire material tray; the wire material includes a first color part and a second color part, and the three-dimensional printer also includes a color detection unit, which is connected to the print head and used for the color detection unit It is used to detect the color of the silk material passing through the color detection unit; the controller is connected with the color detection unit. The silk material includes two color parts, the first color part forms a three-dimensional object of the first color part, and the second color forms a three-dimensional object of the second color part, thereby finally forming a colored three-dimensional object, and the silk material can also include Silk in more colors. The structure does not need to replace the print head, the operation is simple, and the structure is stable.

Description

technical field [0001] The invention relates to the field of three-dimensional molding, in particular to a three-dimensional printer for molding colored objects and a printing method thereof. Background technique [0002] Three-dimensional printing, also known as additive manufacturing or layered modeling, is the process of using a digital model to process a physical object. During the processing, the printed object is built by adding materials layer by layer. [0003] The methods of three-dimensional rapid prototyping mainly include the following types: stereolithography or photocuring (Stereolithography, SLA), layered object manufacturing (Laminated object manufacturing, LOM), selective laser melting (Selective laser Melting, SLM), fused deposition modeling (Fused deposition modeling, FDM). [0004] Currently, three-dimensional (3D) printing of the FDM type is the most common on the market. The production cost of this type of 3D printer is relatively low, and the printing...
