Problems solved by technology

[0004] Based on this, in order to solve the problem that the color 3D printer in the traditional technology is completely independent of the mechanical structure for coloring and printing control and the mechanical structure for shaping, which leads to the excessively long printing time caused by the large movement space during the coloring and printing process, For the technical problem of low inkjet printing efficiency, a method and device for analyzing the driving signal of exterior shaping, and a color 3D printer are proposed.

Embodiment 1

[0171] In the present embodiment, the mechanical structure of the color 3D printer is the first mechanical structure, and the core device (jet printing device) of the color inkjet printer in the prior art is installed on the frame of the FDM color 3D printer, and discarded Toner carriage that acts as the X-axis motion mechanism. The spatial coordinates of 3D modeling and coloring printing are named in Table 1. The mechanical structure of coloring printing shares the X-axis and Y-axis of 3D modeling, that is, the X-axis and Y-axis of 3D modeling and coloring printing are both mechanically Shared, but they are controlled alternately in electrical control, and both the X-axis and the Y-axis are equipped with stepper motors.

[0172] In the color 3D printer of this embodiment, in the printing stage, the inkjet head or the target physical model moves horizontally along the X-axis or the Y-axis to complete the coloring and printing. When the i-th (i=1, 2, 3,...,n) layer of the targ...

Embodiment 2

[0191] In this embodiment, the mechanical structure of the color 3D printer is the second mechanical structure. The inkjet device that can match the DC motor in the existing color inkjet printer is installed on the frame of the FDM color 3D printer, and the function as Carriage holder for X-axis motion mechanism. The space coordinates of 3D modeling and coloring printing are named as shown in Table 1. The mechanical structure of coloring printing shares the X-axis of 3D modeling, that is, the X-axis of 3D modeling and coloring printing is shared mechanically, but in terms of electrical control But it is controlled alternately, and the X-axis is equipped with a stepper motor. The Y axes of 3D modeling and coloring inkjet printing are Y1 axis and Y2 axis respectively. They are completely independent and have no coupling relationship with each other. The Y1 axis and Y2 axis are equipped with stepper motors and DC motors respectively.

[0192] As shown in Table 1, the difference ...

Embodiment 3

[0204] In this embodiment, the mechanical structure of the color 3D printer is the third mechanical structure, and the spatial coordinates of the 3D modeling and coloring inkjet are named as shown in Table 1, and the X axes of the 3D modeling and coloring inkjet are respectively X1 axis and The X2 axis is completely independent and has no coupling relationship with each other. The X1 axis and X2 axis are equipped with stepping motors and DC motors respectively; the coloring and printing mechanical structure shares the Y axis of 3D modeling, namely 3D modeling and The Y-axis of coloring inkjet printing is shared mechanically, but it is controlled alternately in electrical control, and the Y-axis is equipped with a stepping motor. The inkjet device that can match the DC motor in the existing color inkjet printer is installed on the frame of the FDM color 3D printer, and the ink holder that acts as the X2 axis movement mechanism is retained.

[0205] In the color 3D printer of th...

Abstract

The embodiment of the invention discloses a method and a device for analyzing outline molding drive signals and a colorful 3D printer. The outline molding drive signals are pulse signals used for driving an X-axis stepping motor and a Y-axis stepping motor corresponding to the molding link when the outline of the outermost circle is molded in the process that the colorful 3D printer conducts molding in a layer-by-layer stacking manner in the molding link so as to gradually form a target real object model. The method comprises the steps that target mechanical parameters are determined; moldingdrive pulse signals sent by a molding device when the process is conducted on the outer circle of any 3D printing layer in the layer-by-layer 3D printing process are collected, wherein the molding drive pulse signals are used for driving the X-axis motor and the Y-axis motor corresponding to the molding link; and according to the molding drive pulse signals and the target mechanical parameters, the outer circle path corresponding to the 3D printing layer is calculated. By adoption of the method and the device for analyzing the outline molding drive signals and the colorful 3D printer, the inkjet time needed in the colorful 3D printing inkjet link can be shortened, and the inkjet efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a method and device for analyzing driving signals for external contour shaping, and a color 3D printer. Background technique [0002] Fused Deposition Modeling (FDM for short), also known as Fused Deposition Modeling, is a molding method that does not use lasers. The FDM molding system mainly includes extrusion head, wire feeding mechanism, motion mechanism, heating studio, working table and other parts. The nozzle is controlled by the computer for XY-axis linkage scanning, and the wire is heated to slightly higher than its melting point in the nozzle. The spray head ejects the molten material during the scanning motion, rapidly cools to form a processing layer, and is firmly connected with the previous layer. In this way, layers of scanning superposition form a spatial entity. [0003] At present, the objects printed by FDM 3D printers on the market have only one ...
