Embodiment 1

[0034] Embodiment one structure is as follows:

[0035] See image 3 , 4 , the structure of the control main board includes the printing main control system, the X-axis servo module, the Y-axis servo module, the Z-axis servo module and the sub-control system in the prior art. The heating control circuit module is set in the sub-control system. The operating procedure of the heating system control circuit is the same as that of the existing technology. Board structure; connect the multi-color control system (PCI) interface slot row at the end of the sub-control system interface control circuit of the main board, and set more than three single-color control module boards in discrete modular packaging. Each single-color control module board is respectively installed on the slot row to ensure that the length of the signal transmission path is equal. Using the connection method of plug board and slot can realize the technical index requirements of matching symmetry of each contr...

Embodiment 2

[0045] The structure of the second embodiment is as follows (suspended walking flexible connection print head):

[0046] See Figure 9 , 10 , the difference between embodiment two and embodiment one is described in detail as follows:

[0047] The three-color printing head is equipped with three wire feeding pumps e, and the three wire feeding pumps e are arranged on the sliding base x, and a walking bracket h is installed, and a linear bearing g is installed on the walking bracket h, and is suspended under the walking bracket h The trapezoidal frame z is connected in the same way, the sliding base x is placed in the trapezoidal frame z, the bottom of the four inner inclined planes z-1 of the trapezoidal frame z is slidingly fitted with the four sides of the rectangular sliding base, and the sliding fit accuracy limits the horizontal displacement accuracy to ±0.01 mm, to ensure that the sliding base can be displaced in the vertical direction; the three wire feed pumps e and t...

Abstract

The invention discloses a control system for a stackable multi-color-head three-dimensional printer capable of realizing precision printing. A plurality of color heads of the stackable multi-color-head three-dimensional printer are used for separating hardware parts of a control loop and a heating control loop of each wire feeding pump from a motherboard to form a modular plug-board structure capable of easily ensuring the symmetry consistency; the modular plug-board structures are respectively plugged into interface slots of a heating system and a multi-color control system on the motherboard; by virtue of the symmetry consistency of technical indexes and parameter values of each wire feeding pump, multi-color fuse wires can be fused without temperature difference in a sprayer nozzle when a multi-color-head three-dimensional workpiece is printed, color wires are extruded, and high printing precision is realized. The mechanical strength of the printed workpiece reaches mechanical strength indexes of a material. Meanwhile, the control system is convenient to maintain and replace, simple in structure, stable and reliable; resources are saved, and the energy consumption and the cost are reduced.

Description

technical field [0001] The invention belongs to a stacked three-dimensional printer, in particular to a control system for a stacked colorful three-dimensional printer capable of realizing precise printing. Background technique [0002] The printing program of the stacked 3D printer in the known technology is developed on the basis of the printing program of the HP inkjet printer. During the stacked 3D printing process, the default printing material of the printing program is liquid flow. For the closing and feeding instructions of the print heads, the instruction to turn off the heating power supply of all the print heads is given only when the printing of the workpiece is finished. Therefore, the heater system in the stacked 3D printer is a separate system module, which consists of three parts: heater, temperature sensor, and heating control circuit. Temperature sensor unit, switching unit, see figure 1 , the arithmetic unit is also an integral part of the heating contro...
