Perhaps, in conjunction with being applied to above-mentioned arbitrary related embodiment, further, embodiments of the invention can also be that described color three dimension printer also comprises three consumptive material spray booth stepper motors; Each described consumptive material spray booth stepper motor is fixedly set in described installing rack respectively, and fixes described consumptive material spray booth respectively, is used for the described consumptive material spray booth of control and moves along three orthogonal direction steppings respectively; That is to say that described color three dimension printer comprises the stepper motor of X, Y, three directions of Z axle, can be referred to as X-axis stepper motor, y-axis stepper motor, Z shaft step motor, thereby can control the direction of whole consumptive material nozzle; For example, nozzle by the motor of X, Y, three directions of Z axle, is adjusted the position of consumptive material spray booth below spray booth, thereby adjusts position and the direction of consumptive material nozzle.Like this, the consumptive material nozzle can carry out 3D and print in a three-dimensional spatial area in its optional position.And for example, this example also arranges an objective table for the carrying printing objects, and this objective table is fixedly set in described installing rack.
For example, as shown in Figure 2, in the described color three dimension printer, electric blender 301 is installed on support platform 302 tops, its shaft passes support platform, link the mixing part that is positioned at consumptive material spray booth inside, consumptive material stepper motor 101, consumptive material stepper motor 103 are installed on support platform 302 tops, consumptive material spray booth 303 is installed on support platform 302 belows, consumptive material nozzle 304 is arranged at consumptive material spray booth 303 belows, the color three dimension printer is realized printing at objective table 306, and the object 305 of printing places on the objective table 306; Thermocouple 307, heating tube 308 insert consumptive material spray booth inside respectively.Consumptive material 201,202,203 is not shown in consumptive material stepper motor 101,102(Fig. 2 respectively), under 103 the driving, enter consumptive material spray booth 303, through heat fused, stir after, from the ejection of consumptive material nozzle, realize that 3D prints.
In conjunction with being applied to above-mentioned arbitrary related embodiment, further, embodiments of the invention can also be, described color three dimension printer also arranges a control system, its set handling unit, and the electric blender control module that is connected with described processing unit respectively, heating tube control module, thermocouple control module and each step motor control unit, be respectively applied to the control instruction according to described processing unit, the described electric blender of corresponding control, described heating tube, described thermocouple, each described stepper motor; Particularly, what stepper motors are arranged, just the corresponding step motor control unit that equal number is set, corresponding control one by one.Described processing unit is used for receiving outside file to be printed information, generates control instruction, sends to each corresponding control module respectively.Preferably, described control system also comprises the color scheme map unit that is connected with described processing unit, be used to described processing unit that predefined color scheme is provided, according to described file to be printed information and described color scheme, generate described control instruction by described processing unit.For example, the user can be in color scheme map unit self-defined its preferred colors, and for example, the user can adjust color scheme in the color scheme map unit according to the printing effect in early stage.
For example, preferred, a hardware plan as shown in Figure 3, Chip1 is ATMEGA16U2-mu, and Chip2 is ATMEGA2560-16U, and ATmega2560 is as CPU, and the ATmega16u2-mu of low side belongs to attached chip, is used for the conversion chip with usb circuit, the concrete connection as shown in Figure 3.Because be the printing technique that adopts usb communication in the present embodiment, also be that Gcode finally carries out transfer of data by the communication mode of USB.The code that the notice machine was carried out when G-code was printing, printing is preceding by stl file generation G-CODE code, and how the notice printer is carried out.
The thermocouple schematic diagram as shown in Figure 4, other adjunct circuit can be finished according to the mode of connection of thermocouple, that Chip3 adopts is MAX6675, this chip is special-purpose cold junction compensation K type thermocouple conversion chip.For the 3D printer of colour, if in design, do not relate to the nozzle of supportive material, just have only a nozzle and spray booth, then only need a K type thermocouple to get final product.At first determine the maximum temperature of controll plant, select to be fit to the thermocouple of calibration number, the temperature range of K type thermocouple is-40~+ 1200 ℃.When needs supportive material, two or above spray booth and nozzle thereof then are set, need the K type thermocouple of respective amount this moment, controls the temperature of each spray booth respectively.Perhaps, can select the thermocouple of other types for use, various embodiments of the present invention all do not have extra restriction to this yet.
Power management as shown in Figure 5, Chip4 is KPJX-4S-S, it directly is connected with the 220V power supply, Chip5 is that LM1084-5V, Chip6 are V_REG_MIC2920; LM1084 and MIC2920 then are responsible for the voltage stabilizing of 5V power supply and 3.3V power supply.Chip most important control Stepping Motor Control, the Chip7 chip of Cai Yonging is the chip A4928 chip of Allergro here, its basic control interface is as shown in Figure 6.
Controllor for step-by-step motor has six needs and drives in colored 3D printer, also be that above-mentioned driving governor needs six, perhaps adopts the chip that can drive a plurality of stepper motors simultaneously also can.Wherein, Chip8 is MCP4018, and this is the digital regulation resistance of 7 single I2C.Other circuit mainly comprise peripheral components circuit such as SD card.
Software scenario: the control scheme of software refers to control colored printing flow process, flow chart comprises and subscribes color, the pulse of determining each stepper motor of tabling look-up, drives stepper motor, each stepper motor and drive consumptive material and enter spray booth, finally obtain required color as shown in Figure 7.Because the control of the system of 3D printer is not to control as other software systems, the value here all is that predefine is good.And the good color scheme of this predefine must be handled by replicatorG software in advance, and its concrete processing mode is the color scheme of introducing on original basis.Because the scheme of original replicatorG is to carry out the cutting of two dimension and the material of some supports of interpolation etc. by the model with the .stl form of three-dimensional.The scheme of this cutting in the time of the scheme of printing color, will increase new function, because must add this attribute of color.So when transforming, when the cutting threedimensional model, must introduce the color of model.When introducing color, the operation of its some Gcode is classified.Such as redness, then at this moment when mega2560 control step motor, can formulate the rotational angle of stepper motor SM1-SM3.Also be that some colors are with the number of degrees of the angle of corresponding six consumptive material drive motors.Just can realize printing to colour by this table.Also be the form that replicatorG has safeguarded a correspondence, the color scheme is mapped to the angle of stepper motor rotation among the Gcode or the pulse of each different stepper motor.The mapping table of color and motor pulses is as shown in the table.Such as the scheme of redness then its mapping scheme be " red ".
