and step A2, when the printing instruction is received, reading a printing file corresponding to the printing model in a file system, and printing the printing model based on the printing file.

In the present embodiment, the printing process of the print control module: a main control chip of the 3D printer receives a printing instruction corresponding to the printing model; when a printing instruction is received, program codes corresponding to a printing model in a file system are analyzed, the multi-path stepping motor is controlled to work independently through the multi-path stepping motor driving unit, and the stepping motor drives the moving support to complete corresponding actions through the transmission device, so that the printing of the model can be completed.

Step S20, according to the printing area and the control area, determining a target control area needing to be heated in the control area;

in the present embodiment, after acquiring the current printing area of the print model, the printing area and the control area are compared to determine the target control area to be heated in each control area on each printing platform board. That is to say, the 3D printer automatically identifies the printing area to be printed, so that the 3D printer determines the target control area which needs to be heated currently on the printing platform board according to the current printing area, and the area which needs to be heated on the printing platform board can be controlled to be printed according to the printing area which needs to be printed each time.

Further, referring to the schematic diagram of the control area of the printing platform board shown in fig. 6, the control area includes a heating inner ring, a heating middle ring and a heating outer ring, and the heating middle ring is located between the heating inner ring and the heating outer ring; the control areas correspond to the heating control units, and each control area is provided with a temperature detection sensor.

In this embodiment, a printing platform board of a 3D printer is provided with a plurality of independent control regions, each control region is a heating region for heating a 3D printing material on the printing platform board of the 3D printer, each control region is composed of a heating inner ring, a heating middle ring and a heating outer ring, the heating middle ring is located between the heating inner ring and the heating outer ring, the diameter of the heating inner ring is smaller than that of the heating middle ring, and the remaining control regions except the heating inner ring and the heating middle ring on the control regions are heating outer rings; the shape of the control region may be a square, a rectangle, a circle, or the like, and the shape of the control region is not particularly limited in this embodiment. Each control area is controlled by a heating control unit, namely the heating of the heating inner ring is controlled by the inner ring heating control unit corresponding to the heating inner ring, the heating of the heating middle ring is controlled by the middle ring heating control unit corresponding to the heating middle ring, and the heating of the heating outer ring is controlled by the outer ring heating control unit corresponding to the heating outer ring. When any one of the control areas needs to be heated, the corresponding heating control unit is controlled to heat.

Referring to the schematic diagram of the control area of the printing platform board shown in fig. 6, in an embodiment, the heating inner ring at the center of the printing platform board may be a circle with a diameter of 120mm, and the heating inner ring is uniformly arranged in the area for heating, and a temperature detection sensor is installed on the inner ring area for detecting the real-time temperature of the inner ring. The middle part is a heating middle ring with the diameter of 200mm, and a temperature detection sensor is arranged on the middle ring and is used for detecting the real-time temperature of the middle ring. The outermost part is an outer ring area corresponding to the heating outer ring, and an independent temperature detection sensor is also placed. The power of each heating circular ring is 100W, the interval is 2mm, and the heating circular rings are connected only by 4 small supporting points to avoid temperature conduction among the rings. The upper part of the printing platform board is provided with an independent area for placing the MCU processor and the heating control element.

According to the law of resistance(where ρ is the resistivity of the heater and S is the cross-sectional area of the heater), it can be seen that the resistance R of the heater is proportional to the wiring length L. According to ohm's law(wherein U is the heating voltage of the position power supply, and R is the total resistance of the heating wire). Therefore, the corresponding heating power can be obtained by adjusting the wiring length of the heating wire.

For example, when a model with a diameter of 100mm is printed in the center, the MCU processor only starts inner ring heating and closes the middle ring and outer ring heating, and the heating power is only 100W, so that 66% of electric energy can be saved. When a model with the diameter of 150mm is printed, the MCU processor starts the inner ring heating area and the middle ring heating area, the heating power is 200W, and 33% of electric energy can be saved. When printing a model with a diameter of 200mm, all heating zones are switched on simultaneously, with a maximum heating power of 300W.

And step S30, heating the target control area by the heating control unit corresponding to the target control area.

In this embodiment, after automatically identifying a target control area to be printed, the 3D printer determines a heating control unit corresponding to the target control area according to the target control area, and heats the target control area through the heating control unit corresponding to the target control area, so that when the printing area is printed, the heating control unit corresponding to the target control area heats the target control area. If the target control area comprises a plurality of control areas, the determined heating control units also comprise a plurality of control areas, because the control areas correspond to the heating control units one by one, and one heating control unit correspondingly controls one control area.

In this embodiment, the printing platform board of the 3D printer is provided with a plurality of independent control areas, each control area includes a heating inner ring, a heating middle ring and a heating outer ring, and each control area is independent and is controlled by an independent heating control unit. Each control area is controlled by a heating control unit, namely the heating of the heating inner ring is controlled by the inner ring heating control unit corresponding to the heating inner ring, the heating of the heating middle ring is controlled by the middle ring heating control unit corresponding to the heating middle ring, and the heating of the heating outer ring is controlled by the outer ring heating control unit corresponding to the heating outer ring. When any one of the control areas needs to be heated, the corresponding heating control unit is controlled to heat.

The process of determining the target control area needing to be heated in the control area according to the printing coordinate range corresponding to the printing area specifically comprises the following steps: if the printing coordinate range falls within the range of the heating inner ring, the target control area needing to be heated in the control area is the heating inner ring, and the heating inner ring is heated when the model is printed. If the printing coordinate range falls within the range of the heating middle ring, the target control regions needing to be heated in the control regions are the heating inner ring and the heating middle ring, and the heating inner ring and the heating middle ring are heated when the model is printed. If the printing coordinate range falls within the range of the heating outer ring, the target control areas needing to be heated in the control areas are the heating inner ring, the heating middle ring and the heating outer ring, and the heating inner ring, the heating middle ring and the heating outer ring need to be heated simultaneously when the model is printed.
