Technical Field
The invention relates to the field of 3D printing, which is different from the currently used 3D printing pen, is too thick and heavy. The user is not easy to operate, especially when the child uses the utility model. The invention relates to a superfine 3D printing pen device.
Background
The application of 3D printing is becoming more and more popular, where desktop 3D printers have walked into classrooms of primary and middle schools. Especially, in recent years, the 3D printing pen provides a simple creative tool for people, and the painting on the paper can be printed out by using the 3D printing pen to obtain an entity. However, the 3D printing pen is generally thick and heavy at present, and is inconvenient to use. The reason for this is that components such as a control circuit and a wire feeding motor are mounted on the 3D printing pen. One of the wire feeding motors is a micro motor (the diameter is less than 10 mm), but because the power of the motor is too small, the wire feeding thrust of the motor is small, and the extrusion of printing consumables is very difficult, the motor can only be installed at a place close to a pen point. This prevents the pen from being held. And the motor with high power is arranged at the upper part of the printing pen, the diameter of the position where the pen is held is reduced, but the weight of the whole pen is increased, and the head and feet are light, so that the over-control performance of the 3D printing pen is influenced. Next, the printer pen needs to heat the high-molecular printing consumable line to a molten state, and the thickness of the pen is determined by the heating device and the control circuit. Generally, the heating rate cannot be too slow, otherwise the use is affected. Therefore, a large-power heating device and control are required, and the size of the whole circuit board cannot be made too small due to the driving control of the motor. Therefore, by making all the above parts on one pen, the pen is not too thin and light. Such a pen can be handled by adults, but is particularly difficult for children. In addition, the printing consumables line that current 3D print pen used is generally a several meters long roll, and during the use, the printing consumables line is in free state, leads to in the use, and the consumptive material line twines together, influences the use. In addition, 3D print pen uses all to need the power consumption, and in the use, the print pen power cord will insert the 220V power, has an electric wire to drag the end at the print pen, and printing consumables line has two "tails" to drag, all can influence the user to the control of print pen. In most cases, users of 3D printing pens are teenagers and children, and using 220V power supplies, there is a potential risk to teenagers and children. For this reason, the 3D printing pen device of the present invention solves the above problems. The invention is to separate the 3D printing pen from other control parts. The 3D printing pen body becomes small and portable. The small and exquisite light printing pen and ordinary pencil, pen do not have nothing like this, and there is not discomfort when the ordinary user uses, the control of being convenient for moreover lets the user special writing in printing, just can print out more meticulous, exquisite three-dimensional model with the 3D printing pen. By using the superfine 3D printing pen, layer-by-layer printing can be quickly realized without long-term repeated practice, and a complex three-dimensional model is printed. In addition, the printer is small in size, convenient to carry, capable of being used without a power supply after being charged, and suitable for being used outdoors; the printing wire is stored in the printing cabin, cannot be wound during use, and is convenient to use.

In addition, the wire feeding control circuit and the temperature control circuit can be set according to the melting temperature of the printing wire, and the heating temperature can be increased or decreased through a knob. The wire feeding speed can be adjusted according to the habit of a user, and the wire feeding speed is accelerated or decelerated. The printing consumable cabin is internally provided with a wire feeding mechanism and a printing consumable line, and the wire feeding mechanism sends the printing consumable line to the 3D printing pen. The 3D printing pen is provided with a wire feeding pipe, and a resistance wire is wound outside the wire feeding pipe to heat the wire feeding pipe. The printing consumable line in the wire feeding pipe is heated to be in a molten state.
The core of the invention is the printing pen which heats the wire feeding pipe by using the control box, the printing consumable cabin and a resistance wire winding mode.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
The present invention provides a super-fine 3D printing pen device, and in order to make the objects, technical solutions, and effects of the present invention clearer and clearer, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The superfine 3D printing pen can be used after being charged, and can also be directly connected with a power supply for use. After charging, the solar cell can be used outdoors without a power supply. Charging source is the power supply of 3D print pen device, and the printing consumables line is sent into the silk pipe that send into in the 3D print pen through thread feeding mechanism and is intraductal. A commercially available 3D printing consumable wire PCL was used in this example, with a diameter of 1.75 mm and a melting temperature of 50 degrees. The wire feed tube was 2 mm. Adopt 0.2 millimeter resistance wire winding to heat printing consumptive material line on sending the silk pipe, 3D prints the diameter of pen and is less than 10 millimeters thick like this. When the PCL has low melting temperature, the temperature adjusting knob is rotated to the head in the minus direction. The user adjusts the wire feed speed knob according to the moving speed during printing. In the printing process, a user presses a wire feeding button on the 3D printing pen, and then the printing wire is extruded by the printing head to be printed. Releasing the button, the printing wire stops extruding. Because this 3D print pen is thin, light, uses super accuse nature good. In addition, only a limited length of printing line and wire is connected with the printing pen, and the winding of the printing line or the wire cannot be caused. The printing device is small in size, light in weight and convenient to carry, and can be used outdoors after being charged.
The superfine 3D printing pen device has the following advantages and characteristics:
1. the 3D printing pen is thin, light, simple in structure, convenient to operate, easy to learn and use;
2. the 3D printing pen device is small in size, can be carried about, does not need a power supply after being charged, and can be used and printed at any time;
3. the 3D printing pen device is used without power plug-in, and is safe to use;
4. the 3D printing consumable line is placed in the consumable cabin and cannot be wound.
