3D printer

Abstract

A 3D printer comprises a driving wheel which is arranged in the moving direction of a printing wire produced by the 3D printer and is used for driving the printing wire, and a motor used for driving the driving wheel. The 3D printer further comprises a wire plugging detection module. The wire plugging detection module comprises a driven wheel which is subjected to the friction of the printing wire to rotate, a reflective photoelectric switch which is used for detecting whether the driven wheel rotates or not, and a single chip microcomputer which is electrically connected with the reflective photoelectric switch and the motor. The reflective photoelectric switch emits pulse signals when detecting that the driven wheel rotates, and does not emit pulse signals when detecting that the driven wheel does not rotate. The single chip microcomputer is standby when receiving the pulse signals, and emits control signals to enable the motor to stop working when not receiving the pulse signals. According to the 3D printer, when the printing wire is plugged, the motor can be actively made to stop working, and therefore raw material waste caused by continuous printing wire conveying is avoided.

Description

technical field [0001] The invention relates to a printer device, in particular to a 3D printer. Background technique [0002] With the development of printer technology, 3D printers capable of printing three-dimensional objects are gradually emerging. Traditional inkjet printers spray ink onto paper and other carriers to display a two-dimensional image. The 3D printer does not rely on ink to display, but relies on real raw materials such as plastics and metals, and softens the raw materials into printing filaments by heating to spray them on the preset area. After receiving a series of digital slices completed by a computer, a 3D printer stacks successive thin layers until a three-dimensional solid object is formed. It can be seen that 3D printers can directly print shaped products, thus providing a new manufacturing method. [0003] Existing 3D printers often take a long time when printing a product, especially in the process of printing large and complex products. Whe...

[0003] Existing 3D printers often take a long time to print a product, especially in the process of printing large and complex products

When the 3D printer is running for a long time, the printing wire produced by the 3D printer is prone to clogging

Once the printing wire is blocked, if the 3D printer continues to work and the printing wire is conveyed, the printing wire will not be effectively used, resulting in waste of raw materials and increased production costs.
