[0002] The working principle of FDM 3D printer is to heat the hot-melt material (such as PLA, ABS, etc.) to a molten state, and then extrude the molten filament through an extruder with a micro nozzle, depositing layer by layer on the workbench, and finally building a three-dimensional object. This process is automatically controlled by a computer, the nozzle moves in the X-Y plane, and the workbench moves in the Z direction to realize three-dimensional modeling. During the use of FDM 3D printer, it needs to cooperate with the printing plate detection device.
[0003] However, the printing plate detection device for FDM 3D printer on the market is not very convenient to use, and cannot detect the height of the printing plate during the use of the FDM 3D printer, so the staff needs to manually adjust the height of the printing plate, which increases the work content of the staff, improves the work complexity of the staff, reduces the printing efficiency of the printer, and is not conducive to the long-term use of the DFM 3D printer.

[0006] The outer wall of the detection device fastening screw is movably connected with a detection device fixing seat, the bottom of the detection device fixing seat is fixedly connected with a detection device conducting block, and the bottom of the detection device conducting block is movably connected with a thin film pressure sensor. The staff does not need to manually adjust the height of the printing plate, which reduces the work content of the staff, reduces the work complexity of the staff, improves the overall printing efficiency of the printer, and is conducive to the long-term use of the DFM printer.
[0007] Further, the bottom of the thin film pressure sensor is movably connected with a thin film pressure sensor fastening screw, and the number of thin film pressure sensor fastening screws is two, which provides fixation for the thin film pressure sensor.
[0008] Furthermore, the outer wall of the fastening screw of the thin-film pressure sensor is movably connected to an elastic pad, and the elastic pad has a cylindrical hollow structure to provide cushioning for the operation of the device.
[0009] Furthermore, the bottom of the heating plate is fixedly connected to a lower plate, and there are two lower plates, which ensures the stable operation of the device.
[0010] Furthermore, the bottom of the lower plate is fixedly connected with a spring, and each lower plate has a spring at its bottom, which provides support for the height of the printing plate and facilitates the downward pressing of the printing plate.
[0011] Furthermore, a lower column is fixedly connected to the bottom of the lower plate, and the lower column passes through the center of the spring, so that the detection device can be positioned relative to the printer.
[0012] Furthermore, the bottom of the soft magnetic plate is fixedly connected to the top of the heating plate, and the length and width of the soft magnetic plate are equal to the length and width of the heating plate, providing stability for printing the item.
[0013] Furthermore, the outer wall of the fastening screw of the detection device passes through the heating plate and is movably connected to the top of the detection device mounting base, and there are two fastening screws for the detection device mounting base.
[0014] Furthermore, the specific steps include: S1. After the printing plate is installed, the heating plate starts to work, which raises the temperature of the printing plate.

This device consists of a print plate, a soft magnetic plate, a heating plate, detection device fastening screws, a detection device mounting base, a detection device transmission block, an elastic pad, a thin-film pressure sensor, and thin-film pressure sensor fastening screws. After the print plate is installed and printing is desired, the transmission block activates. Through laser transmission at the bottom, the transmission block obtains the height of the print plate, soft magnetic plate, and heating plate. The FDM 3D printer can then adjust the print plate height during printing to complete the 3D printing of the object. This eliminates the need for manual adjustment of the print plate height, reducing the workload and complexity for operators, improving the overall printing efficiency of the printer, and contributing to the long-term use of the FDM 3D printer.
[0016] 2. The FDM 3D printer uses a printing plate detection device, which, through the setting of a lower plate, spring and lower column, allows the printing plate to spring back to its initial position when no pressure is applied, thus facilitating subsequent work and making it easier to raise the height of the printing plate while the FDM 3D printer is working, thereby completing the 3D printing of the object.
