METHOD FOR AUTOMATIC CALIBRATION OF 3D PRINTER PLATFORM Russian patent published in 2023 - IPC B33Y30/00 G01B21/04 

FIELD: control; monitoring of a 3D printer.

SUBSTANCE: control and monitoring of a 3D printer, in particular calibration of a 3D printer platform. Method for calibration uses a calibration mechanism fixed to the stationary part, having an upper part with a microservo drive that moves the lower part of the calibration mechanism from a horizontal position to an upright vertical one. After the electrical circuit between the upper and lower parts of the calibration mechanism is closed, the mechanism is moved to the upper left corner, coordinates are determined, then it is moved to the right, and these operations continue until the lower right corner of the platform is reached. Then the accumulated data in the control unit is analysed, the required number of revolutions of the servo drives that control the spring mechanisms for adjusting the height of the platform is calculated. When the specified positioning accuracy is reached, the microservo drive moves the lower part of the calibration mechanism back to the horizontal position.

EFFECT: increase in the accuracy of calibration while maintaining the accuracy and quality of printing throughout the use of the printer.
