Method for accurately controlling heating time of 3D printer

Abstract

The invention discloses a method for accurately controlling the heating time of a 3D printer. The implementation principle of the method is that a formula is calculated based on the theory of heat generation; according to the principle and processing method of the function approximation theory, the basic heating time and the following linear regression coefficients of the quadratic function approximation equation are precalculated; the heating elements and the heating voltage of the 3D printer are sampled and correspondingly standardized to calculate the required actual heating time; and finally, the heating time of the heating elements of the 3D printer is monitored through a microprocessor. A device is composed of a sampling module, the microprocessor, an interface module, a printer headpower supply control interface module, a power driving module and a data latching module. The device is used in the 3D printer; the optimal heating time can be accurately and quickly calculated according to the temperature of the heating elements and the heating voltage detected in real time, and the high-precision and large-capacity real-time control of the 3D printer with the inexpensive microprocessor can be realized.
