Structure for precisely controlling heating time of 3D printer

Abstract

The invention discloses a structure for precisely controlling the heating time of a 3D printer. According to the working principle of the structure, firstly, according to a theoretical calculation formula of heat generation, the base heating time and all linear regression coefficients of the following quadratic function approximation equation are pre-obtained according to the principle and treatment method of the function approximation theory; then heating elements and the heating voltage of the 3D printer are sampled and correspondingly standardized to calculate the actually needed heating time; and finally the heating time of the heating elements of the 3D printer is monitored through a microprocessor. The structure is composed of a sampling module, a microprocessor and interface module,a printer head power supply control interface module, a power drive module and a data latching module. The structure is used for the 3D printer, the optimum heating time can be accurately and quicklycalculated according to the heating element temperature and heating voltage which are detected in real time, and then the 3D printer can be subjected to high-precision and large-capacity real-time control through the cheap microprocessor.
