In general, a 3D printer includes these parts: mechanical part, circuit part, software part, and material part.
The mechanical part mainly includes the casing, XYZ three-axis system, stepper motor, printing nozzle, platform, etc.;
The circuit part mainly includes the power supply, motor drive, microcontroller, display, and button control , heating control, etc.;
The software part mainly includes chip software and host computer software;
The material part mainly includes common ABS PLA consumables;
Because 3D Printing is a mature equipment, so it is quite complicated overall. I can't explain it clearly in a sentence or two. The basic principle is that the host computer software imports the 3D model, sends the data after the model is cut to the chip, and the chip sends commands to control the nozzle. Heating, the movement of the XYZ three-axis motor and the movement of the feeding motor, the consumables are melted, extruded and accumulated to form a model.
As for the specific assembly, it is to install the motor, shaft and other mechanical accessories on the casing, connect the circuit board to the motor, display screen, power supply, etc., and install the software and it is ready to use. Antarctic Bear
