Problems solved by technology

At present, the functions of the 3D printer control system are mostly concentrated on the motion control of the printer extrusion head. The printer heating control module mostly adopts the constant temperature control mode in combination with the materials. The printing quality has a direct impact, but most of the existing control systems are open-loop systems. Because there is no feedback during control, the accuracy is generally difficult to meet the requirements. In addition, most of the existing printers need to be used with a computer, and the computer is used as the carrier of the control system. , increasing the complexity of the overall structure of the printer machine control system
