基于FDM 3D打印机机械结构和控制系统设计的研究OA

The 3D printer design strategy supported by FDM technology is studied.Using the core coordinate control system of step control precision of 0.002 mm lead screw slider + step motor,one set of lead screw is used to control the positioning of x-axis and y-axis respectively,two sets of lead screw are used to control the positioning of z-axis,three sets of FDM extrusion system are used to control the color printing process,after discussing the algorithm of setting control and cooling forming,a kind of LED with seven actuators mechanical structure and control system of 3D printer with integrated status display function is designed.And the system can directly transfer files from the desktop to the ARM system of the 3D printer through a USB cable.Based on the research on the mechanical structure and control system design of FDM 3D printers,it can be concluded that by innovating coordinate control algorithms and cooling forming algorithms,improving control strategies for stepper motors,increasing the types of 3D model files recognized by driver programs,and further optimizing and controlling the forming process of FDM materials,it is a key development direction for 3D printers supported by FDM technology in the future.
