During the process of fused deposition manufacturing, the extruding speed and the scanning speed of nozzle don’t match in some path of large change in direction may lead the extrusion of material more or less than demand too much which causes accumulation of material or the lack of line width. The method of controlling FDM’s forming accuracy which is under the restrictions of the mechanical structure of the work platform is studied. By adjusting the extruding speed and measuring the line width on the work platform the width of forming line in process can be controlled in allowed range. The experiment results indicate that through controlling the speed of extruding motor the extrusion of material is controlled efficiently and the accuracy of molding is improved.
