Musashi one-piece dispensing needle (3) Experimental methods and steps: Based on the traditional FDM molding process, this experiment studied the main factors affecting the quality of melt extrusion: pressure p, nozzle diameter d, platform moving speed v, etc. Wax is a soft material with low melting point, which is affected by uncertain factors in the nozzle, and the phase transition problem is involved in the melting process of casting wax. The extrusion of molten cat wax is a complex process, and the amount of extrusion cannot be accurately determined. This affects the uniform extrusion of the casting wax. In order to deposit molten wax accurately, the same mass of slurry extruded per unit time must be required. The experiment adopts the control variable method to ensure that the casting wax is uniformly extruded from the nozzle and accurately formed on the working platform. Experiment 1: Taking the driving air pressure p as the variable, if the air pressure is too low, the processing rate will decrease, and the nozzle will be easily blocked; if the air pressure is too high, the deposition line width (w) will be too large, which will affect the accuracy of the parts. The pressure should not be too low or too high, and a reasonable pressure range should be selected. Adjust the pressure controller to change the pressure (p) in the barrel, and study the influence of the pressure (p) on the line width (w) of the casting wax. As the air pressure continues to increase, so does the line width. The air pressure determines the extrusion speed; if the extrusion air pressure is too low, the processing speed is reduced, and the nozzle is easily blocked; The pressure should not be too low or too high, and a reasonable pressure range should be selected. Adjust the pressure controller to change the pressure (p) in the barrel, and study the influence of the pressure (p) on the line width (w) of the casting wax. As the air pressure continues to increase, so does the line width. The air pressure determines the extrusion speed; if the extrusion air pressure is too low, the processing speed is reduced, and the nozzle is easily blocked; The pressure should not be too low or too high, and a reasonable pressure range should be selected.
