3D Printer, feeding mechanism, silicone


Additive Manufacturing as one of the methods used on a 3D Printer can be applied with silicone as its material by designing a feeding mechanism based on a syringe pump which considers its mass flow rate. The purpose of this experiment is to produce the design of a feeding mechanism and to know the correlation between stepper motor torque (Tsm) and CNC travel feed rate (VCNC) with mass flow rate. The geometry which will be reviewed is a line. Those parameters will be characterized by measuring the width of the line (x) on the desired nine measured points. The most stable mass flow rate on stepper motor torque is determined by the smallest difference between average line width, while the most stable mass flow rate on CNC travel feed rate is determined by the smallest deviation standard between each measured points. The characterization results show that the smallest stepper motor torque value has the smallest difference between the average line width, which is 1,92 mm; while the highest stepper motor torque value has the highest difference between average line width, which is 3,66 mm and the highest CNC travel feed rate has the smallest deviation standard, which is 0,91; while the smallest CNC travel feed rate has the highest deviation standard, which is 2,14. Both of the statements imply that a smaller amount of the stepper motor torque and a higher amount of CNC travel feed rate will induce a more stable mass flow rate, it also works the other way around.
