DESIGN AND IMPLEMENTATION OF TEMPERATURE AND SPEED CONTROL FOR EXTRUDER MACHINE TO RECYCLE SHREDDED 3D
PRINTED PRODUCTS MADE OF POLY (LACTIC ACID)

The purpose of this thesis is to make a temperature and speed control system that can run without any surveillance and determining the best possible temperature to run with this machine. This thesis was done by researching and experimenting on PID control on a dimmer module that has been programmed inside an Arduino. The PID control gets its feedback from a Thermocouple sensor with Max6675 module that communicates by translating the error from temperature into electricity power level for the dimmer module. The program can be launched multiple time without a need to reset the Arduino program. The first thing to do was turn on the heater and wait until the temperature gets to the setpoint which researched on this thesis. After that the relay that controls the motor will be turned on if temperature setpoint has been reached. the power level of induction motor that used in this thesis have been determined by research in this thesis, however, the power level still can be changed by the operator to change the speed of production without changing the quality of the produced filament.
