And this is the result of our experiment. It can be seen that the values that give the highest hardness are layer height at 0.3 mm and speed at 70 mm/s and in terms of temperature, it can be seen that at temperatures 200 and 210 Degrees Celsius will not provide as much strength as a temperature of 220 degrees Celsius. This is because when printing, if the temperature is too low, it may cause the plastic filaments to break or become small.
