The Sprite extruder is compact and weighs about 260 grams.It also features a 3.5:1 gear ratio for improved accuracy and torque.But the best part is that the hot end is integrated in the extruder for better control of the filament.
The Sprite extruder on the Ender 3 S1 includes a small strip for connecting the heater box, thermistor, fan, and CR touch sensor.
The parts cooling fan is a single 4010 radial fan located at the front of the extruder and at an Angle to the nozzle to improve airflow.There is also a smaller radial fan on the left side of the extruder that blows air over the extruder’s radiator to keep the heat sink cool.It does a good job, especially considering the heat breaker is not bimetallic.
The Ender 3 S1 hot end is lined with PTFE, so do not expect to print at temperatures above 240C for long periods of time, as the tube will begin to degrade and produce harmful fumes.
