Why do 3D printers need fans?

A part-cooling fan is responsible for cooling freshly-extruded plastic as soon as it exits the nozzle. This eliminates warping and various other print problems.

Do you need to ventilate a 3D printer?

All 3D printers should be ventilated to avoid inhaling toxic materials. Ventilation prevents safety disasters and health issues that can occur in the long run. Always purchase the right 3D printer and use eco-friendly materials to avoid fatal disasters.

Can you run 3D printer without extruder fan?

No. In most cases, the motors will never reach temperatures for which a fan is required. This is because most stepper motors are rated for safe operation at temperatures up to 100 °C.

What does extruder fan do?

An extruder is simply the machine used to complete the extrusion process. Using a system of barrels and cylinders, the machine heats up the product and propels it through the die to create the desired shape.

What is initial fan speed?

Initial fan speed – This controls the fan speed on the initial layer only, which adheres to the build plate. The speed then changes back to the regular fan speed, which is achieved once it reaches the height setting for the regular fan speed.
