Creatbot F series part cooling fan

Description The part cooling fan plays an important role in printing materials like PLA, PETg & TPU. For PLA, full fan speed is recommended. For petg & TPU, around 30-50% is enough. Do not use fast fan speeds on materials other than PLA as it risks your over cooling the layers, which cases parts to crack due to poor interlayer adhesion. Sometimes 30% fan speeds are used with Carbon fiber reinforced nylon filaments, but this can increase stringing & should be done carefully. Don’t use fans with ABS, Polycarbonate, Nylon, PEEK etc – unless the machine has an active heated chamber & you have a specific reason to use the fan with such materials.
