If you also experience these problems:
- air bubbles during filament extrusion
- deformed edge of printed objects
- formation of burrs (threads on the prints)
most likely the filaments you are using are wet, resulting in poor printing results!
An entry level solution is Filament Dry Box - filament dryer from Creality.
With this device you can keep your filaments safe from dust and moisture.
It is also compatible with most 1Kg filament spools on the market and with different filament diameters.
It features a front knob with disply to set a timer for automatic on/off.
After testing it we can recommend it for maintaining the temperature and humidity of the filament during printing, in fact it reaches about 40/45° C inside the box. In fact, these temperatures are not suitable for drying the moisture absorbed by some technical materials that require much higher temperatures to be restored to their original state.
