The quality of 3D prints often drops when cold and wet weather arrives. High humidity in the air, rain, snow, and storms eventually negatively affect your 3D printing materials. For example, some filaments absorb moisture, resulting in failed prints, and that’s when a good filament dryer comes in handy. Let’s unbox and review the new SUNLU filament dryer, Filadryer S2, to see how this small device can dry PLA, ABS, PETG, and other plastics and help you 3D print outstanding models.
