A filament dryer is a device used to remove moisture from filament, which is a thin strand of material used in 3D printing. Moisture can cause filament to become brittle and break during printing, so it is important to use a filament dryer to ensure that your prints are of high quality.
There are many different types of filament dryers on the market, so it is important to choose one that is right for your needs. Some dryers are designed to dry filament quickly, while others are designed to dry filament more gently. It is also important to consider the size of the dryer and the amount of filament that you need to dry.
