The FilaDryer S2 filament drying box is the ideal gadget to protect and store your filaments from moisture

360° surround heating

The FilaDryer heating speed is twice as fast as most drying boxes on the market and evenly dries your filaments with 360° drying.

Heating temperatures up to 70 °C

With a heating temperature of up to 70 °C, it is also possible to optimally dry more special filaments such as PA or PC.

Curved design & top to bottom drying

The clever curved design not only looks great – the feet give the device more stability and reduce heat transfer from the drying box to the ground.

The design with an upper and lower heating plate increases the heating efficiency by about 30%.

LED touch screen

The LED touchscreen allows you to view the temperature, time, material and LED settings simultaneously, so you always have an overview of the operation.

Intelligent drying modes for different materials

Smart presets for multiple filament types and drying modes make it easy to use and do not require manual settings.

You can also switch between displaying °C and °F.

    Really needs some form of air exchange fan. Other than that, will get the job done nicely. Prompt dispatch, excellent value.
    Support these guys.

    The product works fine in drying the filament. I dont advise using it as a filament feeder to the hotend using a Bowden system as the reel runs on rollers. with retraction settings longer than an all metal hotend caused my filament to snap due to the efficency of the rollers. The product is easy to use with presets for drying different filaments but you can adjust up or down.

    RH is not accurate I left my brand new tpu in the machine for 40 hours and it never dropped from 60% Rh
