Activated Alumina vs. Silica Gel
Slice Engineering offers an effective alternative to common desiccants like silica gel. Our Activated Alumina Desiccant, made of highly porous aluminum oxide, is a powerful moisture absorber. It outperforms silica gel, absorbing up to 20% of its weight in moisture, compared to 2-3% for silica gel. Our desiccant is non-toxic, ensuring safe usage for 3D printing applications. For additional information on safety and handling, the SDS (Safety Data Sheet) is available here.

Convenient and Efficient Design
We have designed our desiccant canisters to be compact and easy to use. They fit perfectly in the center of filament spools, enabling efficient moisture absorption even in tight spaces like the Bambu Lab AMS. When the desiccant becomes saturated, simply recharge it by baking the canister in the oven at 250°C (480°F) for two hours, preparing it for further moisture absorption.

Improve Print Quality
Often subtle, wet filament is a leading cause for many printing issues. Bed adhesion, stringing, and part finish are all majorly impacted by wet filament. With our Filament Drying Desiccant, you can enjoy moisture-free 3D printing, preventing issues like bubbling, stringing, and delamination.
