Bambu Lab Molecular Sieve Desiccant replaces the legacy CaCl₂ powder desiccant for the AMS. It absorbs moisture physically rather than chemically, so it won't liquefy or leak, keeping your filament dry and your AMS clean. Regenerable by baking, it delivers longer service life and is cleaner and safer to handle.

Nothing will impact your 3D printing results like the kind of filament you use. Good filament is highly consistent in diameter, is wound evenly onto the spool with just the right amount of tension, and will not tangle when being unwound. 3D Universe offers a wide range of high-quality filaments to choose from.
