The quality of 3D prints is heavily influenced by the condition of the filament used. Moisture absorption can lead to significant printing defects such as bubbling, stringing, and delamination, diminishing the quality of the final product. Activated alumina desiccants offer a superior solution for maintaining filament dryness, ensuring optimal printing performance. As a leading supplier of high-performance desiccants, we understand the needs of the additive manufacturing community.

The Problem with Moist Filament

Many 3D printing filaments, especially hygroscopic materials like PETG, Nylon, and TPU, readily absorb moisture from the air. When these filaments are heated in the printer nozzle, the absorbed water turns to steam, causing internal voids, filament expansion, and uneven extrusion. This results in poor layer adhesion, surface imperfections, and weakened prints. Even filaments like PLA can absorb enough moisture over time to affect print quality.

Why Activated Alumina is Ideal for Filament Drying

Activated alumina, a highly porous form of aluminum oxide, excels at adsorbing moisture efficiently. Compared to traditional desiccants like silica gel, activated alumina generally offers a higher adsorption capacity, especially in moderate to high humidity conditions. Its key benefits for 3D printing filament storage include:

  • High Moisture Adsorption: Effectively removes and traps moisture, keeping filament dry for extended periods.
  • Durability and Reusability: Activated alumina is known for its robustness and can be regenerated by heating, allowing it to be reused multiple times, offering excellent value.
  • Non-Toxic Nature: It is generally considered non-toxic, making it safe for use in environments where handling is frequent.
  • Efficient Drying: Achieves low dew points, ensuring filament remains in optimal printing condition.
