Ensuring the quality of your 3D prints starts long before you hit the print button. One crucial aspect often overlooked is 3d Printer Filament Storage. Many makers experience frustrating issues like stringing, brittle prints, or even failed prints, often caused by moisture absorbed by their filament. This article will delve into effective 3D printer filament storage solutions, specifically comparing dry boxes and filament dryers to help you maintain optimal filament condition.
Understanding Filament Moisture Absorption
3D printer filaments, especially hygroscopic materials like PLA, PETG, and Nylon, readily absorb moisture from the air. This absorbed moisture can significantly degrade print quality. When moist filament is heated in the hot end, the water turns to steam, leading to issues like bubbling, stringing, and weakened layer adhesion. Proper 3D printer filament storage is therefore not just about tidiness; it’s about preserving filament integrity and print quality.
Dry Boxes: Passive Protection for Filament
Dry boxes are a popular solution for 3D printer filament storage. These enclosures, often airtight containers, utilize desiccant materials like silica gel to absorb moisture from the air within the box. The primary function of a dry box is to maintain a low-humidity environment, protecting filament from further moisture absorption. They are excellent for storing filament long-term and preventing already dry filament from becoming damp.
However, dry boxes have limitations. Desiccant works passively; it can only absorb moisture that is off-gassed from the filament. If filament has already absorbed moisture deep within its layers, a dry box alone will struggle to remove it effectively. Think of it as maintaining a dry room, but not actively drying out damp clothes already inside.
Filament Dryers: Active Moisture Removal
Filament dryers offer a more active approach to 3D printer filament storage. These devices heat the filament to a controlled temperature, accelerating the evaporation of moisture trapped within the filament. By actively heating the filament, dryers can effectively remove moisture that has been absorbed, rejuvenating even noticeably damp filament. This process is crucial for restoring filament that has been exposed to humid environments or has been stored improperly for extended periods.
Combining Dryers and Dry Boxes: The Ideal Solution
For optimal 3D printer filament storage, a combination of both filament dryers and dry boxes provides the best results. Start by using a filament dryer to thoroughly dry any filament, especially if you suspect moisture absorption. Then, store the dried filament in a dry box to maintain its dryness over time. This two-step approach ensures your filament is not only dry before printing but also remains in optimal condition for future use.
Consider the experience shared in online 3D printing communities, echoing the findings of makers like CNC Kitchen. Even filament stored in a dry box for an extended period can still exhibit moisture-related printing issues, demonstrating the limitations of passive drying alone when dealing with already damp filament.
Finally, be mindful of filament spools themselves. Cardboard spools, sometimes used for materials like PETG, can also absorb moisture. While the filament is the primary concern, damp cardboard spools can contribute to the overall moisture level in your storage and potentially transfer moisture to the filament over time.
In conclusion, effective 3D printer filament storage is essential for consistent, high-quality 3D printing. While dry boxes excel at maintaining dryness, filament dryers are indispensable for actively removing absorbed moisture. For the best long-term filament health and printing success, utilizing both methods is highly recommended.
