How to Store 3D Printer Filament: Ultimate Guide for Longevity
How to Store 3D Printer Filament: Ultimate Guide for Longevity
The global 3D printing market is expected to reach $57.1 billion by 2028, underscoring the technology's rapid growth and adoption across industries. To maximize the value of your investment in 3D printing, it's crucial to understand how to store 3D printer filament properly.
Filaments exposed to moisture can produce poor-quality prints, causing issues such as stringing, clogs, and inconsistent layers. Knowing how to store 3D printer filaments correctly can avoid these problems and extend their lifespan.
Proper storage ensures your filament stays dry, maintains optimal performance, and reduces waste and print failures, helping you save on costs.
Why Proper Filament Storage Matters
Filament is made from materials that are highly susceptible to moisture absorption. When exposed to humidity, filaments can swell and trap water within. During extrusion, the trapped water becomes steam, causing bubbling, stringing, or brittle prints. This effect, known as foaming, compromises the print's structural integrity and finish. Different materials respond differently to moisture. For example:
PLA may become brittle.
Nylon becomes rubbery due to extreme moisture absorption.
PETG suffers from poor adhesion.
ABS loses its mechanical strength.
Storing your filament in controlled conditions prevents such issues, enabling smooth extrusion, strong layers, and predictable results.
Recognizing Moisture-Compromised Filament
When filament absorbs too much moisture, the signs are often noticeable:
1. Brittleness: Filament snaps easily instead of bending.
2. Surface Imperfections: Rough textures or uneven layers appear in prints.
3. Popping or Hissing Sounds: Steam pockets forming during extrusion cause these noises.
4. Color Shifts: Discoloration in the filament or the print.
If you notice these signs, drying your filament using a dryer or oven is a quick fix. However, proper storage can help you avoid these problems altogether.
Best Practices for Storing 3D Printer Filament
Knowing how to store 3D printer filament begins with addressing three key environmental factors that can degrade your material: humidity, heat, and
light. Follow these proven storage techniques to keep filaments in optimal condition.
1. Select the Right Environment
Store filament in a dry, cool, and dark space. For most materials, aim for humidity levels below 20% and temperatures between 50°F and 86°F (10°C to 30°C) to minimize degradation. Avoid direct sunlight, as UV rays weaken the filament.
Environmental Guidelines for Common Filaments:
2. Use Airtight Containers
Airtight containers are a cost-effective solution for filament storage. Options include sealed bins, vacuum-sealed bags, and resealable plastic bags. Add silica gel packs or other desiccants to absorb residual moisture. Replace desiccants periodically to ensure they stay effective.
Pros and Cons of Airtight Containers:
Pros: Affordable, simple to use, dust protection.
Cons: Limited space for large spools, frequent desiccant replacement.
3. Implement Filament Dry Boxes
Filament dry boxes are specialized solutions for maintaining low humidity levels. These units often come with humidity control and optional temperature regulation, ensuring ideal storage conditions. If a commercial dry box is outside your budget, a DIY approach using airtight containers equipped with desiccants can yield similar results.
Pros and Cons of Dry Boxes:
Pros: Precise humidity/temperature control, convenient for storing multiple spools.
Cons: Costlier than basic methods, requires regular maintenance.
4. Vacuum Sealing for Long-Term Storage
Vacuum sealing removes air, preventing moisture and oxygen exposure. To vacuum-seal filament:
1. Place the spool in a vacuum-sealed bag with desiccant packets.
2. Remove air using a vacuum pump or sealer.
3. Store the sealed bag in a cool, dark cabinet.
This method is ideal for infrequent users who need to store filament for extended periods.
Pros
and Cons
of Vacuum Sealing:
Pros: Compact, long-term protection.
Cons: Requires additional equipment, less accessible for immediate use.
5. Regular Monitoring
Routine checks help ensure your filament remains in good condition. Use a hygrometer to monitor the humidity inside your storage containers. If you notice any signs of degradation, dry the filament promptly with a filament dryer or oven at 104°F to 140°F (40°C to 60°C). Always follow the manufacturer’s guidelines to prevent overheating.
Tailored Storage Solutions for Different Filament
Types
Different filament types have unique storage needs. Here's how to store 3D printer filament based on its material:

Creative Storage Ideas
Custom Filament Storage Cabinet
A well-designed storage cabinet provides long-term filament protection:
Use airtight materials like metal or sealed plastic.
Install a dehumidifier or desiccant compartments to maintain 5%-15% humidity.
Incorporate adjustable spool holders for the organization.
Keep the cabinet in a temperature-controlled location.
DIY Dry Boxes
Combine airtight containers with desiccants and feed-through ports for a costeffective dry box. This setup allows simultaneous storage and direct filament feeding during prints, making it convenient and efficient.
Avoid These Common Filament Storage Mistakes
1. Exposing Filaments to Sunlight: UV rays weaken filaments. Always use opaque or UV-blocking containers.
2. Skipping Desiccants: Moisture exposure ruins filament. Always include silica gel packets or similar materials in your storage setup.
Prevents moisture-related print defects like stringing and bubbling.
How do I keep the filament dry?
Use airtight containers, desiccants, or a filament dryer.
Do I need to avoid sunlight?
Yes, UV exposure damages filaments over time.
Can I restore moisture-laden filament?
Yes, drying it in a filament dryer often restores its usability.
What’s the ideal humidity for filament storage
Aim for <20% humidity; specific needs vary by material.
Can I use everyday items for filament storage?
Absolutely! Vacuum-sealed bags and airtight bins work great.
By following these guidelines, you’ll master how to store 3D printer filament, ensuring optimal performance for every print while saving time and money. Whether you’re a beginner or an experienced maker, investing in proper filament storage pays off in the long run.
