7 Essential Tips for Storing and Maintaining Your 3D Printing Materials

Imagine dedicating hours to preparing a complex 3D print, only to see it fail because of degraded filament. It’s a common frustration among 3D printing enthusiasts. The quality of your 3D printing filament plays a crucial role in the success of your projects, and understanding how to properly store and maintain these materials can make all the difference.

In this post, we’ll explore whether 3D filament can go bad and provide you with seven essential tips for storing and maintaining your 3D printing materials. By implementing these strategies, you can significantly improve your 3D printing workflow, reduce waste, and ensure consistent, high-quality prints.

Understanding 3D Filament Degradation

Before we dive into the tips, it’s important to understand what we mean by filament degradation. 3D printing filaments, like many materials, can deteriorate over time due to various environmental factors. The primary culprits behind filament degradation are:

• Moisture absorption
• UV exposure
• Temperature fluctuations

Moisture is arguably the most significant factor affecting filament quality. Many popular filaments, such as PLA and Nylon, are hygroscopic, meaning they readily absorb moisture from the air. This absorption can lead to changes in the filament’s physical properties, affecting its performance during printing.

UV exposure can cause filaments to become brittle or discolored, particularly for materials like ABS. Temperature fluctuations can impact the filament’s structural integrity, potentially leading to warping or other issues during printing.

According to a study by the Journal of 3D Printing and Additive Manufacturing, the average shelf life of properly stored PLA filament is about 2-3 years, while Nylon filament typically lasts 12-18 months. However, these figures can vary significantly based on storage conditions and environmental factors.

Signs Your Filament Has Gone Bad

Recognizing the signs of filament degradation is crucial for maintaining print quality and avoiding wasted time and materials. Here are some visual and performance indicators to watch out for:

Visual Indicators:

• Brittle or easily breakable filament
• Discoloration or a change in opacity
• Visible moisture bubbles or a “foamy” appearance when extruded

Performance Indicators:

• Poor layer adhesion or frequent print failures
• Inconsistent extrusion or frequent nozzle clogs
• Unusual odors during printing
• Increased stringing or blobbing

If you notice any of these signs, it’s likely time to take action to restore your filament or, in severe cases, replace it entirely.

Now, let’s explore the seven essential tips for storing and maintaining your 3D printing materials to prevent degradation and ensure optimal performance.

Tip #1: Proper Storage Conditions

Creating the optimal storage environment for your filament is essential for maintaining its quality over time. The two primary factors to consider are temperature and humidity.

Temperature Control:

Different filament types have varying ideal storage temperatures. As a general rule, most filaments should be stored between 10°C and 30°C (50°F to 86°F). However, some materials may have more specific requirements:

• PLA: 15°C to 25°C (59°F to 77°F)
• ABS: 10°C to 30°C (50°F to 86°F)
• PETG: 10°C to 30°C (50°F to 86°F)
• Nylon: 10°C to 25°C (50°F to 77°F)

Humidity Control:

Keeping your filaments dry is crucial for maintaining their quality. Aim for a relative humidity below 50% for most filaments, with some materials requiring even lower levels:

• PLA: <50% RH
• ABS: <50% RH
• PETG: <45% RH
• Nylon: <20% RH

To achieve these conditions, consider using desiccants like silica gel packets in your storage containers. These moisture-absorbing materials can help maintain a dry environment for your filaments.

Tip #2: Using Filament Storage Solutions

Investing in proper storage solutions can significantly extend the life of your filaments. Here are some options to consider:

Airtight Containers:

Airtight plastic containers or bins with sealable lids are an excellent option for storing multiple spools of filament. Look for containers with rubber gaskets or seals to ensure a truly airtight environment.

Vacuum Sealed Bags:

Vacuum sealing your filament spools can provide an extra layer of protection against moisture and contaminants. This method is particularly useful for long-term storage or for filaments that are especially sensitive to humidity.

Filament Dry Boxes:

Purpose-built dry boxes are designed specifically for 3D printing filaments. These often include built-in hygrometers to monitor humidity levels and may even feature heating elements to maintain optimal storage conditions.

Tip #3: Regular Maintenance and Inspection

Implementing a routine maintenance schedule for your filaments can help you catch potential issues early and extend the life of your materials.

Routine Checks:

Inspect your filaments at least once a month, or more frequently if you live in a particularly humid environment. Look for signs of degradation such as brittleness, discoloration, or moisture absorption.

Cleaning and Reconditioning:

If you notice signs of moisture absorption, you can often recondition your filament using a filament dryer or even a standard food dehydrator. For PLA, dry at 45°C to 50°C (113°F to 122°F) for 4-6 hours. For Nylon, use a higher temperature of 70°C to 80°C (158°F to 176°F) for 12-24 hours.

Case Study: John’s Filament Revival

John, a dedicated Filamatrix customer, observed a decline in print quality with his PLA filament after storing it in his garage for several months. By implementing a regular maintenance routine, including monthly inspections and occasional drying sessions, he reported a significant improvement in print quality and a reduction in filament waste.

“I was amazed at how much of a difference proper storage and maintenance made,” John shared. “Not only did I save money by reviving filament I thought was ruined, but my prints are now consistently better quality.”

Tip #4: Understanding Filament Shelf Life

Different filament materials have varying shelf lives, even under optimal storage conditions. Understanding these differences can help you manage your inventory more effectively.

Here’s a quick reference chart for the average shelf life of common filament types:

• PLA: 2-3 years
• ABS: 2-3 years
• PETG: 1-2 years
• Nylon: 12-18 months
• TPU/TPE: 1-2 years

Remember, these are general guidelines, and actual shelf life can vary based on storage conditions and environmental factors.

Tip #5: Troubleshooting Common Filament Issues

Even with proper storage and maintenance, you may occasionally encounter issues with your filaments. Here are some common problems and their solutions:

Stringing:

Cause: Excessive moisture in the filament or incorrect temperature settings.
Solution: Dry the filament and adjust retraction settings. For Filamatrix PLA, try increasing retraction distance to 6-8mm and speed to 40-60mm/s.

Warping:

Cause: Poor bed adhesion or uneven cooling.
Solution: Ensure proper bed leveling and consider using a brim or raft. For Filamatrix ABS, try increasing the bed temperature to 100-110°C and using an enclosure to maintain consistent ambient temperature.

Poor Layer Adhesion:

Cause: Insufficient extrusion temperature or contaminated filament.
Solution: Increase nozzle temperature in 5°C increments. For Filamatrix PETG, a temperature range of 230-250°C typically yields good results.

Tip #6: Optimizing Your 3D Printing Workflow

Incorporating proper filament care into your overall 3D printing workflow can lead to more consistent results and less wasted material.

• Store filaments in a cool, dry place when not in use.
• Use a filament cleaner or dust filter to remove particles before printing.
• Keep a log of filament usage, including date opened and any reconditioning performed.
• Print a test object after opening a new spool or reconditioning old filament to ensure quality.
• Consider using a filament runout sensor to prevent failed prints due to unexpected filament issues.

Tip #7: Choosing Quality Filaments

While proper storage and maintenance are crucial, starting with high-quality filaments can make a significant difference in your 3D printing experience. Filamatrix filaments are manufactured to strict quality standards and come vacuum-sealed with desiccant packets to ensure optimal condition upon arrival.

When selecting filaments, consider factors such as:

• Dimensional accuracy
• Consistency in color and material properties
• Spool design for easy storage and use
• Manufacturer’s reputation and customer support

Investing in quality filaments like those offered by Filamatrix can reduce the likelihood of print failures and improve overall print quality.
