Storing 3D printing filaments is key to maintaining their quality and avoiding problems during the printing process.
The best way to store 3D printing filaments is to store them in airtight containers with moisture absorbers in a cool, dry place away from dust and moisture.
These containers can be hermetic bags or boxes that prevent the entry of outside air, thus preventing their deterioration.
Why is it important to store filaments?
The filament is a key component in the 3D printing process, and any damage or degradation in its quality can negatively affect the final result.
In this publication I show you what are the consequences of moisture on printing filaments with photos and examples.
3D printing filaments are sensitive to humidity, heat, direct sunlight, and other environmental factors, which means they must be stored properly to maintain their quality and avoid printing problems.
What to consider when storing 3D printing filaments
Temperature, humidity, direct sunlight, and dust can affect the quality of print filaments. Therefore, you should consider all these factors before choosing the way and place to store them.
Temperature is a key factor when storing 3D printing filaments. Most 3D printing filaments should be stored at cool, dry temperatures, preferably somewhere between 15 and 25 degrees Celsius..
PLA filaments can be stored at slightly higher temperatures, between 20 and 30 degrees Celsius, while Nylon and ABS filaments should be stored at lower temperatures, between 10 and 20 degrees Celsius.
Humidity is another important factor when storing 3D printing filaments.
Moisture in the filament can cause problems during the printing process, such as bubbles, streaks, and other blemishes.
To avoid humidity, it is important to store the filaments in a dry environment.
You can store them in an airtight bag with a desiccant packet to absorb moisture.
Direct sunlight can degrade 3D printing filaments, especially those that are sensitive to UV light. It is important to keep the filaments away from direct sunlight and store them in a dry place, out of direct sunlight.
Dust can stick to 3D printing filaments and affect the quality of the resulting prints. It is important to store the filaments in a clean and dust-free place.
In case your filament has already collected dust you can download and print a filament cleaner from Thingiverse, link here.
How to store 3D printing filaments
Now that you know what to consider when storing 3D printing filaments, here are some tips on how to do it correctly:
Use an airtight bag
One of the most common and cheapest ways to protect your filaments is to store them in an airtight bag, with moisture absorbers.
An airtight bag is a great way to keep your 3D printing filaments dry and free of dust. You can use the original bag or if you have already thrown it away, buy new bags.
You can buy special hermetic bags for 3D printing filaments or just use a vacuum storage bag.
Be sure to include a desiccant packet in the bag to absorb moisture.
On Amazon you will find two types of bags for vacuum sealing, a model with a manual vacuum pump and another model with a USB vacuum pump.
I leave you the links of both products here below.
- Complete Vacuum Storage Kit: Size is 30 x 40 cm. In general, you can store 1 kg of filament…
- Keep your filament dry: with the 3D printer filament storage kit you can protect your filament…
Use an airtight container or “Dry Box”
An airtight container with moisture absorbers It is another option to store your 3D printing filaments. Make sure the container is clean and dry before placing the filaments inside.
The biggest benefit is that you will be able to store (and protect) several rolls of filament at the same time.
You should make sure that the container has a tight lid to prevent moisture or dust from entering.
In 3d printing we know them as "Dry Boxes" (or "DryBox" in English) and their function is to keep the 3D filaments dry, free of moisture.
You can look for ideas in thingiverse on how to place a roll holder inside these containers.
By printing some supports and accessories you can keep your filaments safe from moisture, while you can easily use them without having to remove them.
Print some Filament Holders
Print a hermetic Filament Holder, ready to dispense filament while you print.
With a filament holder you can keep your roll protected at the same time that you use it, this can help you since you will not have to take it out and put it back every time.
Store the filaments in a dry and cool place
To prevent degradation of 3D printing filaments, it is important to store them in a cool, dry place, out of direct sunlight.
You can store them in a closet or on a shelf in a place that is not exposed to direct sunlight.
Do not expose them to moisture
Moisture can damage 3D printing filaments, so it's important to avoid exposure to moisture. If you live in a very humid environment, you may consider using a dehumidifier in the storage area to reduce the humidity in the air.
Do not store them for a long time
Even if you store your 3D printing filaments correctly, you should not store them for too long periods of time. Ideally, use them within six months to a year. If you need to store them for longer, be sure to check their quality before printing on them.
Storing your 3D printing filaments correctly is key to maintaining their quality and avoiding problems during the printing process. By following these tips you can ensure that your filaments stay in good condition and you can get high-quality prints.
