When storing 3D printer filament, it is important to do this correctly. If you store the print filament incorrectly, this can cause it to become faulty. This is something you will want to avoid. For the majority of people that carry out 3D printing, storing the filament can be troublesome.
3D printer filament is temperamental. Given this you have to be careful when storing it. The most important thing to remember is that air should not be able to reach the filament. If it does, this will cause a whole host of problems because the moisture in the air will react to the filament.
The best way to store this filament is in vacuum bags. The vacuum bags will remove all the air and moisture. This means that the filament will remain protected and cannot be damaged by the air. It will help to preserve it when it is not in use, and you will not have to worry about checking on the filament again until you are ready to use it.
Vacuum bags are fairly inexpensive to purchase, and they will be able to hold around 3 to 4 filaments. To help with any excess water, you can place silica gel bags into the bag to catch any excess moisture too.
Alternatively, you can use storage boxes to store the filaments in. However, the boxes will need to be stored in a dark and cool place and are more likely to trap in air and moisture, which can affect the filament. If the box is well sealed, again you can use silica gel bags or a dehumidifier to help remove any moisture from the air.
The most important thing to consider is storing them in a place with as little moisture as possible.
