Avoid a Bad Filament Day!

Updated: Sep 18, 2021

Filament Storage

Proper storage of your filament ensures it will not get moisture will not leach into it, which can cause your print to string, bubble, filament to clog, and layer shifts and will lead to the filament needing to be dried out before you can use it.

There are multiple ways you can store your filament once it is opened.

Storage Bags

You can use vacuum storage bags, like the one below. Plain old zip locks work just as well! Add Desicannt to it to make sure the moisture stays out. The ones below are reusable.

Dryer Boxes

You can use these dryer boxes to store filament, but they are expensive if you keep a large inventory of open filament to use. If your printing environment is not ideal, then this is probably the best option for you. You can find adaptions for these boxes on thingiverse to feed filament directly from this box to your printer using PTFE tube. These are also an alternative to using your oven to dry out a filament that is already wet.

A cheaper option, which is always good, is to use Sterilite storage bins big enough for your filament. These have a gasket seal that prevents moisture and dust from getting to your filament. Combine this with desiccant if needed.

There are many amazing mods on thingiverse to turn this plan box into a unique functional storage system that you can use, even while the printer is using the filament!

Humidity Indicators

You'll want to keep track of the humidity level in your storage - be it in a sealed bag or in a storage bin. Here are a couple of great options.

Useful Filament Prints

There are several useful prints on thingiverse that may help improve your prints as well.

Dust filters keep your filament clean and wipe the dust off before entering your extruder, saving wear and tear and keeping your print jobs looking great.

These two prints are great for keeping the stress off of the filament before it feeds into the extruder. Using both will help keep the filament running smoothly, preventing snags and jams.
