Does PLA need to be vacuum sealed?

PLA is hygroscopic, meaning that it will absorb water from the air over time. For printers that buy PLA in bulk, this can present a storage problem. It is always a good idea to store PLA in an airtight box with a desiccant (a chemical that dries out the air) or used a vacuum seal bag.

Why is PLA filament vacuum sealed?

Do I need to store PLA in a dry box?

Though it is not totally necessary to store PLA filament in a dry box, leaving open spools of filament out to deal with ambient conditions on their own, will always be a bad idea.

Which filaments should be kept dry?

It is a good idea to keep your PLA filament as dry as possible to get the best 3D printing experience. Not just PLA, but every filament that absorbs moisture should be kept dry because moisture can cause plenty of problems. It can cause the filament to break down while extruding from the nozzle.

How do I keep my 3D printer filament dry?

Filament is best kept dry in vacuum bags, a dry box or cabinet or a specialized 3D filament box. You can put it in a food dehydrator or an oven to dry it. A moisture-free environment is ideal for keeping your filament dry. Using desiccants in an enclosed area is the best method.

What is a filament dryer box?

A filament dry box is a storage solution that encloses your filament in a moisture-free environment to prevent the spool from absorbing water from the air.
