Should PLA be kept dry?

PLA filament needs to be dried before use, as does all 3D printing filament. Of course, it’s best to keep the filament dry at all times, but if it gets wet somehow, you will need to dry or cure it before you can use it again. The reason is that moist PLA filament will swell and change in texture.

How does PLA need to be stored?

If you only print with PLA, store it in a low humidity environment and move through your stock rather quickly, keeping your rolls unwrapped is fine. But if your workshop is in a garage – or you work with more advanced filaments like TPU and nylon – moisture will become a problem.

How should I store my 3D filament?

Use double-zipped vacuum bags with a valve for sucking the air out with a standard vacuum cleaner. Place silica gel beads inside the bags to absorb any remaining moisture. Store your filament spools in transparent storage boxes with sealed lids.

Is drying PLA in oven safe?

Oven Drying – DIYers and professional 3D printers still utilize oven baking to get the moisture out of ABS and PLA filament. The drying process is similar to baking your favorite thanksgiving turkey. Just place your filament spool inside an oven and set it at the right temperature: 104 to 113°F (40 – 45 °C) for PLA.
