How long should PLA be dried for?

The recommended PLA filament drying temperature is 40-45°C at a time of 4-5 hours, which is right below this filament’s glass transition temperature, meaning the temperature at which it softens up to a certain level.

What temp should PLA be dried?

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.

How do I get humidity out of my filament?

Food Dehydrator – With the word “dehydrator” in it’s name, it does what it needs to, to remove any moisture from your filaments. The great thing about using a dehydrator is that all you have to do is set the temperature and leave your spool inside to dry.

Do filament dryers work?

These devices work by circulating air at very low heat for long periods of time to actively remove moisture. Food dehydrators make excellent filament dryers because they significantly reduce the humidity around the filament. If you don’t already have one, you can purchase one for around $50-$75.

Do you need to dry PLA before printing?

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.

Is filament dryer worth?

Ready-made filament dryers may be worth the price if you live in humid areas, 3D print often, and are willing to invest in it. These also have extra, useful features. However, some alternatives work just as well but may involve more effort or are inaccurate.

Can you Respool PLA filament?

Once you’ve reached the last section of filament on the old spool, cut it off (from the old spool). Pull the filament taut on the new spool to tighten it. Secure it down, so it doesn’t unravel. Leave your newly-wound spool to sit for a few hours, to allow the filament to bend into position.
