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.

How do I keep my filament moisture free?

Keeping filament in an airtight container is a must to prevent the absorption of humidity from the air, and the use of vacuum-sealed containers or ones with desiccant is even better.

Does PLA need to be kept dry?

Does PLA Need to 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.

Is a filament dryer necessary?

Filament dryers are essential tools for FDM 3D printing, as they enable you to recover wet filament. Spools of plastic used for printing can be degraded by moisture if left out in open air, yielding poor print quality and fragile parts. … This damages the plastic at a molecular level, making drying your filament a must.

How do you preserve a 3D printer filament?

To store filament correctly so that it doesn’t come into contact with moist air, you have three practical and relatively cheap options:
  1. Use double-zipped vacuum bags with a valve for sucking the air out with a standard vacuum cleaner. …
  2. Store your filament spools in transparent storage boxes with sealed lids.

How do you keep PLA dry?

The simplest way to dry any filament including PLA, is to simply chuck it in the oven and let it dry out. The longer you leave in the filament, the better the drying. For PLA, a maintained temperature between 104-113 °F (40-45 °C) is recommended.

How do you keep PLA filament dry?

Probably the easiest and most common way of drying filament is throwing it in the oven. Just set the temperature to right below the glass transition temperature of the plastic, and leave it in there for four to six hours for the moisture to evaporate. The longer you leave it, the drier it’ll get.

Can I dry filament in microwave?

The idea of drying filament in the microwave is not so appreciated. The reason behind it is that you not able to control the temperature properly which can lead to the melting of the filament inside the microwave. Drying your filament in a microwave is similar to boiling it, which wouldn’t be the best idea.

How do you make a filament dryer?

Top. Like so and now we have a filament dryer. And this thing costs me 40 bucks off Amazon. So you

Why does PLA filament get brittle?

The main reason for brittleness of filament is due to moisture absorption. ABS, PLA, and other common filament materials are mildly hygroscopic, so they will readily absorb moisture from the air. This is especially true if you live in a humid environment.

What temperature does filament dry at?

A spool of filament can be dried in a PrintDry filament dryer before 3D printing for storage. The dryer temperature can be set in a range of 35-70°C or 95-160°F. Relative humidity inside the PrintDry filament dryer can go as low as 10% after 2-hour drying.


How long does filament take to dry?

How long does it take to dry a filament? On average it will take around 5 h at 60 – 80 ℃ to dry a 1 kg filament spool, depending on the specific type of filament and the initial moisture content. Note that drying settings can vary largely even for nominally the same filaments coming from different manufacturers.

How long does it take for 3D printing to dry?

While heat drying 3D printer filament in an oven is overwhelmingly accepted within the 3D printing community, time is a major consideration. PLA and Nylon filaments may take upwards of 4 – 8 hours to dry between 150°F and 200°F.

How do you store unused PLA material?

Avoid storing unused PLA filament for extended periods (Greater than 12 months). Buy and use just enough to keep you going for the year. Store your PLA filament in an airtight container with some sort of desiccant. Airtight pet food containers are relatively cheap and large enough to hold a decent supply of PLA.

Does PLA filament have a shelf life?

While in an adverse environment, PLA is said to last between a few months to two years. While PLA is not water-soluble, it has a fairly high rate of water absorbency, or in technical terms, is hygroscopic. Exposure to moisture will lead to poor results when put into your 3D printer with the high-temp nozzle.

How much desiccant do you use for filament?

What we’ll be making is a simple, dehumidified environment for each roll to live in. One plastic bag and two silica packs per roll is all that’s needed to give the filament a very healthy, long life!
