How do I keep my 3D filament dry?

Filament is best kept dry in vacuum bags, a dry box

dry box

Dry boxes are used to safely store items that would otherwise be damaged or adversely affected by excessive humidity, such as cameras and lenses (to prevent fungal growth), 3D printing filament (to prevent moisture caused damages such as popping and sizzling when passing thru the hotend and turning into steam.

Dry box - Wikipedia

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.

Is it important to keep PLA filament dry?

PLA filament needs to be dry to ensure a smooth 3D printing process. Ideally, this would mean that your storage area is dry enough to not let enough humidity in for the PLA to absorb. With plastic bags, silica packs, and dry boxes, you can achieve this.

Do you need to dry 3D filament?

To remove excess moisture from material, it is necessary to place a filament spool in a suitable device to dry it. The time and temperature at which the heating operation should be carried out depends on the material used.

How do you protect PLA from humidity?

Some experts have suggested that PLA should be kept in an airproof box that can protect it from moisture especially if you are working in a humid environment. No matter if a filament is hygroscopic or non-hygroscopic, it is recommended to store them in a dry box to assure better quality and printing experience.

How do I lower the humidity in my filament?

Probably the easiest and most common way of drying filament is to use 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.

Do you really need to dry your filament?

Is it safe to dry filament in the oven?

Ovens are not recommended for drying filament, however it still can be done with caution. Convection ovens work very well as they constantly circulate hot air around the spool.

How long can I leave PLA out?

According to most users, even with 40% humidity, their PLA filament was alright for up to 4 days. The filament might become a bit brittle but overall it is not very risky to leave it out there.

Can you dry filament in the microwave?

A microwave oven is a common way of drying the filament at the appropriate temperatures. It eliminates any moisture that the filament could have absorbed. While other options like a desiccant or a dry box are risk-free, microwaves can cause adverse effects. But they are incredibly effective and do the job much faster.

Can you leave filament in extruder?

Most filaments you can leave in the extruder indefinitely without any ill effects. There are some filaments that need to be stored away from moisture, particularly Nylon, because they absorb moisture from the air and don't print well if they contain a lot of absorbed moisture.

How do you store PLA without using it?

To ensure your PLA and ABS filament remains dry, just return them to a sealed bag with dessiccant after use. The dessiccant will prevent/slow the material from absorbing moisture. Nylon and more sensitive materials should be stored in an actively dried container.

How should you store filaments?

Store your filament spools in transparent storage boxes with sealed lids. Use a cheap renewable dehumidifier to absorb any remaining moisture inside the boxes.

Can I microwave PLA?

It is compostable and can break down in certain composting conditions. It is also BPA-free with NO-toxic chemicals, microwave & dishwasher (top rack) safe, heat resistant up to 120 degree celcius.

What temperature does filament dry at?

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.

Does PLA filament absorb moisture?

PLA. PLA is an organic material that readily absorbs moisture, and is extremely sensitive to trace water content. Moisture also affects the diameter of the filament when it in storage.

What humidity should filament be stored at?

The ideal value of moisture in a filament is between 10-13 %.

Are Peltier dehumidifiers any good?

Theoretically, a Peltier module can last several decades. However, the Peltier modules used in these dehumidifiers are the cheapest most low quality modules on the market. They still may last for several years, but certainly not for the decades higher quality modules can last for.

Can moisture cause stringing?

Underextrusion, Stringing, Bubbles, and Oozing are all issues related to the presence of humidity in your filament.

Can you dry filament with desiccant?

To dry filament, you can use a specialized filament dryer by setting the required temperature and drying for about 4-6 hours. You can also use an oven or a vacuum bag with desiccant packs. A DIY airtight container also works well, and a food dehydrator is another great option.

What is a filament dry box?

What is a drybox? A drybox keeps the filament dry during printing and also protects the filament from dust. A 3D printer with our Multi-Material Upgrade not only allows you to print from filaments of different colors but also gives you the opportunity to print with different kinds of materials.

Is it safe to 3D print indoors?

New studies have confirmed that particles emitted from 3D printers can negatively impact indoor air quality and have the potential to harm respiratory health.
