Does PLA Absorb Moisture? How to Prevent It?

If the PLA filament is stored in a humid environment, it can absorb moisture and become brittle. It is important to store PLA filament in a dry environment, such as a resealable bag with a desiccant, to prevent moisture absorption. If the PLA filament has already absorbed moisture, it can be dried out by heating it in an oven at low temperature. PLA filament that has been dried out will be less likely to break during printing.

What is PLA Filament?

PLA, or polylactic acid, is a 3D printing filament made from renewable resources like corn starch. PLA filaments are available in a wide range of colors and are biodegradable, making them a popular choice among eco-conscious consumers.

How long does it take for PLA to absorb moisture?

Depending on the level of humidity, it can take anywhere from 5 to 6 Days in a high humid climate or a week or more in a less humid climate for PLA filament to absorb moisture and become unusable.

Does PLA filament need to stay dry?

The short answer is yes, PLA filament does need to stay dry in order to maintain its strength and durability. If PLA filament gets wet, it can become brittle and break easily. In addition, moisture can cause the PLA filament to swell and distort, making it difficult to use in 3D printers. For these reasons, it’s important to keep PLA filament stored in a cool, dry place until you’re ready to use it.

How to prevent PLA Filament from Absorbing Moisture?

One of the most effective methods is to store the filament in an airtight container with a desiccant pack. A desiccant pack is a small pouch filled with a substance that absorb moisture, such as silica gel.

Another way to protect PLA filament from moisture is to keep it in a cool, dry place. It is also important to avoid exposing the filament to excessive heat or humidity. By taking these simple precautions, you can ensure that your PLA filament will remain in good condition for many prints to come.

How to remove moisture from PLA filament?

PLA filament can be tricky to dry out if it gets wet. Below are some of the ways to dry PLA filament.

  1. Using Food Dehydrator
  2. Filament Dryers
  3. Using Printer head bed

1. Food Dehydrator

The best way to dry PLA filament is to use a food dehydrator. Simply place the wet PLA filament on the dehydrator’s dehydrating racks, set the temperature to between 45-50 degree C, and let it run for 2-4 hours. You should check on the filament periodically to make sure that it is not overheating or drying out too quickly. Once the PLA filament is dry, it can be stored in an airtight container until you are ready to use it.

You can use Sunix Food Dehydrator for drying PLA filament. The Sunix Food Dehydrator Machine is designed specifically for that purpose! It can accommodate most common 3D printer filaments including PLA.

The machine itself is easy to use – simply load your PLA filament spool and select the desired drying time. The dehydrator will then work its magic, leaving you with perfectly dried filament that is ready to be used in your 3D printer.

Not only is the Sunix Food Dehydrator Machine convenient, it is also more cost-effective than buying pre-dried filament from the store. Buy Sunix Food Dehydrator today.

2. Filament Dryer

A 3D filament dryer is a device used to remove moisture from PLA filaments. Filament dryers are necessary because moisture can cause serious problems with 3D printed parts, including warping, delamination, and poor dimensional accuracy. There are several different types of filament dryers on the market, but they all work by circulating hot air around the filament in order to evaporate the moisture.

In most cases, filament dryers are used in conjunction with a desiccant, which helps to absorb any remaining moisture. By using a filament dryer, you can ensure that your 3D printed parts will have the best possible chance of success.

There are 2 kinds of Filament Dryers as below:

SUNLU Filament Dryer

The SUNLU filament dryer is one of the most popular models on the market. It features six heating elements that can reach a maximum temperature of 60°C (140°F). The SUNLU dryer also has a built-in desiccant chamber that helps to further reduce the moisture content of the filament. In addition, the dryer includes a number of safety features, such as an automatic shut-off when the door is opened, to prevent accidents.
