3D Filament Dryers: Recommended Models

3D printing has revolutionized the way objects are created, however for the best results, it is important to use high quality filaments and make sure they are completely dry to get quality parts.

In this article I am going to introduce you to the different recommended 3D filament dryers so that you can choose the best one for your needs.

Why it is important to dry 3D filaments

3D printing filaments can absorb humidity from the environment and if they are printed with this humidity they can generate defects in the part such as cracks, bubbles, deformations and poor adhesion between layers... (See more consequences)

If the filaments are not dried properly it can affect the quality of the print.

For this reason, It is essential that you store your filaments in a dry place protected from moisture. Here you can see How to store 3D printing filaments.

And if they have already absorbed moisture, you will need a 3D filament dryer to remove it and leave them in optimal condition.

Recommended models of 3D filament dryers

If you are looking for a 3D filament dryer, there are several recommended models available on the market. Here are some recommended 3D filament dryer models:

Sunlu S1

Tips for drying 3D filaments

Regardless of the type of 3D filament dryer you choose, there are a few tips to follow to ensure your filaments are completely dry:

1. Store your filaments in a cool, dry place to prevent them from absorbing moisture.
2. If your filament is already wet, let it dry for at least 24 hours before using it.
3. Before printing, make sure your filament is completely dry. This will help avoid blemishes during printing.
4. Use a 3D filament dryer to ensure your filaments are completely dry before printing.
5. Remember that most dryers will have a fan to circulate the air and this can make some noise.
6. If you don't have access to a 3D filament dryer, you can use a conventional oven to dry the filaments. However, keep in mind that this can damage your filaments.

conclusions

3D filament dryers are an essential tool for any 3D printer, as they allow you to dry your filaments and avoid problems such as nozzle clogging, filament cracking and poor layer adhesion.

Hot air, vacuum, and silica gel dryers are the most common options on the market and offer different benefits and features.

It is important to choose the right model for your needs and make sure to store your filaments in vacuum bags or silica gel to protect them from moisture.

The choice must be made based on the type of filament used. If you only use PLA your best option (due to its value for money) it will be the Sunlu S1 dryer.

If you use other types of filaments such as ABS, PETG or even Nylon, your best option will be a dryer like the Sunlu S2 or the Esun Ebox since they have a greater temperature range and you will be able to dry the filaments in fewer hours.

Frequently asked questions (FAQs)

1. Why is it important to dry 3D filaments?

It is important to dry 3D filaments to avoid problems such as nozzle clogging, filament cracking and poor layer adhesion. The filaments can absorb moisture from the environment, which affects their quality and physical properties.

2. What type of filament dryer should I choose?

Choose a filament dryer to dry already wet filaments and vacuum bags with silica gel sachets to store them and prevent them from re-absorbing moisture.

3. Can I use a conventional oven to dry my filaments?

Yes, you can use a conventional oven to dry your filaments, but be aware that this can damage some types of filaments.

4. How do I know if my filaments are wet?

You can tell if your filaments are wet by looking for bubbles on the surface or if they make a crackling sound when printing.

5. How can I store my filaments correctly?

It is recommended to store the filaments in a cool and dry place, away from direct sunlight and moisture. You can use vacuum bags or silica gel to protect your filaments from moisture. (See here)
