If you want to execute perfect 3D prints every single time, then your filament needs to be in good shape. Well, many types of filaments are hygroscopic, meaning they absorb moisture from the air. That means you can’t just leave them out, because they’ll likely cause weak and brittle prints, poor layer adhesion, nozzle jams, and an overall rough surface finish. Implementing the right storage tips to keep 3D printer filament dry is your best defense against moisture-induced issues. Here’s what you need to know!
Why Filament Must Stay Dry
We briefly touched on the issues that can happen when your filament absorbs moisture, but let’s dive in a bit more. When you heat moist filament in the printer’s nozzle, the trapped water turns to steam and creates bubbles within the molten plastic. This process results in inconsistent extrusion, which compromises the final print’s structural integrity and appearance.
Additionally, you might hear popping or crackling sounds during printing, which is a clear indicator that your filament has absorbed too much moisture. Keeping your filament dry preserves its optimal printing properties and extends its usable life, which saves you both time and money.
Best Storage Solutions
The best way to protect your filament is by storing it in an environment with controlled humidity. You can achieve this with a few different methods.
Airtight containers are an excellent first line of defense. You can use large, resealable plastic bags, plastic bins with gasket seals, or dedicated filament storage boxes. Moreover, placing desiccant packs, like silica gel, inside these containers will absorb any residual moisture. Some makers even use vacuum-sealed bags, which offer great protection by removing all the air.
Using a Filament Dryer
A filament dryer is another fantastic investment for any serious 3D printing enthusiast. This device actively heats and circulates air around the spool to remove moisture, restoring the material to its ideal state before you print. A filament dryer is particularly useful if you live in a humid climate or if you work with highly hygroscopic materials like Nylon, PETG, TPU, and PVA. Using a dryer just before printing is the most effective way to get flawless results.
Upgrade Your Printing Setup
Implementing these storage tips to keep your 3D printer filament dry is a simple step that makes a world of difference in the quality of your projects. By protecting your materials from moisture, you get stronger, cleaner, and more reliable prints.
