The best filament dryers for 3D printing

"If you own one of the best 3D printers, I'm willing to bet that you've come across wet filament issues at one point or another. No, this isn't a myth - nor is it a ploy to get you to purchase one of the best filament dryers, either. Wet filament is a very real issue with 3D printing that can significantly impact your print quality, and it all comes down to how much moisture your materials absorb."

"If you're fairly new to 3D printing and asking yourself if it's really a necessary investment to buy a filament dryer, let me save you the trouble of research and answer directly: yes. While you can get away with not having a dryer as you learn the craft and slowly get to grips with other 3D printing tools, over time, you'll notice errors like stringing, poor-quality surfaces, fragile models, rough edges, and even bubbles in your prints if your material becomes too damp."

"Some newer 3D printers, such as Bambu Lab's H series and the Anycubic Kobra S1 Combo, will have dryers built into the AMS units for added convenience, but not every printer will have this luxury. When printing materials like TPU, a filament dryer is an absolute essential. The box even states that you must dry out these filaments first before attempting to print with them. I've got all of the best filament dryers on the market rounded up for you below."

Filament absorbs moisture which degrades 3D print quality, causing stringing, poor surfaces, fragile models, rough edges, and bubbles. Drying filament restores consistent extrusion and reduces these defects. Some newer printers include built-in dryers in AMS units, but many machines lack integrated drying solutions. Flexible and hygroscopic materials like TPU require drying before printing to avoid failed prints. Beginners may temporarily manage without a dryer, but accumulated moisture will eventually reveal its impact on prints. Investing in a filament dryer preserves material properties and ensures more reliable, higher-quality results over time.
