I originally found SUNLU while looking for a good alternative to Bambu filament, mainly because Bambu was so often out of stock when I needed it. What started as a backup option quickly became my go-to filament thanks to the solid print quality, budget-friendly price, and the convenience of getting it fast through Amazon Prime. After using it regularly in my own setup, SUNLU has become the filament I trust most for everyday printing.

If your prints suddenly start looking rough, there’s a good chance the problem is not your printer at all, but your filament. In this post, I talk about why moisture is one of the biggest enemies of clean, consistent 3D prints and why vacuum sealing filament when it’s not in use has become my favorite simple way to keep it dry and ready to print.
