The Ultimate Filament Drying Guide
Because your 3D printer deserves dry noodles — not soggy spaghetti.
If your prints have ever looked like they were sneezed into existence… or your nozzle suddenly sounded like it was making Rice Krispies (snap, crackle, pop!)… congratulations:
🎉 You’ve met Moisture, the Arch-Nemesis of Filament.
Lucky for you, defeating this villain is easy — and Coex3D already does half the battle before the spool even reaches your doorstep.
Let’s get into it.
🌊 Why Does Filament Even Absorb Moisture?
Because polymers are drama queens.
Leave them out for a few hours, and they’ll start soaking up humidity like they’re on a spa retreat.
Wet filament can cause:
- Stringing that looks like your model grew spiderwebs
- Brittle filament
- Bubbles, pits, and surface zits
- Layer adhesion that says, “You’re on your own, buddy.”
So yes — drying matters.
🏭 How Coex3D Saves Your Prints (Before You Even Open the Box)
At Coex3D, we take moisture so seriously that it's practically a crime.
✔️ Spools are dried in our industrial oven after production
✔️ Immediately vacuum-sealed
✔️ Packed with fresh desiccant (which you can reuse — more on that below)
This means your filament ships out crispy, dry, and print-ready, unlike that spool on Amazon that sat in a sweaty warehouse for six months.
🔧 Recommended Drying Temps & Times
If your spool has been out in the wild (aka your basement), here’s how to give it a mini spa treatment:
| Material | Dry Temp | Dry Time |
|---|---|---|
| PLA / PLA Prime | 55°C (131°F) | 3–6 hours |
| PETG / PCTG Prime | 65°C (149°F) | 4–6 hours |
| ABS | 80°C (176°F) | 4–6 hours |
| ASA Prime | 80°C (176°F) | 4–6 hours |
| Nylon / PA | 80°C (176°F) | 8–12 hours |
| TPU / TPE | 50°C (122°F) | 4–6 hours |
| HIPS | 65°C (149°F) | 2–4 hours |
Important:
If you’re drying filament in a food dehydrator, oven, or filament-drier, always preheat first — overshooting temps can warp spools faster than you can say “Nooooo!”
♻️ Reusing Desiccant: The Secret Hack
Those little pouches that come with your filament?
Don’t throw them away — they’re tiny superheroes.
✔️ Spread them on a cookie sheet
✔️ Dry at 240°F (115°C) for 1–2 hours
✔️ Let cool
✔️ Put back into your filament container
Boom — good as new.
🏅 The Final Word
Dry filament =
✨ Smoother prints
✨ Stronger layers
✨ Happier nozzles
✨ Fewer surprise failures
And remember:
Every spool from Coex3D arrives pre-dried, vacuum-sealed, and ready for action.
Because your 3D printer deserves the good stuff.
