Hey everyone – Josh here, aka The IRON3Dad. Many of you know me for my ridiculously thorough input and occasional dad jokes… Well - I just finished beta testing the Creality SpacePi X4 filament dryer.
** Me chuckling mischievously in eloquent creative writing narration 
Spoiler alert it seriously impressed me!
I ran full tests across:
- Hydro-loaded filament (in a homemade Chaos Chamber)
- Wattage + decibel readings under load
- Timed temp metrics
- Moisture recovery tests on PLA, PETG, TPU, ASA, and PPA-CF
- Before/after print comparisons for each filament

This thing handled everything I threw at it — and then some… I even ran a 32-hour PPA-CF dry to see how it held up over long durations (spoiler: it did great).
Big thanks to @Creality and @Optimus for letting me be part of this beta. If anyone has questions about temps, test results, or settings — I’m happy to share more.
Let me know what you think — and if you’ve tested the X4 yet, I’d love to hear your results too!
