Creality Space Pi SE Filament Dryer vs SUNLU S2 Single-Spool Filament Dryer
Head-to-head spec comparison to help you pick the right environment upgrade for your needs.
Creality
$39.99
SUNLU
$44.99
One-spool dryer decision
Choose by heat ceiling and bench budget
Both are heated, print-through dryers for one active spool. Neither replaces a sealed dry box after the cycle ends.
Value pick
Space Pi SE
Pick the 65 C Creality when PLA, PETG, and occasional TPU are the main job and a lower-cost diagnostic dryer is enough.
Heat pick
S2 Filament Dryer
Pick the 70 C SUNLU when TPU, nylon, or stubborn wet PETG makes the extra heat and circulation worth the step up.

Pros & Cons
Creality Space Pi SE Filament Dryer
Pros
- Affordable entry point for users who need a real 65 C dryer before buying a full humidity-control setup.
- Compact enough for cramped desks, dorm benches, and one-printer workstations.
- Best fit for occasional PETG, PLA+, and TPU rescue cycles where multi-spool capacity is unnecessary.
- Pairs well with sealed storage boxes: dry one spool, store the rest.
Cons
- Weaker than newer 70 C Space Pi units and multi-spool stations for serious nylon or engineering-filament work.
- A lower-cost dryer still needs discipline: label materials, track cycles, and store dry rolls immediately.
- Limited station capacity means you will outgrow it if you print several materials every week.
SUNLU S2 Single-Spool Filament Dryer
Pros
- Single-spool format is the right size for diagnosing whether wet filament is actually the cause of stringing, popping, and dull surfaces.
- Active heat and a compact footprint make it easier to leave on the bench than a food-dehydrator workaround.
- Print-through path supports long PETG or TPU prints without moving the spool back into room air.
- Good middle ground for users who need real drying but do not yet need a four-spool station.
Cons
- One spool at a time becomes frustrating once you rotate several colors or materials every week.
- You still need dry storage boxes for partial rolls after the drying cycle.
- No single dryer can fix under-extrusion, retraction, or temperature mistakes that only look like moisture.
Our Verdicts
Creality Space Pi SE Filament Dryer
The Creality Space Pi SE is the value move for a bench that needs moisture diagnosis more than a permanent drying station. Buy it when you want to prove wet filament is the problem cheaply; step up to SUNLU S2, Space Pi Plus, or a multi-spool station when higher temperature, longer timers, or multiple rolls matter.
SUNLU S2 Single-Spool Filament Dryer
The SUNLU S2 is the most practical first filament dryer for a small Print Climate bench. It gives you a repeatable moisture-control step without forcing a huge workstation change, and it pairs naturally with sealed dry boxes once you have more than two active rolls.
