The Creality Space Pi Plus Filament Dryer reigns supreme with its wider temperature range, advanced PTC heating, and extended timer, making it ideal for serious 3D printers handling ABS, Nylon, or large decor projects—well worth the higher price. For budget-friendly PLA and PETG drying, the Comgrow Filament Dryer Box is a solid contender, perfect for beginners.
I’m midway through printing a sleek vase for my living room, and suddenly, my filament starts stringing like crazy. The layers look messy, and I’m kicking myself for not drying it first. Wet filament is the enemy of crisp 3D prints, and after that disaster, I swore I’d never skip a filament dryer again. If you’re like me—passionate about 3D printing perfect decor pieces for your home—choosing the right filament dryer is a game-changer.

Today, I’m pitting the Creality Space Pi Plus Filament Dryer against the Comgrow Filament Dryer Box to see which one’s worth your cash. Let’s dive in and find out which dryer keeps your PLA, PETG, and ABS in top shape!
Why You Need a Filament Dryer for 3D Printing
Ever notice your prints turning out stringy or brittle? That’s moisture wreaking havoc on your filament. Wet filament causes clogging, poor adhesion, and layer shifting—total buzzkills for any 3D printing project. A solid filament dryer like the Creality Space Pi Plus Filament Dryer or Comgrow Filament Dryer Box saves the day by keeping your filament dry and ready. Whether you’re printing plant pots or glow-in-the-dark decor, dry filament means better results. Let’s break down what these two bring to the table.
First Impressions: Creality Space Pi Plus Filament Dryer vs Comgrow Filament Dryer Box
Creality Space Pi Plus Filament Dryer
When I first unboxed the Creality Space Pi Plus Filament Dryer, I was stoked—it felt like a premium tool right out of the gate. The sleek design and that big 4-inch touchscreen screamed high-tech. I popped in a soggy roll of TPU I’d left in my basement for years, set it to dry, and wow, it came back to life! The heat kicked in fast, and I could see the temp and humidity ticking down in real time.
But then I tapped the screen a bit too hard, and I noticed some weird visual glitches—hairline cracks lit up for a sec. It still worked fine, but that cheap-feeling touchscreen left me a little bummed. Space-wise, I had to shuffle my workbench around because the lid needs room to swing open. Still, I could tell this thing meant business for drying filament.
Comgrow Filament Dryer Box
The Comgrow Filament Dryer Box hit me differently when I first got it. I pulled it out of the box, and it was lighter than I expected—almost like a big Tupperware container with a screen. I tossed in two PLA spools, flipped it on, and the little fan started humming quietly.
The 2-inch LCD lit up with temp and humidity readings, which was cool, but figuring out the buttons? Total headache. I kept accidentally changing settings because there’s no clear “start” button—it’s like a puzzle! Once I got it running, I felt the warmth and saw the humidity drop slow and steady. It’s not flashy, but I liked how it fit snugly next to my printer without hogging space. For the price, I thought, “Hey, this might just do the trick.”
Detailed Specs: Creality Space Pi Plus Filament Dryer
The Creality Space Pi Plus Filament Dryer is a beefy option for serious 3D printers. Here’s what it’s packing:
- Capacity: Holds two 1kg spools—perfect for big projects or dual-printer setups.
- Temperature Range: Adjustable from 45°C to 70°C.
- Heating Tech: 110W PTC heater with 360° hot-air circulation.
- Timer: 0-48 hours of drying time.

Comparison to 3 Other Popular Filament Dryers
How do these stack up against other dryers we’ve covered? Let’s compare them to the Sunlu Filadryer S4, Eibos Cyclopes, and Polymaker PolyDryer from our article The Best Filament Dryers for 3D Printing: Top 5 Picks.
- Sunlu Filadryer S4: Four-spool capacity, 35°C–70°C, $129. Bigger and pricier, but ideal for bulk drying.
- Eibos Cyclopes: Single-spool, 40°C–60°C, $69. Compact but lacks the dual capacity of Creality or Comgrow.
- Polymaker PolyDryer: Single-spool, 40°C–70°C, $99. Premium build, but overkill for casual users.
The Creality Space Pi Plus Filament Dryer beats the Eibos and Polymaker on capacity and matches the Sunlu’s temp range for less cash. The Comgrow Filament Dryer Box undercuts them all on price but sacrifices power.
