If you’ve ever dealt with moisture-soaked filament, you already know how fast it can ruin a great print. Stringing, popping, weak layers, failed supports… all the fun stuff that makes you question every life decision that led you to 3D printing.
So when the Creality Space Pi X4 started getting a ton of buzz, I had to see whether it actually solves the moisture headache, or if it’s just another fancy box that blows warm air.
True Dual-Chamber Drying
First up, the big feature: two fully independent chambers, each with its own temperature control. Not shared heat. Not “kind of separate.” Actually separate. That means, for example you can dry PLA on one side while drying a different material type like ASA, Nylon, ABS, or TPU on the other. In my first tests, I dried PLA at 50 °C on one side and ASA at 80 °C on the other without any issues.
- Holds up to four 1kg spools (two per side)
- Supports PLA, PETG, ABS, ASA, TPU, Nylon, PC, and more
- A lifesaver if you run multi-material prints or multiple printers
- Dual Desiccant tray – One each side
You can also switch between single and dual chamber sides, allowing for more energy efficient drying when you only need to dry one or two rolls of filament.
A Touchscreen That Doesn’t Make You Hate Technology
So most filament dryers have interfaces that feel like they came off an old clunky piece of tech. The Pi X4’s 3.7” LCD touchscreen is actually modern, responsive, and easy to use. It feels like the UI filament dryers should have had all along. It was so intuitive that I never needed to open the manual.
- Clean menus
- Tap-and-go presets
- No hunting for the “secret” button combo to change temps
Smart Auto-Sensing & Fan Control
The Pi X4 isn’t just a hot box, it actually reacts to what’s going on inside. It’s very much a “set it and forget it” system, and it works really well. Just put in your filament select from the preset and press start. You can also fine tune temps and drying times if you prefer.
- Auto-dry mode kicks in when internal humidity rises
- Intelligent fan control keeps noise surprisingly low
- A one-way moisture valve helps maintain stable drying conditions
Thoughtful, Maker-Friendly Design
Creality clearly listened to user feedback here. The dryer has a Silicone gasket for an airtight seal. 8 ports in total so you can print straight from the dryer. Front opening lid with a sliding lock. Plus the excellent touch screen for easy control, and its all nicely designed and well built.
Each bay has good compatibility with filament spools – 1kg or 2kg spools fit and it works perfectly with all standard filament diameters 1.75/2.85mm. Max Spool Size Diameter ≤ 200mm, Width ≤150mm
For the dimensions its 382mm across the front x 290mm deep x 270mm height. By the way if your thinking about placing it on a shelf with limited space, with the lid fully open the height measures 560mm, but you can slide in a spool of 1kg filament with the lid only slightly open at about 440mm.
- Front and rear filament pass-through ports.
- Sliding lock top lid
- SD card slot (tucked under the front lip) for firmware updates
Fast, Even Heating (Surprisingly Fast)
Thanks to the dual 200W PTC heaters, paired with insulated chambers 360° circulation system, the Pi X4 gets up to temp quickly and evenly and able to reach temps upto 85°C. In my tests starting at a room temp of 20c it took approx the following to heat up:
| Temp (°C) | Time (min:sec) |
| 20c Ambient Temp Start | 0:00 |
| 30c | 0:30 |
| 40c | 1:20 |
| 50c | 2:30 |
| 60c | 4:24 |
| 70c | 6:30 |
| 80c | 9:16 |
| 85c Max | 11:00 |
- ~4.5 minutes to reach 60°C
- ~11 minutes to reach 85°C
Supports Pretty Much Everything
With support for 12 filament types, the Pi X4 covers nearly all consumer and prosumer materials. PLA, PETG, ABS, ASA, TPU, PC, PA (Nylon), and more. Only extreme high-temp filaments (like PPA-CF or PPS-CF) sit out of range since 85°C is the top end.
Power-Loss Memory
It’s a small feature, but I love it. If the power goes out, the X4 remembers your settings and resumes automatically. For anyone printing from the dryer during long jobs, this is peace of mind.
You can choose to turn LEDs on manually or set it to automatic mode. In automatic mode, the light will turn on automatically when drying starts and turn off when drying ends.
Final Verdict: Is the Creality Space Pi X4 Worth It?
Yes, without a doubt, especially for multi-material users or anyone printing regularly. It’s a bit pricier than single-bay dryers or basic units. But considering the dual chambers, touchscreen interface, and overall build quality, most users find it well worth the investment.
The Creality Space Pi X4 sets a new standard for what a high-quality filament dryer should be. With its dual-chamber design, intelligent humidity control, fast heating performance, and maker friendly features, it delivers one of the most complete filament drying experiences available today.
If the four bay setup feels like overkill? And if you only print occasionally or stick to basic PLA, this may be more than you need. Creality also makes the Space Pi a compact single-chamber version, of my most used dryers (review here) and the Space Pi Plus (2 spool) if you want something middle-ground.
