Struggling with wet filament ruining your prints? The Creality Space Pi X4 Filament Dryer is your ultimate fix. This filament dryer box is a game-changer for 3D printing pros, especially those working with moisture-sensitive filaments like PLA, PETG, TPU, and ABS. As the owner of 3dprinteddecor.com, I’ve tested many dryers, and the Creality Space Pi X4 Filament Dryer stands out for its moisture-free storage and fast drying. Let’s dive into why this filament dryer box is a must-have for 2025, with insights from a detailed review by Ken of Rist Innovations.

The Creality Space Pi X4 Filament Dryer is a powerhouse for 3D printing. It’s a 4-spool 3D printer storage box with dual independent heating chambers, each packing 200W of power and reaching up to 85°C. This makes it ideal for fast drying high-temperature filaments like polycarbonate (PC), nylon (PA6/PA12), and carbon-filled or glass-filled materials. Unlike most dryers capped at 70°C, the Creality Space Pi X4 Filament Dryer handles engineering filaments with ease, though it falls short for PPA-CF and PPS-CF, which need 100°C+.
Compact at 382mm x 290mm x 270mm and weighing just 1.2kg, it fits four 1kg spools (200mm diameter, 150mm width) or two 2kg spools across two chambers. You can dry different filament types at separate temps simultaneously, perfect for multi-material 3D printing. The moisture-proof sealing design and illuminated window let you check spools without letting humidity sneak in. Curious about other dryers? See our top filament dryers guide.
Top Features of the Creality Space Pi X4 Filament Dryer
Here’s what makes the Creality Space Pi X4 Filament Dryer a top pick for filament storage and 3D printing success.
High-Temperature Drying at 85°C
With dual 200W PTC heaters, the Creality Space Pi X4 Filament Dryer hits 60°C in 10 minutes and 85°C in 15 minutes, drying filaments 30% faster than single-chamber models. It’s perfect for PLA (50°C), PETG/TPU (60°C), and ABS/PA/PC (80-85°C). Ken tested TPU and PA6-CF, noting significant print quality improvements after drying at 60°C and 80°C for 8 hours, reducing stringing and defects.
Spacious and Versatile Storage
This filament dryer box holds four spools, with rollers for smooth feeding to your printer during printing. Connect via PTFE tubing through four exit holes to maintain moisture-free storage. It supports 1.75mm and 2.85mm filaments, making it a great match for printers like the Creality K1C.
Dual Chambers with Independent Control
Each chamber has its own heater and fan for 360° hot air circulation, ensuring even drying. Set different temps for each chamber (e.g., PLA in one, ABS in the other), though Ken noted a 1-5°C temp difference between chambers, which is normal. This flexibility is ideal for multi-color printing.
Smart SpaceDry 4.0™ Technology
The Creality Space Pi X4 Filament Dryer features active dehumidification with dual fans and auto-regenerating desiccants, eliminating manual upkeep. Ken’s tests showed humidity dropping from 47% to 15% in hours, ensuring moisture-free storage. The one-way valve design keeps humid air out post-drying.
Energy-Saving and Safe
Choose single-chamber mode to save 40% energy (0.124kWh vs. 0.208kWh for dual mode at 85°C). Triple safety protection includes auto-pause for abnormal fan speed or temps and a self-resetting PTC fuse. This makes it a safe addition to your 3D printing workspace.
Intuitive 3.2″ Touchscreen
The EDry UI on a 3.2″ color LCD lets you set temps (45-85°C) and drying times (1-48 hours). It displays real-time temp, humidity, and progress. Ken loved the visual temp graphs, though some users report a 3-4°C overshoot, so check sensitive filaments like HTPET (filament compatibility guide).
Real-World Performance: Ken’s Tests
Ken from Rist Innovations tested the Creality Space Pi X4 Filament Dryer with TPU and PA6-CF exposed to high humidity (60-90%) and rain. Wet TPU showed heavy stringing in Death Racer tracks (Real Sam Prentice’s project). After drying at 60°C for 8 hours, stringing was “greatly reduced.” For PA6-CF, a pipe wrench from 3DPrintedHardware.com had defects when wet but improved significantly after drying at 80°C for 8 hours, especially in thread quality. An empty chamber test hit 85°C in 15 minutes, proving fast drying efficiency.
Pros and Cons of the Creality Space Pi X4 Filament Dryer

User Reviews and Value
Users rave about the Creality Space Pi X4 Filament Dryer. Eric Peterson (5 stars, August 3, 2025) called it a “powerhouse” for multi-toolhead setups. MT (5 stars, August 7, 2025) loved its simplicity for filament storage. QJ (4 stars, July 11, 2025) noted the temp overshoot but praised its value. With a 4.8/5 rating from 8 reviews and 100+ purchases, it’s a top choice for moisture-free storage (filament dryer reviews).
At $159 (down from $199, with a Prime Day deal at $149 until July 11, 2025), it’s a solid investment for 3D printing pros. For PLA/PETG users, the Creality Space Pi Plus at $89.99 is a cheaper alternative, but it’s limited to 70°C.
