Creality SpacePi X4 – filament dryer with two independent chambers
Key advantages
- Capacity for up to 4 spools for parallel preparation of materials for 3D printing.
- Two independent chambers with separate control – convenient for different materials in one working day.
- Temperature range 45–85°C and timer 1–48 h for adjustment according to the material.
- Active moisture extraction + automatic desiccant regeneration to maintain low humidity.
- 3.2" color touchscreen with presets and manual settings, plus process monitoring.
Who is Creality SpacePi X4 for and when does it have a real effect
Moisture is one of the most common "hidden" sources of instability in 3D printing: from stringing and bubbles on the surface to unstable extrusion, clogs, and weaker adhesion between layers. This is exacerbated with hygroscopic materials (nylons/PA, polycarbonate/PC, etc.) and in environments with higher relative humidity. Creality SpacePi X4 is designed to maintain a controlled environment for drying and storing filament, so the material enters the extruder in a more predictable state.
The practical benefit is most strongly felt in three situations: (1) long prints, where the filament sits exposed for hours; (2) engineering materials that "absorb" moisture quickly; (3) multi-material/multi-color workflows, where spools are changed and none should be "returned" wet in the process.
Drying technology: two chambers, PTC heaters, and a range of 45–85°C
SpacePi X4 uses two independent drying chambers, allowing for parallel operation with different materials and settings. From a control perspective, this is key: the temperatures suitable for PLA are not the same as for PA/PC. Heating is implemented with PTC heaters (rated as 200 W + 200 W), and the set temperature range is 45–85°C.
The drying timer is 1–48 hours, providing flexibility: short cycles for "refreshing" material before work and longer cycles for heavily humidified filament or more demanding engineering materials.
Active defh. and stable environment: moisture extraction, desiccant, and 360° circulation
Unlike solutions that primarily rely on passive "evaporation," SpacePi X4 is positioned as a system with active moisture extraction and automatic desiccant regeneration. The idea is not only to heat the material but also to remove moisture from the chamber so that it does not "circulate" inside. Additionally, 360° circulation of heated air is described for more even drying within the chamber.
In the context of the workflow, this has two practical consequences: first, drying is more predictable for materials with critical moisture behavior (for example, nylons and PC); second, the filament can remain in a more protected environment even after the cycle ends, which reduces the risk of re-humidification between drying and printing.
Performance and workflow: how to use it (including "Dry & Print")
The control is through a 3.2" color touchscreen with a logical structure and presets by material type, as well as the option to manually set temperature and time. This is important because in a real environment, different brands of filament behave differently, even when they are the same material "on the label."
Basic workflow (recommendation):
- Check if the spool fits in size (diameter/width) and place the filament in the corresponding chamber.
- Select a preset by material or manually set the temperature and time according to the filament manufacturer's recommendations.
- Start the cycle and monitor the readings; adjust the settings if necessary.
- At the end of the cycle, leave the spool closed in the chamber if it will not be used immediately.
For longer tasks, the feature of feeding filament directly to the 3D printer through passthrough holes ("Dry & Print" passthrough) is useful, so the material remains at low humidity during printing. This is especially practical with engineering materials and in environments with unstable humidity.

Compatibility and ecosystem: spools, diameters, and materials
SpacePi X4 is designed for up to 4 spools (two chambers, each holding up to two spools). It supports 1.75 mm and 2.85 mm filaments, and the maximum spool size is specified as diameter ≤ 200 mm and width ≤ 150 mm. This covers a large part of standard spools, including configurations with 1 kg and 2 kg.
As a temperature potential (up to 85°C), the device is aimed at materials that practically benefit the most from moisture control: PA/nylons, PC, as well as other engineering filaments and composites. Independent tests have shown distinct improvements in printing with engineering materials after drying (smoother surface, less stringing/oozing, and cleaner bridges), which is a good indicator of a real effect beyond marketing descriptions.
Important clarification regarding expectations: SpacePi X4 is a dryer/filament box, not an automatic material switching system. It helps keep the filament in the right condition for printing, but does not "mix" or manage multi-color printing like multi-material modules.
Technical specifications, scenarios, and best practices
Design and daily ergonomics
The case has two separate lids/locks for the chambers and a front touchscreen. According to product specifications: nominal power 360 W, power supply 100–120 V~ / 220–240 V~ (50/60 Hz), net weight 5 kg and dimensions 382 × 290 × 270 mm. This is a format that fits well next to a 3D printer in a workspace without "eating up" an entire table.

Professional scenarios (4–6)
- Small "farms" with several 3D printers: four ready spools reduce interruptions when changing material and allow parallel tasks.
- Multi-material prototypes: separate chambers = lower risk of "overheating" sensitive material while drying another.
- Engineering materials (PA/PC and composites): fewer moisture defects (strings, unstable extrusion), more predictable part mechanics.
- Long prints: feeding from the chamber ("Dry & Print") reduces re-humidification during the process.
- Training/shared workshops: more stable results among different operators because the material is "standardized" in condition.
Limitations and best practices
- No active spool rotation: spools remain static; air circulation is relied upon. For very tightly wound filament or very large spools, plan for a longer cycle.
- The temperature is not "one size fits all": follow the filament manufacturer's recommendations and avoid unnecessarily high temperatures that can deform spools/material.
- Minimize openings: each opening introduces moisture and cools the chamber, extending the actual time to a stable result.
- For the most sensitive materials: dry before printing and feed directly from the chamber for long tasks.
