Creality Filament Dryers Compared: Space Pi, Plus, X4 and X4L

If you are comparing a Creality filament dryer , the real choice is no longer simply “one spool or two.” The current Space Pi family ranges from compact 70°C single-spool drying to four-spool, dual-chamber systems that reach 75°C or 85°C and are designed for more demanding materials.

This page focuses specifically on Creality model-to-model buying decisions . If you are still deciding whether you need a dryer at all, what wet filament looks like, or how drying differs from storage, start with the Filament Dryer Guide: When You Need One and How to Choose . For material-specific drying temperatures, use the Filament Dryer Temperature and Time Chart .

Creality Filament Dryer Comparison at a Glance Model Capacity Temperature Independent Chambers Moisture Control Published Rated Power Best Fit Space Pi 1 spool 45–70°C No PTC hot-air circulation; real-time humidity display 145W Everyday single-spool PLA, PETG, TPU and ABS/ASA workflows Space Pi Plus 2 spools 45–70°C No Double PTC hot-air heating; real-time temperature and humidity Not currently listed on the US Store product page Two-spool users, support material and dual-printer workflows SpacePi X4L 4 spools 45–75°C Yes, 2 chambers Independent PTC heating, humidity monitoring, insulated chambers 340W Four-spool capacity when 75°C is enough SpacePi X4 4 spools 45–85°C Yes, 2 chambers Active dehumidification, sealing, desiccant regeneration 360W Engineering filaments, mixed-temperature workflows and advanced users Important: rated power is not the same as real energy use. Duty cycle, target temperature, room temperature and single- vs dual-chamber operation all affect consumption. Creality publishes an X4 example of 0.124 kWh for one chamber and 0.208 kWh for both chambers during a one-hour 85°C test, but equivalent same-condition figures are not currently published for all four models.

Space Pi: Best for One Active Spool The Creality Space Pi Filament Dryer is the simplest current Space Pi choice for users who normally print one material at a time. It provides 45–70°C adjustment, a 0–48 hour timer, real-time humidity monitoring, a 3.7-inch touch screen and 360° PTC hot-air circulation.

Creality lists a rated power of 145W and an 80W PTC heater. The key advantage is compactness: if one spool of PLA, PETG, ABS/ASA or TPU is normally all you need beside the printer, there is little reason to dedicate desk space and power capacity to a four-spool machine.

Choose Space Pi if: you want one spool, print mostly common materials within a 70°C drying ceiling, and value a touch interface and print-through drying without paying for multi-spool capacity.

Space Pi Plus: Best for Two-Spool Workflows The Space Pi Filament Dryer Plus keeps the same 45–70°C temperature class but expands capacity to two rolls. Creality uses double PTC 360° hot-air heating, real-time temperature and humidity monitoring, a 0–48 hour timer and one-key settings for up to 12 filament types.

Its four filament outlets and PTFE routing make it useful for two printers, dual-material workflows or keeping a support spool and a primary material dry together. Unlike X4L and X4, however, Plus does not divide the dryer into two independently controlled temperature chambers. Both spools therefore belong to the same drying environment.

Choose Space Pi Plus if: two spools are enough, both materials can use similar drying conditions and you mainly work with PLA, PETG, TPU, ABS/ASA or other filaments whose manufacturer recommendation stays within 70°C.

SpacePi X4L: Four Spools Without the 85°C Premium The SpacePi X4L moves to four-spool capacity and, importantly, two independently controlled chambers . Each chamber has its own PTC heater, so two material groups can run at different temperatures at the same time.

X4L reaches 75°C, uses dual 200W PTC heaters and has a published rated power of 340W. It supports single- or dual-chamber operation, and Creality states that using one chamber can save up to 40% energy compared with operating both. The two-layer insulation and humidity monitoring are useful for batch preparation, while 1 kg and 2 kg spools up to the published size limit are supported.

What X4L does not add is equally important: the current official product page does not list the X4's active dehumidification and automatic desiccant-regeneration system. X4L is therefore primarily the capacity-focused option.

Choose SpacePi X4L if: four spools and independent chambers matter more than the highest possible temperature or X4's more advanced moisture-management features. For a deeper product explanation, read Why Choose SpacePi X4L .

SpacePi X4: Best for Engineering Materials and Advanced Moisture Control The SpacePi X4 is the highest-temperature model in this comparison. It handles four spools across two independent chambers and reaches up to 85°C with dual 200W PTC heaters. Creality lists a 360W rated power.

The extra temperature headroom matters when the filament manufacturer calls for hotter drying. Creality positions X4 for materials such as PA, PAHT and PC, while its official drying reference also makes clear that users should follow the exact filament manufacturer's temperature rather than assuming every Nylon formulation fits one schedule.

X4 also adds the biggest moisture-control difference in the lineup: dual dehumidifying fans actively expel moisture, one-way valves help maintain sealing after drying, and the heated airflow automatically regenerates the internal desiccant. It can operate one chamber when only two spools need treatment, or both chambers with different materials at different temperatures.

Creality's published 85°C test shows 0.124 kWh for one chamber and 0.208 kWh for dual-chamber operation over one hour. The official SpacePi X4 overview also describes an Auto Silent mode and reports a 46–48 dB operating range, but there is no equivalent same-condition noise figure for every Space Pi model, so it would be misleading to declare a cross-model noise winner from published data alone.

Choose SpacePi X4 if: you regularly dry Nylon/PA, PAHT, PC or other hotter materials, need independent temperature zones, want sealed storage after drying, or prefer active moisture removal instead of relying on heated circulation alone.

How Should You Compare Heating Speed, Temperature, Noise and RH Drop? Marketing specifications are useful, but a fair dryer comparison needs the same test conditions. If Creality adds normalized lab data to this page later, the most useful protocol would be:

Use the same room temperature and starting humidity. Load the same spool type and approximate spool mass. Set every compatible dryer to the same target temperature. Record time to reach target, then temperature at multiple points around the spool. Measure wall-plug energy rather than comparing rated wattage alone. Measure noise at the same distance and room background level. Record chamber RH over time, while remembering that RH naturally changes as temperature rises. Finish with the same print file before and after drying to verify whether the filament actually improved. Until those same-condition measurements exist for every model, this comparison uses official specifications and published product data rather than inventing cross-model test results.

Space Pi vs Plus vs X4L vs X4: Which Should You Buy? Buy Space Pi if one spool and a 70°C ceiling cover your normal workflow. Buy Space Pi Plus if two spools are regularly in use and they can share similar drying conditions. Buy SpacePi X4L if four-spool capacity and dual independent chambers matter, but 75°C is sufficient. Buy SpacePi X4 if you want four spools, 85°C, active dehumidification, desiccant regeneration and the widest engineering-material capability in the current Space Pi range. If filament is already wet, active drying is only part of the workflow. After drying, sealed storage helps prevent moisture from returning. Creality's Filament Dry Box and Storage Guide explains that distinction, while How to Dry Filament covers alternative drying methods and temperature-control risks.

FAQ What is the best Creality filament dryer for PLA and PETG? For one spool, Space Pi is the most compact fit. Choose Plus if you want two spools ready together. X4L and X4 are mainly justified when four-spool capacity or independent chambers matter.

What is the difference between Space Pi Plus and SpacePi X4L? Space Pi Plus holds two spools in one 45–70°C drying environment. X4L holds four spools across two independently controlled chambers and reaches 75°C.

What is the difference between SpacePi X4L and X4? Both hold four spools and use dual independent chambers. X4L reaches 75°C, while X4 reaches 85°C and adds active dehumidification, desiccant regeneration, moisture-proof sealing and a more advanced touch interface.

Which Creality filament dryer is best for Nylon? SpacePi X4 provides the highest temperature in this lineup at 85°C. However, some Nylon and engineering filaments require more than 85°C, so always follow the exact filament manufacturer's drying specification.

Can I print directly from Creality filament dryers? Yes, the Space Pi family provides filament outlets for feeding to a printer. For X4 and X4L, Creality recommends thoroughly drying first and then feeding through a compatible PTFE tube.

Final Recommendation For most buyers, capacity and maximum required temperature should decide the model before screens or presets. Space Pi is the efficient one-spool choice; Plus doubles capacity without changing the 70°C ceiling; X4L adds four-spool dual-zone drying at 75°C; and X4 is the step-up option for hotter engineering materials and stronger moisture-management features.
