How Creality SpacePi X4 Redefines Filament Drying

Since launching the original SpacePi and SpacePi Plus filament dryer, Creality has continued listening to users across the global 3D printing community—makers, professionals, and small farm operators alike. In response to their growing needs, we’re proud to unveil SpacePi X4 , the most advanced and user-focused filament drying solution in our lineup.

But how does SpacePi X4 compare to its predecessors? In this blog, we’ll walk you through the evolution of the SpacePi series —from the original single-spool version to the dual-spool edition, and now to the 4-spool powerhouse that is SpacePi X4—to show you how far we’ve come.

A Quick Look Back: The Original SpacePi Series The first-generation SpacePi introduced a much-needed solution to the problem of filament moisture. Available in single-spool and dual-spool configurations, these units offered reliable drying with PTC heating, temperatures up to 70°C , and sealed storage. However, both versions came with a single heating chamber , no active dehumidification , limited temperature customization , and no smart UI . Effective, yes—but built with hobbyist-scale needs in mind.

The Game Changer: SpacePi X4 Enter SpacePi X4 , designed not only to scale with your creativity but to solve the limitations of its predecessors. Whether you're a multi-color printing enthusiast or managing a small FDM print farm, X4 is made to meet your workflow head-on.

4-Spool Capacity No more batch-drying. X4 supports up to four 1kg filament spools simultaneously, allowing you to prep multiple colors or materials in one go—ideal for multi-material or long-duration prints.

Dual Independent Heating Chambers Each pair of spools is housed in its own chamber, with a dedicated PTC heater capable of reaching up to 85°C . This means you can dry two different types of filaments at the same time , each at its optimal temperature—critical for engineering materials like nylon, PC, or PPA .

True Moisture Control Unlike earlier models that relied solely on passive sealing, the X4 features active humidity extraction —automatically venting moisture without user intervention. No more manual lid cracking or opening mid-cycle.

Smarter UI, Better Control The X4 debuts the first intelligent drying interface in the industry, purpose-built for 3D printing users. Set precise temps, monitor humidity levels, and track drying status with ease. It’s filament care, finally made intuitive.

Why Upgrade to X4?

Feature SpacePi (1&2 Spool) SpacePi X4 Spool Capacity 1–2 4 Drying Chambers Single Dual Independent Temp Range 45–70°C Up to 85°C Active Dehumidification ✘ ✔ Smart UI ✘ ✔ Material Compatibility Basic Basic + Engineering Filaments My Drying Profiles ✘ 3 customizable presets for quick access Auto Lighting ✘ Dual auto LED lights; on during drying, off after Screen Type Digital display 3.2" IPS touchscreen Desiccant Regeneration ✘ Built-in; maintenance-free desiccant With more capacity , smarter drying , and greater control , SpacePi X4 is more than an upgrade—It's a redefinition of what filament drying should be in the modern 3D printing workflow.

Broader Use Cases, Truly Made for 3D Printing Compared to the first-generation models that only supported basic drying, the X4 is far better suited for multi-color 3D printer users and small to mid-sized print farm operators. It excels in the following scenarios:

Preparing multiple spools and colors for long-duration, multi-material prints High-temperature drying for a wide range of engineering-grade materials Batch production workflows where print stability is critical Long-term storage of filaments requires consistent moisture protection

Recommended Drying Temperatures Filament Type Recommended Temp PLA 50°C PETG 65°C TPU 60°C ABS / PC / ASA / PAHT 80–85°C Always refer to your filament manufacturer’s guidelines for optimal drying performance.

Wide Filament Compatibility The SpacePi X4 supports both 1.75mm and 2.85mm filament diameters, as well as 1kg and 2kg spools (diameter ≤200mm, width ≤150mm). It works seamlessly with PLA, PETG, TPU, ABS, ASA, PA, PAHT, PC, and more. Dry, store, and prep filaments without switching devices.

Real-World Applications Multi-Color Printing: Dry different materials simultaneously for flawless color transitions. Print Farms: Increase uptime with batch filament drying and long-term storage. Engineering Projects: Achieve high mechanical strength by properly drying PA-CF, PPA, or PC before use. Pro Tip : Stack two units to expand capacity to 8 spools—perfect for industrial or multi-user setups.

Final Thoughts SpacePi X4 represents Creality’s deepening commitment to the evolving needs of 3D printing users. By building on the proven foundation of the original SpacePi and pushing the boundaries of drying technology, we’re giving creators and professionals the tools they need to produce their best work consistently and confidently.
