Creality Space Pi Filament Dryer Plus Manual: Setup, Settings and Troubleshooting

This searchable Creality Space Pi Filament Dryer Plus manual covers loading one or two spools, touch controls, filament presets, custom temperature and time, PTFE routing, print-through drying, troubleshooting and maintenance.

The Creality Space Pi Filament Dryer Plus is a two-spool dryer with double PTC 360° hot-air heating, adjustable temperature from 45–70°C, a 0–48 hour timer, real-time temperature and humidity monitoring, and one-key settings for up to 12 filament types. Creality also provides a Space Pi Plus product manual and support hub for official downloads, videos and support resources.

Space Pi Plus Quick Specifications Feature Space Pi Filament Dryer Plus Capacity Up to two filament spools Temperature range 45–70°C Timer 0–48 hours Heating Double PTC 360° hot-air circulation Monitoring Real-time chamber temperature and humidity Presets One-key settings for up to 12 filament types Print-through Four filament outlets with PTFE routing for up to two printers Power-off memory Remembers previous material and temperature parameters after interruption 1. Unbox and Set Up the Space Pi Plus Inspect the dryer and accessories. Check the unit, power connection, PTFE tubes and documentation for visible shipping damage. Place the dryer on a stable, flat surface. Keep the air path unobstructed and leave enough room for the lid to open fully. Open the lid and place one or two spools on the internal rollers. Make sure each spool can rotate freely without rubbing the side wall. Choose the filament outlet. If you plan to print directly from the dryer, route filament through the appropriate top or side outlet and insert the PTFE tube. Close the lid and connect power. Turn the dryer on only after the filament is loaded and feeding smoothly. The Plus model can dry two rolls and feed two printers at once. If you only need one active spool, Creality's single-spool Space Pi uses the same 45–70°C temperature class.

2. How to Use the Touch Screen and Filament Presets After power-on, use the touch interface to select the filament type, drying temperature and time. The Space Pi Plus supports one-key settings for up to 12 common and composite filament categories. A preset is a convenient starting point, but the exact filament manufacturer's drying recommendation takes priority if it differs from a generic material preset.

Select the filament/material option. Choose the matching preset or switch to manual adjustment. Confirm the target temperature. Set the drying duration from 0 to 48 hours. Start the cycle and monitor real-time temperature, humidity and remaining time. For current starting temperatures and times by material, use Creality's Filament Dryer Temperature and Time Chart . It covers PLA, PETG, ABS, ASA, TPU and Nylon and explains why the set temperature is not necessarily identical to the temperature at every point around the spool.

3. How to Set a Custom Temperature and Time

Use manual settings when the filament label or technical data sheet specifies a different cycle from the built-in preset. Space Pi Plus can be adjusted between 45°C and 70°C. Do not exceed the filament maker's recommendation simply to shorten drying time, and check that the spool itself can tolerate the selected temperature.

Creality's general guidance uses 55°C for PLA/PLA-CF, 60°C for PETG, 65°C for ABS/ASA and 70°C for TPU, generally for 8–12 hours. These are references, not universal rules. If Nylon, PC or a composite specifies more than 70°C, use equipment capable of meeting that requirement.

If you are unsure whether the filament is actually wet, read Filament Dryer Guide: When You Need One and How to Choose before running repeated cycles.

4. PTFE Routing and Printing While Drying One of the main advantages of the Plus model is print-through drying. The enclosure has four filament outlets and PTFE routing so one or two spools can feed printers without being removed from the heated chamber.

Place the spool so filament unwinds in the natural direction toward the chosen outlet. Feed the filament through the outlet and into the PTFE tube. Keep the PTFE route as short and smooth as practical. Avoid tight bends that increase drag between the dryer and extruder. Pull filament by hand before printing to confirm the spool rotates smoothly. For moisture-sensitive materials, leave the dryer running during a long print if the material manufacturer recommends keeping the spool dry in use. If extrusion quality becomes worse only when feeding from the dryer, check spool rotation, PTFE bends and outlet alignment before changing slicer settings. Community users have occasionally reported excessive feed resistance when a spool or path does not rotate smoothly, so mechanical drag is worth ruling out early.

5. How to Read the Humidity Display

The humidity value is useful as a trend , not a direct measurement of water inside the filament. Chamber temperature, room humidity, spool moisture and airflow all affect the number.

Do not end a cycle simply because the RH display reaches a particular percentage. Use the filament maker's recommended time and verify the result with the print itself: less popping, fewer bubbles, cleaner surfaces and reduced moisture-related stringing are stronger evidence. Creality's How to Dry Filament guide explains how to compare the same test print before and after drying.

6. Space Pi Plus Troubleshooting Symptom What to Check Dryer will not power on Check the outlet, power connection and rear power switch; reconnect power before assuming a display fault. Filament still strings or pops after drying Verify material preset, actual drying time and temperature; confirm the symptom is moisture-related rather than retraction or nozzle temperature. Humidity does not fall as expected Judge RH as a trend; check room humidity, lid position and whether the cycle has had enough time to warm the spool. Filament is hard to pull through PTFE Check roller movement, spool width, PTFE bends and outlet alignment. Fan sounds unusually loud or grinding Place the unit on a stable surface and make sure airflow is unobstructed; stop use and contact support if the noise is abnormal. Touch screen is difficult to operate Power-cycle the dryer and avoid excessive pressure on the display; contact support if the interface remains unresponsive. An error code appears Photograph the code, power-cycle once, and use official Creality support. Do not guess the code meaning from unrelated models.

7. Cleaning and Maintenance Turn the dryer off and unplug it before cleaning. Remove filament dust and debris from the rollers and chamber with a dry, soft cloth. Keep PTFE outlets clear so filament does not scrape or bind. Check that both spools rotate freely before long unattended prints. Do not immerse the unit or use liquid cleaner near electronics, heater or fan openings. After drying, move unused filament to sealed storage if it will not be printed soon. For longer-term moisture control, see Creality's Filament Dry Box and Storage Guide . Active drying and long-term storage are different jobs.

FAQ What temperature range does Space Pi Filament Dryer Plus support? It can be adjusted from 45°C to 70°C. Use the exact filament manufacturer's drying recommendation within that range.

Can Space Pi Plus dry two spools at once? Yes. It is designed for two rolls and uses double PTC hot-air heating.

Can I print directly from the Space Pi Plus? Yes. The dryer provides four filament outlets and PTFE routing, allowing two spools to feed up to two printers while drying.

Does Space Pi Plus remember settings after a power outage? Creality states that the dryer retains previous material and temperature parameters after a power interruption, reducing the need to re-enter those settings.

Is Space Pi Plus suitable for Nylon? Only when the specific Nylon filament's required drying temperature is within the 45–70°C range. Many PA/PA-CF formulations require more than 70°C; for those, consider a higher-temperature dryer such as SpacePi X4 , which reaches up to 85°C.

Need More Capacity or Higher Temperature? Space Pi Plus is the two-spool choice for users working mainly within a 45–70°C drying range. If you only need one spool, choose Space Pi . If you need four spools and higher temperatures for engineering materials, compare SpacePi X4 . Creality's filament dryer comparison puts the current lineup side by side.

For owners who already have Space Pi Plus, the best workflow is simple: follow the spool manufacturer's drying instructions, keep the PTFE path low-friction, use humidity as a trend rather than an absolute moisture reading, and escalate persistent hardware or error-code problems through official Creality support.
