3. Setup Guide
- Unpacking: Carefully remove the SpacePi X4L from its packaging. Inspect for any damage during transit.
- Placement: Place the dryer on a stable, level surface away from direct sunlight, heat sources, and excessive humidity. Ensure adequate ventilation around the unit.
- Loading Filaments:
- Open the chamber lids.
- Place your filament spools onto the anti-scalding rollers inside the chambers. The dryer accommodates spools up to 200mm in diameter and 150mm in width.
- Ensure the filament diameter is either 1.75mm or 2.85mm.
- Close the lids and secure them with the sliding locks.
- If printing directly from the dryer, feed the filament through the soft silicone tube connector at the top or rear outlet, then connect it to your 3D printer using a 4mm PTFE tube.
- Power Connection: Connect the power adapter to the dryer and then plug it into a suitable power outlet (e.g., US Plug, EU Plug, Brazil Plug - 110V/220V depending on your model).
4. Operating Instructions
- Power On: Press the power button on the unit. The LCD touchscreen will illuminate.
- Using the LCD Touchscreen: The touchscreen allows you to set drying parameters.
Figure 4.1: LCD Touchscreen Interface. - Setting Temperature: Use the controls on the touchscreen to adjust the drying temperature. The SpacePi X4L can reach up to 75℃.
- Setting Drying Time: Set the desired drying duration using the touchscreen controls.
- Selecting Chamber Mode:
- Dual Chamber Mode: Allows independent temperature settings for each chamber, ideal for drying different filament types simultaneously (e.g., one at 50℃, another at 75℃).
- Single Chamber Mode: For drying one type of filament or when only one chamber is in use. This mode is more energy-efficient.

Figure 4.3: Energy consumption comparison for drying modes. - Auto-Drying Mode: Activate the auto-drying mode for continuous humidity monitoring and automatic adjustments to keep filament optimal.
- Filament Compatibility: The SpacePi X4L supports common filaments like PLA, PETG, ABS, ASA, PET, PA, PC, TPU, and their variations. For best results, follow the drying temperature recommended by the filament manufacturer. Filaments requiring higher temperatures can still be dried, but with longer drying times.
- Drying While Printing: It is recommended to dry the filament thoroughly before printing. Once dried, you can feed the filament to your printer using a 4mm PTFE tube connected to the dryer's outlet. This allows for seamless multi-filament drying and printing.
- Power Off: Press and hold the power button to turn off the unit.
5. Maintenance
- Cleaning: Regularly wipe the exterior of the dryer with a soft, dry cloth. Ensure the unit is unplugged before cleaning. Do not use abrasive cleaners or solvents.
- Chamber Cleaning: Periodically inspect the interior chambers for any filament debris or dust. Clean with a soft brush or cloth.
- Desiccant Regeneration: The advanced PTC technology includes desiccant regeneration during the drying process, helping to maintain a low humidity environment. No manual desiccant replacement is typically needed under normal operating conditions.
- Moisture-proof Sealing: Ensure the chamber lids are properly closed and the sliding locks are engaged to maintain the moisture-proof seal.
6. Troubleshooting & FAQ
Common Issues:
- Poor Print Quality (Stringing, Clogs, Layer Shifts, Poor Adhesion): Moist filaments are a primary cause. Ensure filaments are thoroughly dried using the SpacePi X4L before printing. Refer to filament manufacturer guidelines for recommended drying times and temperatures.
Figure 6.1: Impact of moist vs. dry filament on print quality. - Overheating: The SpacePi X4L is equipped with dual overheat protection. Built-in PTC self-resetting fuses automatically cut power if overheating occurs, reconnecting once the temperature returns to normal. NTC sensors monitor the outlet and will instantly pause the drying process if an abnormality is detected.

Frequently Asked Questions:
- Q: What is the difference between SpacePi X4 and SpacePi X4L?
- A: The SpacePi X4L is the LITE version of SpacePi X4. Its maximum drying temperature is 75℃, and its screen is adjusted to a digital screen. It also features the function of dual-chamber independent drying.
- Q: What types of filaments can SpacePi X4L dry?
- A: SpacePi X4L supports drying common filaments like PLA, PETG, ABS, ASA, PET, PA, PC, TPU, and their variations. For best results, follow the drying temperature recommended by the filament manufacturer. Filaments needing higher temperatures can still be dried, but with longer drying times.
- Q: Can I use 3kg or 5kg spools?
- A: As long as the spool diameter is ≤200mm, width ≤150mm, and filament diameter is 1.75mm or 2.85mm, it should be compatible.
Figure 6.3: Spool and filament compatibility. - Q: Can I dry filament while printing?
- A: We recommend drying the filament thoroughly before printing. Drying time varies by material; refer to the user manual or the manufacturer's guidelines. Once dried, you can feed the filament to your printer using a 4mm PTFE tube.
- Q: Can I use CFS and SpacePi X4L together?
- A: Yes, we suggest drying filament fully in SpacePi X4L before transferring it to CFS for printing. While CFS is in use, you can pre-dry and store the next batch in SpacePi X4L, improving workflow efficiency without occupying CFS resources.

8. User Tips
- Pre-Drying is Key: Always pre-dry your filaments, especially hygroscopic types like PA-CF, before starting a print. This significantly improves print quality by preventing stringing, clogs, and poor layer adhesion.
- Optimize Drying Times: Consult your filament manufacturer's recommendations for specific drying times and temperatures. While the SpacePi X4L can reach 75℃, some filaments may require less, and others might benefit from longer drying durations at lower temperatures.
- Utilize Dual Chambers: Take advantage of the dual independent heating chambers to dry different filament types simultaneously, each at its optimal temperature, maximizing efficiency for multi-material projects.
- Energy Efficiency: If drying only one type of filament or fewer spools, consider using the single-chamber mode to reduce energy consumption.
- Check Spool Dimensions: Before loading, ensure your filament spools fit within the dryer's maximum dimensions (200mm diameter, 150mm width) to avoid issues.
- Print Directly: For best results and to prevent re-absorption of moisture, print directly from the dryer using the provided filament outlets and a PTFE tube.
