## Summary description

Sunlu S1 Plus Filament Dryer is a dedicated filament drying device for 3D printing that removes moisture to improve print quality and reduce printing issues. Designed by Sunlu, the unit accepts standard filament spools and provides controlled drying to help preserve PLA, ABS, PETG and other hygroscopic filaments. It is suitable for hobbyists and professionals seeking reliable filament conditioning before printing.

## Long description

The Sunlu S1 Plus Filament Dryer is a desktop drying unit for 3D printing filaments that removes moisture to improve print reliability and part quality. It supports common filament materials such as PLA, PLA+, PETG, ABS and TPU, and accepts standard spools up to Ø210 × 85 mm. With a clear LCD and simple two-button control, the device provides controlled drying during storage or even while printing.
Advantages
The Sunlu S1 Plus offers adjustable temperature (35–55°C) and a programmable drying time up to 24 hours, enabling you to tailor the drying process to different materials and ambient conditions. It operates quietly (\<10 dB), features internal rollers for feeding filament directly from the dryer during printing, and supports all standard filament diameters (1.75 mm, 2.85 mm, 3.00 mm). The compact design and intuitive display make setup and use straightforward.
Suitable for
Hobbyists and makers working with PLA, PETG, ABS, TPU and similar filaments
Professional or frequent users who need consistent filament conditioning
Users who want to dry filament during printing to maintain stable humidity
When it may not be suitable
The Sunlu S1 Plus is designed for standard spool sizes up to Ø210 × 85 mm; very large or non-standard spool formats may not fit. It is optimized for filament conditioning rather than high-volume industrial drying, so production environments with very large throughput may require a different solution.
Key specifications

Operating time range: 0–24 hours (default drying time 6 hours)
Noise level: \<10 dB
Supported filament diameters: 1.75 mm, 2.85 mm, 3.00 mm
Maximum spool size: Ø210 × 85 mm
Material compatibility: PLA, PLA+, PETG, ABS, TPU and other hygroscopic filaments
Display: LCD
How to use
Place a compatible filament spool inside the dryer, set the required drying temperature (35–55°C) and the drying time up to 24 hours using the two-button interface and LCD display. If you need to feed filament directly to a 3D printer, route the filament through the included Teflon tube and use the internal rollers to allow printing while drying. Typical drying sessions last 3–6 hours for most filaments, but adjust time and temperature according to material and humidity.
What to consider before purchase
Check that your filament spool dimensions do not exceed Ø210 × 85 mm
Verify the filament diameter (1.75 mm, 2.85 mm, or 3.00 mm) is supported
Decide whether drying during printing is required for your workflow
Ensure the 35–55°C temperature range is suitable for the materials you use
Usage recommendations
For most common filaments, start with a temperature around 40–50°C and a drying time of 3–6 hours; increase time for heavily moisture-absorbed or older filaments. When printing directly from the dryer, route filament smoothly through the Teflon tube to avoid tension or snagging.
