Customer Questions & Answers

  • Question: What is the purpose of the SUNLU Official Filament Dryer S1 Plus?

    Answer: The SUNLU Official Filament Dryer S1 Plus is designed to keep your 3D printing filament dry, which is essential for optimal printing performance. Moisture can cause filament to bubble, snap, or produce poor quality prints. This dryer features a built-in circulation fan that ensures even heat distribution, effectively removing moisture from the filament, making it suitable for various filament types including PLA, ABS, and PETG.
  • Question: How does the built-in circulation fan enhance the drying process?

    Answer: The built-in circulation fan in the SUNLU S1 Plus helps to maintain consistent airflow around the filament, which accelerates the drying process. This fan operates quietly while providing uniform heat distribution, preventing hotspots. This feature is particularly useful for users in humid environments where filament is prone to moisture absorption, ensuring you achieve high-quality prints every time.
  • Question: What types of filament can be dried in the SUNLU S1 Plus?

    Answer: The SUNLU Official Filament Dryer S1 Plus is versatile and can accommodate a variety of filament types including 1.75 mm, 2.85 mm, and 3.00 mm filaments. This versatility makes it a great tool for users who work with different materials, allowing you to prepare PLA, ABS, PETG, and more for optimal printing. By ensuring your filament is dry, you enhance print adhesion and reduce stringing and warping.
  • Question: How do I set up the SUNLU S1 Plus for use?

    Answer: Setting up the SUNLU S1 Plus is straightforward. Simply place your filament spool inside the dryer, connect it to a power source, and adjust the drying time and temperature settings based on the filament type. The user-friendly design makes it easy for anyone, from beginners to professionals, to prepare the filament for printing. Always refer to the specific settings recommended for your filament type for best results.
  • Question: How long does the drying process typically take?

    Answer: The drying process with the SUNLU S1 Plus varies based on the type of filament and initial moisture levels. Typically, drying times range from 2 to 8 hours. For example, PLA might take around 2 hours, while more moisture-absorbing materials like Nylon could require a longer duration. Monitoring the filament condition and adjusting the drying settings based on experience will optimize print quality.
  • Question: Can I use the SUNLU Filament Dryer S1 Plus while printing?

    Answer: Yes, the SUNLU Filament Dryer S1 Plus can be used while you are printing. Many users find this feature advantageous, as it ensures that the filament remains dry throughout the printing process. This continuous drying maintains filament quality and prevents moisture-related printing issues, allowing for more flexible workflow arrangements and minimizing downtime.
  • Question: What is the capacity of the SUNLU S1 Plus Filament Dryer?

    Answer: The SUNLU Official Filament Dryer S1 Plus has a generous capacity, designed to accommodate multiple filament spools simultaneously. It can hold a standard spool of 1.75 mm, 2.85 mm, or 3.00 mm filament. The spacious interior allows for easy loading and unloading of filaments, making it suitable for both home users and small businesses with higher printing demands.
  • Question: Is it safe to leave the dryer on for extended periods?

    Answer: The SUNLU S1 Plus is designed with safety in mind, featuring automatic shut-off after the designated drying cycle is complete. This helps prevent overheating and ensures safe operation during extended use. Users commonly leave the unit running overnight or while at work, enhancing convenience without sacrificing safety. However, always monitor for any unusual behavior during long sessions.
  • Question: How do I clean the SUNLU S1 Plus after use?

    Answer: Cleaning the SUNLU S1 Plus is minimal and straightforward. After each use, simply unplug the dryer and let it cool down. Wipe the interior and exterior surfaces with a soft, dry cloth to remove any dust or filament residue. Regular maintenance helps keep the dryer in optimal working condition and will prolong its lifespan, ensuring reliable performance for your 3D printing needs.
  • Question: Where can I buy the SUNLU Official Filament Dryer S1 Plus?

    Answer: You can purchase the SUNLU Official Filament Dryer S1 Plus through Ubuy. This platform offers a reliable shopping experience and a variety of payment options tailored for customers in Montserrat.

The upgraded dryer box by Sunlu is designed to heat filament to a temperature below its glass transition temperature (GTT) and maintain it for several hours. It claims to make filaments go smoother with less friction and a more stable temperature setting. The max temperature for this device is 55°C, which is important for absorbing moisture, especially with Nylon. The box comes with a timer function with a max time limit of 24 hours and an auto shut off feature. Unfortunately, it doesn't have an auto-start feature, and its instructions aren't very intuitive. Despite its flimsy construction and inadequate user manual, most buyers agree that it does its job well. It revived waterlogged filaments and improved print quality. However, some customers have reported that their units made a loud noise or a grinding sound and lacked a fan. Others have claimed that it’s not the best for feeding out material, while others recommend state that it works well. So, while there are better options at the same price range, the Sunlu Upgraded Dryer Box does its job, and it is a good investment if you print regularly and live in places with high humidity levels.
