SUNLU FilaDryer SP2: Efficient Drying and Reliable Filament Storage
The SUNLU FilaDryer SP2 is a modular dual-function system designed for efficient drying and long-term storage of 3D printing filament. The design with a removable heating platform and drying chamber allows for effective moisture removal from the material and provides convenient plastic feeding directly during printing. The dryer chamber is designed to accommodate two spools weighing 1 kg each or one large spool weighing 2–3 kg. Thanks to a 250 W PTC heater, the device reaches a working temperature of 70 °C in just 15 minutes, effectively removing accumulated moisture from most popular materials.
Design Features and Parameters of SUNLU FilaDryer SP2
- Modular System: The heating platform and drying chamber are separate, allowing multiple chambers to be freely stacked for workspace optimization.
- Fast and Even Heating: A 250 W PTC heater ensures the chamber heats up to 70 °C in just 15 minutes for effective material drying.
- High Capacity: The internal space volume accommodates 2 spools of 1 kg each or 1 spool of 2–3 kg (spool diameter up to 250 mm, width up to 153 mm).
- Flexible Compatibility: Supports filament diameters of 1.75 mm and 2.85 mm on plastic and cardboard spools weighing from 0.25 to 3 kg.
- Hermetic Thermal Insulation: Silicone seals on the lid and legs ensure excellent heat retention and protection against external moisture penetration.
- Microclimate Control: A built-in digital humidity sensor (hygrometer) with autonomous battery power allows real-time monitoring of humidity levels inside the chamber.
- Triple Safety Protection: A PTC heater with a roller fan with a metal impeller, dual hardware thermal protection, and intelligent software control prevent overheating.
- Ergonomic Design: Convenient handles and recesses in the base facilitate transportation, while double-sided outlets with Air Lock clamps adapt to different 3D printer placements.
Compatible Materials and Versatility
Horizontal axis mounting and filament outlet holes with Air Lock clamps allow printing directly from the dryer.
- Supported Plastic Types: PLA, ABS, PETG, TPU, PVA, Nylon (PA), PC, and other engineering materials.
- Compatible Filament Standards: Diameters of 1.75 mm and 2.85 mm.
