5. Sunlu Fila Dryer SP2

Modular and space-saving design
The unique "one base, multiple chambers" system of the SP2 allows for vertical stacking of up to three drying chambers – ideal
for print farms or environments with multiple printers. It maximizes capacity while minimizing space requirements.

Fast and precise moisture control
With a reliable heating system that reaches 70 °C in about 15 minutes, the SP2 efficiently dries common filaments like PLA, PETG, TPU, and ABS. Tests show that the moisture content of PETG is reduced from 0.6% to 0.2% in just four hours – about 30% faster than the competition.

Sealed, smart, and quiet
The airtight chamber uses a silicone seal and a triple safety system (200 W PTC heater, fan, temperature shutdown) for safe operation. A built-in hygrometer provides real-time readings, and the device operates quietly at around 59 dB.

Dual function
In addition to drying filaments, the SP2 also serves as a high-quality storage box. It supports various spool configurations and can be used independently. Ergonomic handles make transportation easy, and cable outlets allow for flexible use.
