- Capacity: Holds up to 10 × 1 kg spools (0.25 kg – 5 kg each); stackable up to three units.
- Power & noise: 0.23 kWh per 24 h; ≤30 dB sound level – quiet enough for home or workshop use.
- Safety: Dual hardware temperature protection plus software‑driven monitoring.
SUNLU & INSLOGIC Unveil the FilaDC i10 Filament Dehumidifying Cabinet
SUNLU and INSLOGIC have teamed up to launch the FilaDC i10, a purpose‑built cabinet that safeguards 3D‑printing filament from moisture between jobs. The device targets the chronic problem of hygroscopic filament degradation without the energy waste of constant high‑temperature drying.
How the i10 Works: Physical Adsorption + Smart Cycling
The heart of the i10 is a molecular‑sieve cartridge that adsorbs water molecules from the internal air. Unlike passive desiccant packs, the i10’s smart‑cycle system periodically heats the sieve just enough to release the captured moisture and restore its adsorption capacity. This closed‑loop process keeps the chamber’s relative humidity (RH) between 10 % and 45 %, even when ambient conditions fluctuate.
Performance snapshot – a 96‑hour test on PETG filament showed:
| Condition | Initial moisture (wt %) | After 96 h (wt %) |
|---|---|---|
| Inside i10 | 0.34 | 0.21 |
| Exposed to open air | 0.35 | 0.39 |
The i10 therefore reduces moisture by 38 % versus ambient exposure, delivering a stable environment that eliminates the need for continuous oven‑drying.
Capacity & Form Factor: 10‑Spool, Stackable Design
- Spool slots: 10 × 1 kg (compatible with 0.25 kg – 5 kg spools).
- Sealing: Integrated gasket and three neodymium magnets ensure a tight closure.
- Stackability: Up to three cabinets can be safely stacked, saving floor space in busy studios.
The cabinet’s footprint (≈ 350 mm × 400 mm × 200 mm) fits on a typical workbench while still offering ample storage for a small to medium filament library.
Power Consumption & Acoustic Profile
Operating at 0.23 kWh per 24 h (tested at 25 °C, 60 % RH in an empty chamber), the i10 draws less power than most filament ovens, which typically consume 0.5 – 1.0 kWh per day. Its fan and control electronics stay under 30 dB, making it virtually silent in a home office or classroom.
Safety & Reliability
Long‑term operation is protected by:
| Protection Layer | Function |
|---|---|
| Hardware temperature sensor | Shuts down heating element if internal temp exceeds safe limits (≈ 55 °C). |
| Software watchdog | Monitors cycle timing, humidity, and power draw; triggers alerts via the companion app. |
| Over‑current fuse | Prevents electrical overloads. |
These safeguards reduce the risk of fire or filament damage during unattended use.
How the i10 Stacks Up Against Conventional Drying Solutions
| Feature | FilaDC i10 Cabinet | Typical Filament Oven | Desiccant‑Bag Storage |
|---|---|---|---|
| Humidity range | 10 %–45 % RH (active control) | 30 %–70 % RH (passive) | 30 %–80 % RH (passive) |
| Power draw | 0.23 kWh/24 h | 0.5 – 1.0 kWh/24 h | <0.05 kWh/24 h (no heat) |
| Noise | ≤30 dB | 45 dB‑60 dB (fan) | Silent |
| Capacity | 10 × 1 kg spools | 4 – 6 × 1 kg spools (size‑dependent) | Variable, limited by bag volume |
| Automation | Smart‑cycle regeneration | Manual timer or continuous heat | Manual replacement of desiccant |
| Safety | Dual hardware/software monitoring | Basic thermal cut‑off | No active heating – inherently safe |
The table highlights the i10’s blend of low energy use, precise humidity control, and hands‑free operation—advantages that most ovens and simple desiccant bags cannot match.
Bottom Line
SUNLU’s partnership with INSLOGIC yields a compact, energy‑efficient filament dehumidifier that bridges the gap between passive storage and power‑hungry ovens. By leveraging molecular‑sieve adsorption with an automatic regeneration cycle, the FilaDC i10 delivers consistent 10 %–45 % RH, reduces filament moisture by nearly 40 % in 96 hours, and does so quietly while consuming less than a quarter kilowatt‑hour per day. Its 10‑spool capacity, stackable chassis, and layered safety systems make it a practical addition to any serious 3D‑printing workflow, from hobbyist benches to professional print farms.
