SUNLU and INSLOGIC's FilaDC i10 Dries Filament by Removing Moisture From the Air

Damp filament is one of those problems that sounds small until you hear it. A spool that has been sitting out for a week starts popping during extrusion. Stringing appears. Layer adhesion drops. The surface finish gets blotchy. Most makers reach for a heated dryer, dry the spool for a few hours, and then put it back on the shelf where it immediately starts absorbing moisture again.

SUNLU and INSLOGIC think there is a better way. Their new FilaDC i10 is not a dryer. It is a dehumidifying cabinet that keeps the air around the filament dry continuously, so the spool is ready when you are.

How It Works

The i10 circulates air inside the chamber through a bed of molecular sieves. These sieves trap moisture from the air. When the sieve gets close to saturation, a PTC heating element drives the trapped water out of the unit. The assembly then cools and goes back to absorbing. A small touch display shows the cycle status: absorbing, exhausting, or cooling.

There is no consumable desiccant pack to replace. The cabinet does not heat or humidify the spools themselves. It simply keeps the surrounding air at a set humidity level. That matters for people who run PETG, nylon, or TPU regularly, because those materials pull water out of the air almost as fast as a heated dryer can push it out.

The Specs

The FilaDC i10 measures 395 mm x 300 mm x 508 mm on the outside and holds ten spools on two shelves. Each spool can be up to 200 mm in diameter and 67 mm wide. The humidity setpoint runs from 10% to 45% RH. SUNLU and INSLOGIC rate noise at 30 dB or below, external surface temperature at 30 C or below, and power consumption at 0.23 kWh per 24 hours. For comparison, a typical 200 W heated dry box consumes 2.88 kWh per day.

The unit accepts AC 110 V 60 Hz or 220 V 50 Hz. Input power is 1 W during dehumidification, 100 W during sieve regeneration, and 0.2 W or less in standby. The cabinet comes with a one-year warranty and is designed to stack, though SUNLU warns against putting heavy objects on top.

What It Means

The FilaDC i10 is not a replacement for an active dryer on a soaked spool. If your filament has already absorbed significant moisture, you still need heat to drive it out. Where the i10 fits is between prints: a low-energy, quiet place to store spools so they do not reabsorb water the moment you stop watching them.

For anyone running a print farm, a workshop with seasonal humidity swings, or just a corner of the garage that gets damp in winter, that is a genuine gap in the typical setup. Heated dryers are loud, power-hungry, and temporary. A sealed cabinet that passively maintains dry air is closer to how professional moisture-sensitive storage actually works.

The FilaDC i10 pre-order is scheduled to open on September 15, 2026 at 7:00 AM UTC.
