SUNLU and INSLOGIC Launch the FilaDC i10: Filament Storage That Actually Solves Humidity

Damp filament is one of the most consistent causes of bad FDM prints. Hygroscopic materials such as PA, PETG, and TPU pull moisture from the air, and that moisture shows up as popping during extrusion, stringing, weak layer adhesion, and rough surface finish. The usual answer is a heated dryer. Dryers work for reconditioning a spool before a print, but they are not ideal for long-term storage. Prolonged heat can soften spools or warp the filament itself. A dried spool returned to an open shelf starts reabsorbing moisture almost immediately, and that is the problem the new FilaDC i10 from SUNLU and INSLOGIC is designed to solve.

How the Dehumidification Works

The i10 uses a molecular sieve desiccant system that runs at room temperature. Air inside the cabinet circulates continuously through the desiccant, which captures moisture without heating the filament. When the sieve saturates, the unit automatically heats the desiccant bed to release the trapped water, then returns to absorption mode. High-precision humidity sensors inside the cabinet monitor conditions in real time and tell the system when to switch between adsorption and regeneration.

The target humidity is user-adjustable between 10% and 55% RH with an accuracy of plus or minus 5%. The product documentation recommends 10-25% RH for standard 3D printing filaments, 25-30% for pharmaceutical raw materials, 30-40% for electronics and semiconductors, and 40-50% for optical instruments. That flexibility makes the unit useful for print farms, makerspaces, and small labs that need to store more than just spools.

Capacity and Operating Details

The internal dimensions measure 385 x 258 x 488 mm, and the two-tier interior holds up to ten 1kg spools. The unit accepts a range of spool sizes up to 200 x 67 mm, which covers the formats used by most major filament brands. It runs at or below 35 dB, so placement near a desk is practical, and its surface temperature stays under 30 degrees Celsius during operation. The cabinet is stackable, so scaling to cover a larger material library is straightforward.

Power draw is modest. Dehumidification mode uses 1W, standby is below 0.2W, and baking mode, used during desiccant regeneration, draws 100W. The unit accepts either AC 110V or 220V and carries RoHS, FCC, and CE certifications. It includes a one-year warranty.

Pre-orders and Pricing

Pre-orders open on September 15, 2026 at 7:00 AM UTC via the SUNLU online store. An Early Access Pass costing $1 is available until September 14 and guarantees the lowest launch price plus a $10 discount code at checkout. The official pre-order price has not been announced yet. Pre-orders are open to customers in the United States, European Union, United Kingdom, Canada, and Australia.

The Practical Case for the FilaDC i10

Heated dryers are effective tools, but they treat filament as something to condition before printing rather than something to store continuously. The i10 approach is different: filament stays in the cabinet between jobs and comes out ready to use without any pre-drying step. For anyone running multiple material types, maintaining discipline around re-sealing open spools after each session, or managing a print farm where dozens of spools are in active rotation, that difference matters.

The room-temperature operation also removes the concern about heat-sensitive materials such as TPU, PVA, and some engineering filaments that can deform or lose properties at elevated temperatures. If the cabinet holds the stated humidity range consistently, the FilaDC i10 could replace both a filament storage solution and a long-term dryer for many users.
