Drywise In-Line Filament Dryer
The Drywise in-line filament dryer is designed for professional-grade use in additive manufacturing.
It comes with pre-programmed settings, offering quick and efficient in-line drying by connecting directly to your 3D printer.
- Available in both 1.75 and 2.85 mm versions for maximum compatibility.
Inside the Drywise dryer, hot, dry air circulates, drawing moisture from the filament in the chamber. A desiccant cartridge traps the moisture, re-drying the air, similar to an instant water heater that quickly heats a small volume rather than a full tank that takes longer to warm.

Key features of Drywise
- Speed. Drywise dries only the section of filament needed for printing, minimizing workload.
- Smart. Intelligent sensors monitor and optimize drying conditions, reducing filament degradation and preventing multiple heating cycles.
- User-friendly. Intuitive interface guides users, while replaceable desiccant cartridges help minimize downtime.
- Safe. Smart sensors adapt settings to the filament's movement and condition.
- Upgradeable. Certified filament parameters are continuously updated for optimal drying.
- Versatile. Compatible with a wide range of spool sizes and formats.
High-quality materials are key to successful 3D printing
Many 3D printing materials are hygroscopic, meaning they absorb moisture from the air. Moisture content impacts print quality, so filament should be dried to ensure optimal performance. While drying materials before use is common in injection molding, it is equally crucial for 3D printing filaments.
Over 50% of new filaments require drying before printing. Even newly unsealed filaments often benefit from additional drying, as Drywise research has shown.

Comprehensive quality control for materials
- Significant time savings. Integrated drying architecture enables near-instant drying, while pre-calibrated parameters for certified filaments streamline settings and eliminate guesswork.
- Reduced setup time. In-line drying while printing is more efficient than pre-drying entire spools, saving both time and energy.
- Increased machine uptime. No advance scheduling required, allowing for uninterrupted 3D printing.
- Lower energy costs. Efficient drying reduces the need for additional devices to keep filament dry.
- Minimized material waste. Superior material quality control reduces printing errors.
- Reliable process. Drywise ensures consistent material quality, delivering dependable, high-quality prints every time.
The impact of moisture on 3D printing results
Moisture in filament negatively affects print quality, as shown in the first image below:
- Surface roughness
- Dimensional inaccuracies
- Weakened mechanical properties
- Irregular extrusion flow


Traditional filament drying challenges
Moisture damage incurs hidden costs:
- Lost time. Time is spent on material preparation, parameter testing, and handling.
- Machine downtime. Limited by pre-scheduled drying, reducing operational flexibility.
- Material waste. Poor drying results in low-quality prints with weak aesthetics, leading to wasted materials.
- Process inconsistency. Results vary due to environmental factors and differences in initial moisture content.
- Additional equipment needed. Auxiliary devices are required to maintain filament quality post-drying.
- Material degradation. Multiple heating cycles may degrade the filament if not used immediately.
