PrintDry Filament Dryer PRO4

The PrintDry Filament Dryer PRO4 is a high-performance filament drying solution designed to remove moisture from 3D printing materials and keep them dry during printing. With temperatures up to 85°C, it is suitable for both everyday and moisture-sensitive engineering filaments, including PLA, PETG, ABS, TPU, Nylon, PC and composite materials.

The upgraded PRO4 features real-time humidity monitoring, a larger PTC heater and improved temperature control for faster and more consistent drying.

Key Features

• 6 temperature settings: 35°C, 45°C, 55°C, 65°C, 75°C and 85°C
• Real-time humidity monitoring: displays from <15% to 99% RH
• Up to 48-hour timer with automatic shut-off
• Dry while printing – feed filament directly from the dryer
• Holds up to two standard filament spools
• Larger PTC heater for improved heating performance
• Expandable with optional additional chambers
• Optional Large Spool Kit supports spools up to 5 kg / 300 mm diameter
