- Easily adjust the temperature with 6 presets (35ºC, 45ºC, 55ºC, 65ºC, 75ºC, and 85ºC).
- Built-in timer with a maximum time of 48 hours.
- Real-Time Humidity Monitoring (showing <15% to 99%)
Now with Real-Time Humidity Monitoring
See the humidity drop in real time as the dryer works. Our upgraded filament dryer now comes with a real-time humidity sensor, letting you see exactly how your filament is drying. During our tests, the chamber humidity drops from over 60% to below 15% in just under FIVE minutes, giving you the instant feedback and confidence.


Larger PTC Heater than PRO3

A larger PTC heating unit delivers stronger and more consistent heating, helping the dryer reach target temperatures faster and maintaining stable drying conditions.
New Heating Control Algorithm
Our upgraded heating control algorithm improves temperature stability while reducing thermal stress on the heating system, helping extend the lifespan of the PTC heater.

Dryer Temperature Measurement
PrintDry dryer is regulating its temperature by using a close-loop design. When the temperature is above the preset value, the heating unit will be turned off. On the other hand, if the temperature is below the preset value, the heating unit will be turned on. Therefore, the heating unit always have its ON/OFF cycle. When checking the dryer temperature, the following equipment and method are used.
Device: PH-1016U Multi-channel Temperature Measurement Device with T, J, K Type Thermocouples, 0.1℃ temperature resolution and 0.5℃ temperature accuracy.
Temperatures are measured at 4 locations -- 3 locations inside a dryer and 1 location outside the dryer.
- T1: measured at the hot air outlet (close to the dryer temperature sensor) as shown in the picture below.
- T2: measured in the center half way in the height.
- T3: measured in the center about 50mm below the lid internal surface.
- T4: room temperature.


Spool Adapter included
- 2 metal shafts
- 4 big spool adapters
- 4 small spool adapters
