Printing with the Air Manager

The Air Manager is supported by Ultimaker S5 firmware 5.4.23 and later. Three parameters influence how the Air Manager works:

  • Build volume temperature
  • Build plate temperature
  • Ambient temperature

When printing with Ultimaker materials, the build volume temperature is preset by the material profile.

Build volume temperature

The Air Manager maintains the internal temperature of the printer at the desired Build Volume Temperature. The Build Volume Temperature is a setting within Ultimaker Cura.

Quickly find the build volume temperature setting with the search function. For the best results, always use the latest version of Ultimaker Cura.

The Air Manager adjusts the fan speed to maintain the specified chamber temperature. The fan speed is calculated dependent on the build plate temperature as well as the ambient temperature, measured by the Air Manager’s own temperature sensor.

Note: When slicing using an older version of Ultimaker Cura, or any other slicer which does not have a value for the build volume temperature, the Air Manager will default to 100% fan speed.

Note: The build volume temperature has a maximum value of 50 °C to prevent damage to the printer.

Air Manager operation

Any time a print core or the heated bed exceeds a temperature of 50 °C, the fan of the Air Manager will turn on. At these temperatures, residual material on the build plate or in the print cores can emit UFPs, which should be filtered. Therefore, it is normal for the fan to spin during other operations that require heating, and not only during printing.  

After finishing a print, the Air Manager will continue working until both print cores and the build plate have cooled down to below 50 °C. This ensures that the filter captures all residual UFPs in the chamber. When a print has finished, wait until the printer has completely cooled down and the fan has stopped spinning before opening the doors to remove the print.

Caution: Ensure there is at least 10 cm of free space at the back of the Air Manager for unrestricted airflow.

The filter

The Air Manager uses an E10 filter. The lifespan of this filter is 1500 hours and the Ultimaker S5 tracks the usage time of this filter. There are three filter states:

Filter state

Shown when
Peak performance

Filter usage < 90% lifespan 

(up to 1350 hours)

Replacement near

Filter usage is between 90% and 100% lifespan

(between 1350 and 1500 hours)

Replacement advised

Filter usage > 100% lifespan

(above 1500 hours)


Furthermore, the Ultimaker S5 Pro Bundle can detect whether a filter is present or not.  

To replace the filter, use the filter replacement wizard found in the maintenance section of the printer. Using the wizard will reset the filter lifetime counter back to zero.

Tip: The filter hours can also be manually be set back to 0 using the Reset option if the filter was replaced without using the replacement wizard.
