Printing without print head fan?


Recommended Posts

Posted · Printing without print head fan?



Ultimaker 2+. What are the consequences of printing without the print head fan for a few days? The middle smaller fan, not the sides ones. I need to finish a project in a few days and a replacement would only arrive next week.


The fan in question is Sunon Maglev MC25060V1-000U-A99. Are there any other alternatives or is this the one and only I need to purchase?


Thank you.

    Print failure, Jamming, heat creep, physical damage of the print head.. possibly more issues.

    Unfortunately the small middle fan is the most important fan. It keeps the cold side of the print head cool.
    I would not recommend using that printer at all until the fan is replaced.

    Also I wouldn't advise trying to source a "cheaper alternative" for the fan as the cheaper ones usually have lower air pressure.. using an under powered fan will usually result in the same issues as not having one at all.

        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
