UM3 Hot end cooling fan broken blade

Posted (edited) · UM3 Hot end cooling fan broken blade

Hey guys,

I've been doing a lot of printing on my ultimaker 3.  I've been doing ABS almost exclusively, doing a lot of printing with HIPS as a support material and it's been working great.

However, I realized yesterday that one of my prints was extremely brittle, almost burnt looking at the very end of the print.  If i pushed on the small parts with my finger they would crumble.  I tried to print again with a different roll of filament since this was my first print after putting a new roll of Inland filament on, but it failed about an hour or two into the print this time instead of at the end.

After scratching my head for a while trying to fix a clogged nozzle, etc. I looked straight at the hotend and saw that a blade of the cooling fan had broken off and was wedged in between the fan and the plastic fan guard so it would not spin.  I got the blade out with a tweezer but now the fan vibrates quite a bit since it's off balance.

Long story short, I need to find a place to get a replacement hot end fan for an Ultimaker 3.  I'm contacting support as I write this post to see where that gets me.   I've also attached pictures of the crunchy pieces as well as the fan blade for reference.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
