Support Blocker


Recommended Posts

Posted · Support Blocker



I would like to remove unnecessary support structure on the outer shell of an object. 

I created a model to use as a support blocker. But it dosen't remove any support. It's only working when I remove the support structure under the model. 

Is there no way to remove unnecessary support just on the outer shell?

    Hey @HFJuli


    I think I figured it out! These are the settings that I changed;

    Your Support Horizontal Expansion was so high that it was generated on top of the model aswell. 
    This should work Mari_CFFFP_Support Blocker.3mf


    Be careful with your raft, we have a known issue where somehow if there is support on top of your raft and you have a primetower, your two initial layers with build material will be skipped. We plan to resovle this issue soon. You can follow the progress here: https://github.com/Ultimaker/Cura/issues/13713

    Hope this helps! Good luck with your printjob.

    Hi @MariMakes


    Thank you. But that's not what I am looking for. I would like to use a second model as support blocker.

    That I don't have to reduce the xy expension.

    Hey @HFJuli,


    A Support Blocker will tell Cura to ignore overhangs, defined in red. But they won't give you the customizability you are looking for. 



    You can also consider turning it around. Instead of using meshes to define where you don't want support you can also use meshes to define where you do want support when you define them as Print as support. That's what is happening in the custom support plug-in from 5axis.


    Is that what you are looking for?

      • 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.
