Support Material Slicing Issue with Cura 4.3


Recommended Posts

Posted (edited) · Support Material Slicing Issue with Cura 4.3

Hi there,


I've got that following issue with cura 4.3 (using Ultimaker S5 Printer)

The model i want to print is standing on 4 feets (as you see in the screenshots below)


Model 1:



Model 2:



Now.. the base of the model which stands on the 4 feets obviously needs to be supported.
Im working with the standard printer settings except the support structure setting, with is set to


Generate Support: YES
Support Extruder: Extruder 2


The first layer of the models base is layer 20. So the last support layer is layer 19.
I expected the layer 19 to be a "full" printed support layer (so that the models base is supported correctly).
What the cura 4.3 slicing output is, is the following screenshots (model color: red).


cura 4.3 layer 19 (what the..?!):



cura 4.3 layer 20 (...can't print on air..):



With cura 4.1 i installed a later version and sliced again with the same settings (pic 5, model color: green)


cura 4.1 layer 19:



So .. is this a known issue? Are there any mistakes i did?

    Hi everyone,



    - the problem reacts to the setting "Support Horizontal Expansion"


    If i slice my acutal file with the following settings, i get the following results

    0   =>   no print on air

    1   =>   print on air

    2   =>   print on air

    3 (default)   =>   no print on air


    For my initial post, i'm 100% sure that i used the default settings

    For my last post on feb.27 im not sure about the "Support Horizontal Expansion" setting


    So now that i described the problem and even served a possible solution, i hope for some more reaction.


    will keep you updated...
