CURA Cura 4.12.1 Internal custom support is not printed

[rudolf992 0]

Hello,

 

I am designing a box for my electronic project, and I'm having difficulties placing  custom supports inside the model. In the preview panel the supports that are not touching the base plan are just not printed. Is there a solution? 

 

 

Thank you!

Those are so tiny that they fall below your settings and are ignored.  (That is doubly true for the ones supporting the clip overhangs.)

If you just adjust the Y widths on the tall ones, and make the little ones bigger in both the X and Y, and make an adjustment to the "Per Model" settings (see below) they will slice.

 

And now (since I've put some time into this) I will critique the design.

Those lock tabs ARE going to break off.  The reason is that the layer adhesion won't be strong enough to resist the forces they will see.  Removing the support will also be problematic.  I would suggest you go with #2 sheet metal screws instead.  I know, you have to get a tool to assemble or dis-assemble, but it will work repeatedly whereas the tabs may not work even one time.

The back sides of the tabs have a square bottom and would require support.  If they had a 45° chamfer they would not require support.

 

 

With some adjustments to the support settings - this is the support that Cura provides with no "Custom" support structures.  That would be my preference on this model.  There is the tall skinny support being generated for the backside bottoms of the tab structure.  I think I would use support blockers there as tall skinny support structures often fail.
