Convince Cura I need more Support?

[cbrinker 0]

I'm trying to print out one of these: http://www.thingiverse.com/thing:139995

The issue is that the way the part is oriented, two of the horns are not steep enough to convince the support algorithm to make towers underneath them (As annotated by the yellow ovals below). To work around this, I have rotated the model many different ways, but I can never seem to convince Cura to make consistent support towers under critical parts. I tried orienting the part os the chin is the only part touching the buildplate, but there is so little surface area that 20 layers in the chin gets ripped off the bed. Is there a button/setting I am missing somewhere to support these horns? Is this part printable with the current Cura-13.12-MacOS?

Thanks,

Chris

I think this is a known bug in Cura. You might consider using Meshmixer 2.0 to add custom support pillars before slicing it.

Increase the xy distance in the expert support settings. Try 1.5mm. Not a perfect solution but it generally works for me.

Maybe if you rotated the head a bit so that those "horns" are steeper?

Or add your own custom support using some cad software.

Or try cua 13.04 which has a totally different support algorithm and slicer:

(it's okay to have 2 versions of cura installed at the same timeO)

 

Or try kisslicer (it's free and has a beautiful gui just like cura).
