Unnecessary support structures CURA

Recommended Posts

Posted · Unnecessary support structures CURA

See picture below for the part that needs to be printed. Build orientation cannot be changed.

Unnecessary supports are marked with red. Anyone who knows how to get rid of these supports? Support overhang angle is set at 55.

Probably CURA adds them because of the fillets that are used (they create a '90 degree' overhang).

 

Rather not use the 'support blocker' because it costs me a lot of time to add manually.

 

Many thanks in advance

I think you could get rid of those by playing with the Support Horizontal Expansion setting.

Other than this, which is spot on, you may also want to play a bit with the overhang angle. I am not aware of what printer you are using, but on my UM3 and S5, I can get away with up to 65° angle with no issues.

Great, was looking for this option!

However, I won't get rid of the last pieces of support at these places.. 

 

Is there a function in CURA that say: print bridges/overhangs smaller than X mm (for instance 1-5mm) without support?

There isn't one such setting as far as I know. You'll have to play with the settings in the Support menu. And maybe put in some support blocker for those last bits of support if they are really annoying or damaging for you.

 

Make sure that you have all the settings visible by going to Preferences > Configure Cura > Settings and click on the small box next to 'Check All' until there's a tick mark in it. That way you'll have all the settings visible on the Print Setup window. It can be a bit overwhelming at first, but you find your way soon enough.
