Support inside model

[Feuille 0]

Hello everyone, I'm new to this forum,

 

I was wondering : I'm going to print a model that has big thickness, so if I print it without infill, some parts can't be printed because they are not being supported by anything, you know what I mean ?

 

Anyway, is there an option in cura to only print infill on overhang parts ? Because even if I enable supports, cura don't recognize those parts as overhang parts.

 

It's difficult to explain it like that, tell me if you need more explanation or illustration.

 

Thanks (I'm french and my english is not that good)

Simpler example : imagine you want to print a cube with no infill, at the end of the print, when the printer is "closing" the cube with the "roof", it doesn't have support to print on. That's what I want, having a support only on those overhang parts, not elsewhere.

 

I know I could enable infill, but I want to save filament and infill will be printed everywhere in the model and not only on those overhang parts.

If your main aim is to save on filament used for infill than you could try using the "gradual infill steps" setting, this setting lets you start off with hardly any infill and then as it gets close to a roof it add's more infill based on your settings.

Wonderful ! Thank you Carla !

My model is too geometric so there's no difference :/. Hm.. Can we stop infill at a certain layer ? Because I need it only for the first layers

Nice ! There's a trick to change infill density on specifics parts using the support blocker !

 

Here's the video, I think I solve my problem : https://www.youtube.com/watch?v=su_m5zV9rvA
