Forcing Infill?

[Pridanc 4]

Folks, 

Just built a test model off of a PP model I've been printing and wondered if I could "force" CURA to use infill on (in)  the bottom of the part?  At the moment, CURA puts down 10 layers of material and continues on without any infill.  This in and of itself is all good as it prints but I'd like to use some infill for the bottom of the part? Or is this area too thin?

 

Remember, this is a test so there is no particular rhyme or reason to my settings. 

 

Thanks in advance,  PDC

Can I be the smartarse in the room and say "just add a cube model to the scene, scale it to fit and put it in there?"

But that's alright. We have our own cubes. Use the support blocker tool, click somewhere on your model and it will add a support blocker. Now switch to the move tool, click the support blocker so only it is selected, then move it to the centre and scale it to fit inside your rectangle, up to the height you want.

 

Then we touch the magic "per model settings" button! 

Being a support blocker, it'll start as a "don't support overlaps" type:

If you want to fill the model so it's solid up to a certain height, with infill and then skin on top, just click the first button that turns it into a normal model!

Cura automatically combines models which intersect each other. So now it'll just be a filled in model with infill on the inside and skin layers on top!
