If you want to do this regularly get a slicer like Simplify3D. It's not free, but it's not expensive and it's awesome. You can change every single parameter based on layer ranges. Not sure if slic3r has this ability but if slic3r had this and supports as good as S3D I'd just use slic3r.

Edit: someone beat me to it. It's a good tool to have in your arsenal. Strongly consider it.

Perhaps :-)) i still awaiting the press, so its all new to me...

Another idea could be... just add solid boxes around the area that you want to reinforce?
I mean, straight INSIDE the original model.
Surely not high class involved in the solution, but very quick and effective

I have tried dif infil patterns and change percentage infil. found best strength from Honeycomb flow set half as thin as perimeters and spacing about 2x perm then 30% fill max 70% very solid. its like spokes or aircraft frames. also lay object flat on side needing most linear strength in horizontal plane when printing. also support material can be thinned same way to ease removal

Not specifically in different portions of the object, but in Simplify3D you can add several processes to objects.

for example layer 0-100 10% infill+ 1 perimeter, layer 101-200 100% infill +2 perimeters, layer 201 to end+5 perimeters etc..
processes can control everything, so you can have printspeed, layerthickness, temps etc different in several parts of the object.

But no left,right etc parts.. just in z.

I've thought about this before - selecting and changing the infill density for different regions of a part. This would certainly be an appreciated feature in my book. Hopefully someone around Slic3r or Simplify3D is listening...

It's a large part of the fun & sense of achievement, a well-designed part that prints well and works with minimal finishing!

You can make a hole that is very tiny, like .5mm. It will never manage to print an open hole that small, but it will do a bunch of perimeters around it creating a solid spot among the infill. You could distribute those holes around areas that might need to be stronger. They don't even need to pass all the way through the object, they could be in the middle, creating a solid pocket with infill above or below.

+1 Cool tip, thanks Ian!

Thats infill settings. 100%=solid object
Play with that.

Preview layers to see the effect before you print.

Ohh, its is not in SketchUp i meen(i am just usint it),, the object is made, but then i slice it, i can see honnycone grit , but if i wantet a piece of the object filled up abd the rest whit gitter, how doe one do that, can i set it in ths slicer or do the object have to be design to that situation.

No offense but throw away sketchup and get blender

How can you create areas that are completely covered in an object where a screw should go through and have only honnig grid places where strength should be less, I use Sketcup ...
