making a hollow box

I want to print a project box for electronics. It is hollow in the center. The walls are about 1.5mm (I forgot the exact measurements right now). I was reading in the document that one can control how many layers are solid before the printer starts a partial-fill pattern. I see the outer perimeter shell feature in the machine controls. Since this is a hollow box, and not a solid, how do I make sure there is 100% fill? Do I just specify enough layers of shell to exceed the thickness of the wall? Do I turn the partial-fill mode off? Again, I want the walls and floor to be 100% filled in.

thanks.

Re: making a hollow box

if you want everything to be 100% solid besides say the top or the front, just make sure it is modeled correctly (basically a cube with one open side and then nothing in the middle), then set the infill to 100%. This will make all aspects of the model 100% solid

Re: making a hollow box

thank you. That makes sense.

The walls and floor are 1.75mm thick. Would a layer 0.25mm be appropriate? Would the quality be reasonable? Would it be better to make the layers 0.175mm and have 10 "shells" for the thickness?

Re: making a hollow box

the layer height just refers to how high the z axis moves per layer. meaning every layer will be .25mm high, just do 2 shells and 100% infill, look at the gcode previewer after you slice, the object will be 100% solid.

Re: making a hollow box

So the 0.25mm is the height of each layer as you said. What controls the thickness of each shell? What, for that matter, controls the resolution of the X and Y dimensions?
