 To send these four bodies to the slicer at the same time, I'm going to click up here under my browser and go to save as mesh. As long as all these bodies here are visible, it'll go ahead and send it. My application here is going to be the bamboo slicer, bamboo studio, I'll click OK, and Fusion will automatically open up the slicer and throw all the bodies right in. To 3D print these so that the infill shows through, go to your strength tab, take your top shells here to zero and take your bottom shells to zero. Now when you slice it, you'll see that you've got your infill here showing with no top and bottom layers. Now to make this a little bit stronger, we're going to increase our wall loops here. I'll do six and then I'll re-slice those. You can see now we've got a much thicker wall around it. There are much more interesting infill patterns here you can play with. So I'm going to go down to grid here where it says sparse infill pattern and you can do something like octagram spiral and there's all sorts of different ones you can play with.
