Cut-Away 3d printed model?

[hotponyshoes]

Let's say I am printing rubber horseshoes
All outer surfaces are solid.
I can adjust the softness of the shoe by changing the amount/type of infill.

I want some cut-away models for demonstration purposes with the cut outs on all 3 axis. (Basically, so you cam see through the outer walls and look at the infill from all directions)

The horizontal one is easy as I can just cancel the print before it's finished although that leaves it completely exposed rather than the part cut-away look I am after.

I don't suppose there is an easy slicer setting for something like this?

I can build these cut-out sections into the model but can't seem to figure out how to avoid the slicer printing a wall or roof on them?

If you can't make the slicer do it, can you just model the infill and the section you want and print the part? Maybe print the 'sectioned' ones at 2-300% to make it easier to handle?

Failing that, a milling machine and a brand new cutter?

Hot wire cutter should give you a nice clean slice.

If you can make the build plate plane the plane that cuts the cross section, then you can just reduce the bottom layers to zero in the slicer. Your print will begin at the infill.

So cut your model in cad or the slicer where you want the cross section. Then position that cut to be touching the build plate. Then set bottom/floor layers to zero in the slicer.

Obviously this assumes that your model lends itself to printing in that orientation.

(You can do the same with top layers too if that works better but I’d need to see the model)
