Custom Shaped Hollowing
Hi all. A friend and I were discussing possibilities and we were wondering if anyone had ever tried printing a 3D model with a custom shaped insert. We're printing in translucent UV sensitive resin on a Photon S. What we were thinking was having a 'blood diamond' in red resin, but we'd like to have a hollow inside of it shaped like a skull, so that you can rotate the model around and see the cavity. Does anyone know if this is possible and/or who might be making such models?

pretty easy in openscad.
You'd just remove the skull model from the interior of the diamond.
Most cad packages should let you do this.
Cool idea too :-)

in openscad it would be a difference operation:
this is using a skull model I already had on my harddrive.
It won't look like much until you run it through a slicer :-)
here's the script:
$fn=12;
difference(){
translate([0,0,18])sphere(d=55);
translate([-20,-18,1])resize([40,40,40])import("c:/skull.stl");
} // end diff
Of course it helps to have a few skull models on the root of your harddrive :-)
I use them to make hinged moulds and then i use the clay skulls as slinging ammunition :-)
heres what you've got:
But in the rendered version the faceted sphere is solid and the skull has been removed from it's interior to leave a skull shaped void :-)

And now I'm thinking: 'I;ve got a bunch of clear filament, this could be easily made to fit on an led tealight :-)
Watch this space lol
Printing time- Is this right?
