Bad news, SDFs are not useful for slicing models for #3dprinting .
The idea: render every slice and get a nice picture with distances from walls already marked, then place filament on those ridges.
This needs some adjustments. A floor is equidistant from the 3d edge, but not slice edge:
float sdSphere23(vec3 p, float r) {
float u = asin(p.z / r);
return length(p.xy)/sqrt(1. - u*u) - r;
}
...but this still fails if you want to rotate anything.
A picture of concentric rings. Imagine the yellow ring is the object outline, and the reddish in the middle are where the filament goes.
Rotated around the X axis (in screen plane), the circle is bent, what was rings makes it look like a watermelon.
