One can use OpenSCAD to slice a 3D STL or an object made in OpenSCAD into SVG usable with the Lasersaur.
Example of a CSG object
Example of a sphere on top of a cube (thing() in below code) which is sliced; and each slice is then laid out flat.
module thing() {
difference() {
union() {
translate([-5,-5,0])
cube([10,10,10]);
translate([0,0,12])
sphere(r=10);
};
union() {
translate([-5,-5,0])
translate([1,1,1]) cube([8,8,8]);
translate([0,0,12])
sphere(r=9);
};
};
}
z_min = 0;
z_max = 23;
slice = 1;
n = 5; // floor(sqrt((z_max - z_min)/slice+10));
for(z = [-z_max:slice:z_min]) {
i = (z + z_max) / slice;
x = 40 * (i % n);
y = 40 * floor(i / n);
translate([x,y,0]) {
projection(cut=true)
translate([0,0,z]) thing();
};
};
Example with an STL
An example of an STL that is loaded from a file and then sliced. You will have to manually adjust the Z range & slice distance.
