STL is an industry standard and is based on triangles, the only good
thing about it is that it is scalable otherwise its big and horrible
to deal with.

The SLC file format was invented by 3D systems for their printers, it
is a layer by layer format which defines the contour boundaries for
each layer and by the order the points in the boundaries are listed
CW/CCW defines if they are internal or external. These files SHOULD
be easy to deal with (if Rhino and others got it right) and are 15 to
20 times smaller for complex geometries than STL.

Exporting any model, STL or whatever from Rhino4 is just a matter of
save as. Then Roger's software converts the contours to bitmaps by
filling them in ready for printing. Nothing lengthy about it and much
quicker than it would be with STL.
