I often wondered why the software for generating toolpaths for 3D printing were really only 2D (Moving X & Y axes simultaneously to complete a layer, then move the Z axis to go to the next layer). The Gcode generators for CNC routers can code for simultaneous movement of all axes.

Perhaps there is an historical reason - 2D coding might have been easier to do for the first experimenters and since it was found to work, no one bothered to explore control software anymore.

If Topolabs has developed a generator for multi-axis movement, then it will be a major advance in 3D printing.
