My background is predominately in CNC machine. I know regarding CNC machines that professional machines don't use rubber belts of any kind, basically because of all the issues around the belts themselves. Instead they use Ballscrew Linear Rails because they have much less friction and work much better.

I tried to find a 3D printer that used Ballscrew Linear Rails but I couldn't locate any. Is there a reason for that (other than cost)?

Does anyone have any information (good or bad) regarding adding Ballscrew Linear Rails to a 3D printer?
