Together with absolute encoders, ballscrews provide identical layer height and accurate overall part's size. Typical layer height is 20-90 micron, in most cases, it will be 50 microns. It is critical to have the very same layer height over the whole printing because it influences the welding process.

C5 is an industrial standard of ballscrews which is precision ground ballscrew, widely used in metalworking machining centres.
