Advantages of a timing belt driven Z-axis:
Most 3D printer systems use a lead screw or a threaded rod as drive for the Z-axis. Backlash and imbalance cause errors in X- and Y-direction when moving the Z-axis. These errors are visible as vertical pattern on the printed object.
When using two timing belts as attachment for the Z-axis these errors can cleverly be avoided. Consequently the Z-axis is nearly error free, thus the layers of a printed object lie perfectly on top of each other.
