3D Printer Motion & Bearing

In most 3D printers the build platform (including the extruder) slides over smooth rods as it moves. The polished rods support the components and guide the motion of the extruder along a linear path. Bearings or bushings are used on the straight steel rods to create motion that is smooth and jerk free where the extruder is moving in a single direction.Among 3D printer enthusiasts, bearing and bushing options are available, including bushings of various materials, and linear bearings, which tend to be made of bronze and have rows of ball bearings located on the inside.Which look like tubes and can be made from bronze or from polymers. Both types attempt to achieve a reduction in power, noise and wear.
