small toothed belts

A timing belt is a reinforced rubber band with teeth that link the crankshaft to the camshaft, ensuring synchronized rotation. Meanwhile, a timing chain serves a similar function but is made of metal links, providing a more durable solution. Both components are responsible for the timing of the engine's valves, which must be in sync with the movement of the pistons. The rotation of these components is influenced by the engine's operation, and any delay or dissonance can lead to catastrophic engine failure.

A timing belt is a critical component in many mechanical systems, including 3D printers. It is a looped band made of high-strength rubber or polyurethane, often reinforced with materials such as fiberglass or steel to enhance durability and performance. Timing belts are designed to synchronize the rotation of two or more shafts, enabling precise control of movement. In the context of 3D printers, they are primarily utilized in Cartesian, CoreXY, and Delta printer designs to control the movement of the print head and the build platform.
