My 3D printer is creating 'ringing' or 'ghosting' artifacts. What is this and how can I fix it?

Ringing, also known as ghosting or ghost artifacts, appears as repeating wave-like patterns on the surface of a 3D print, usually following sharp corners or features. This is a result of vibrations within the printer's frame or motion system. To reduce ringing, lower the print speed and acceleration settings in your slicer. Ensuring the printer is on a stable surface and that its frame is rigid can also significantly improve print quality.
