Ringing / Ghosting / RipplingUpdated 7 months ago

Ringing, also known as ghosting or rippling, is a common issue in 3D printing where wavy patterns appear on the surface of printed objects. This defect is typically caused by vibrations or wobbling of the printer during sudden direction changes, such as when the extruder moves around sharp corners. The inertia of the extruder during these sudden changes can create vibrations, which become visible on the print itself. Please follow the instructions below to fix this:

Reduce Print Speed

High print speeds can cause excessive vibrations, leading to ringing artifacts. Reducing the printing speed can help minimize these vibrations and improve print quality. Lower the printing speed in your slicer software. Start by reducing the speed by 20% and observe the results. Continue adjusting until the ringing is minimized.

Tighten Belts and Pulleys

Loose belts and pulleys can cause play in the printer's movement, leading to ringing. Ensuring that these components are properly tensioned can significantly reduce vibrations. Check and tighten the belts and pulleys on your 3D printer. Ensure they are taut but not overly tight, as this can cause excessive wear on the components. Properly tensioned belts will reduce vibrations and improve print accuracy.

Optimize Acceleration and Jerk Settings

High acceleration and jerk settings can cause sudden movements that lead to ringing. Adjusting these settings can smooth out movements and reduce vibrations. Adjust the acceleration and jerk settings in your printer's firmware or slicer software. Lowering these settings can smooth out movements and reduce vibrations. Start with small adjustments and test the results, gradually fine-tuning until the ringing is minimized.

Improve Frame Stability

A stable printer frame can help reduce vibrations and ringing. Ensuring that your printer is placed on a stable, level surface can also help. Ensure your printer is placed on a stable, level surface. If possible, use a heavy, solid table to minimize vibrations. Additionally, consider adding bracing or reinforcement to the printer frame to improve its rigidity.
