What to Reduce Ringing in Prints by Adding a Groove and Aligning the Z-seam A Simple Way to Minimize Ringing on 3D Prints Ring reduction is achieved by introducing a small groove into a model, then aligning the Z-seam with it. How to Implement this Technique Start by loading an STL file into a slicing software like Cura. Verify that walls are printed in a counter-clockwise direction, which is typically the default setting in Cura. Adjust the Z-seam settings according to these steps: Set Z-seam settings to "User specified." Check the box next to "Z-seam relative." Enter -1 or any value within the model's diameter for Z-seam Y. Values outside the diameter also work, but results may not be optimal. Note: You might need to swap X and Y, or remove the minus sign, depending on your printer's axis configuration. Increase speed settings to a level where ringing is evident, such as an outer wall speed of 35mm/s and a jerk of 15. Print using a shiny filament for best results. Results Editing the groove depth and angle in Fusion 360 can lead to even better outcomes. Share your findings by posting a Make and specifying the groove depth and angle you used. Perhaps slicer developers could incorporate a "Start and stop point inset" feature to simplify this process. Videos Demonstrating Ring Reduction Techniques
