No need to be scared! 3D printing ghosting or ringing is nothing to fear. Check out this quick guide for easy fixes to prevent it.<\/p>\n

Ringing, also known as ghosting or rippling, is a 3D print quality issue that can hurt the visual appearance of a model. You can usually spot ringing on a print if you notice that a part\u2019s exterior walls look rippled, wavy, or just not smooth. Ringing can also cause dull edges and corners on prints, such as when including text on prints.<\/p>\n

This visually destructive print quality problem occurs on 3D prints when the nozzle is prevented from laying down material in a controlled manner, creating a constantly shifting print environment. The ripple effect on the sides of prints is the result of the vibrations in layers, too high a printing speed, and a displacement in the printing area.<\/p>\n

It\u2019s important to understand the difference between ringing and\u00a0layer shifting<\/a>, as they are easily confused. Layer shifting usually results in a printed model that shifts in the same direction after every layer, while ringing causes layers to shift in multiple directions, back-and-forth. Also worth mentioning is the difference between ringing and visible infill; the latter occurs when your wall thickness is too thin and allows your infill to bleed through the model.<\/p>\n

Now that we know what ringing is (and what it\u2019s not), let\u2019s go over three main solutions to ringing, with some other tips to try if the issue persists.<\/p>\n

Solution #1: Tighten Your Belts<\/h3>\n

Your printer likely uses belts to move a component (or multiple), such as the printhead and print bed. Over time, these belts can stretch or the pulleys that hold them can loosen, allowing slack to get into the belt loop. When this happens, the printhead (or whichever component uses belts) will move around during printing, causing ringing in prints.<\/p>\n

To solve this, you can tighten your printer\u2019s belts. The process varies depending on the printer model, but it usually involves tightening a screw on the pulley to pull the belt taut. A good rule of thumb is to tighten your machine\u2019s belts until you can flick one with your finger and it barely bounces, but don\u2019t tighten them too much, as this can decrease their longevity.<\/p>\n

Some machines, like the Ender 3 V2, also have integrated belt tensioners with thumb screws that allow you to easily adjust the belt tension. If your printer doesn\u2019t have these, there are\u00a03D printable upgrades<\/a>.<\/p>\n

Solution #2: Slow It Down<\/h3>\n

The faster your print speed, the faster your printhead will move and the more vibrations the nozzle will experience during printing. There will also be quicker direction changes, which can exacerbate ringing on your print. For these reasons, our next solution for ringing is to print more slowly, which you can do by adjusting the speed settings in your\u00a0slicer<\/a>.<\/p>\n

It\u2019s important to mention that you shouldn\u2019t be lowering your default print speed (around 60 mm\/s for PLA) by more than about 25%. If significant reductions in your print speed don\u2019t solve ghosting, then chances are your speed isn\u2019t the cause. If you think that changing the speed is the right solution, though, print\u00a0a test model<\/a>\u00a0a few times, starting at your current speed and reducing it in increments of 5 mm\/s until surface quality improves.<\/p>\n

Solution #3: Find a Solid Base<\/h3>\n

One of the best ways to reduce vibrations is to print on a solid and steady base. Ideally, you want to place your printer on a stable, flat surface, like a level table, where vibrations will be minimized because components will be secure and won\u2019t shake.<\/p>\n

Using an additional form of vibration dampener can further help reduce ringing\u2019s impact on your prints. Nowadays, most printers also come with pre-installed rubber feet that help make the printer remain stable on the ground (or wherever it\u2019s placed). If your machine didn\u2019t come with rubber feet, you can also DIY some or purchase a couple.<\/p>\n

Other Solutions<\/h3>\n
