Test for Ghostingĭownload this Ghosting Test from Thingiverse to find out whether you are experiencing ghosting. When you use a 3D printer which has good rigidity, it can deaden the vibrations effectively. These are less rigid and so are more prone to vibration from the moments of inertia. The occurrence of ghosting will be more prominent with 3D printers that have a cantilever design such as the one in the video below: These type of imperfections are sometimes referred to as ‘artifacts’.Īs we know, 3D printers have to be precise in the way they build up an object layer by layer, so this resonance caused by quick movements can have the effect of creating inaccuracies in your prints. If intense enough, the vibrations are likely to leave you with imperfections on your prints, ghosting. When there are quick directional changes with your 3D printer, these movements can cause bends and flexes in the frame. Your extruder, metal parts, fans and all sorts can get heavy, and coupled with the fast movements result in something called moments of inertia.ĭifferent combinations of movements, speeds and directional change, with the weight of your printer’s components can result in ‘loose movements’.
Resonant frequencies from quick movements.
Precise details such as wording or logos.
When 3D printing, your machine moves large objects at a fairly high speed. Ghosting is caused by something called resonance (vibrations). The causes of ghosting are pretty well known so I’ll explain it as simply as I can. It’s especially prominent in prints that have wording engraved, or a logo embossed into it. So some areas of your prints look perfect, while others look bad. Ghosting sometimes can only affect certain parts of your prints. Ghosting is also known as ringing, echoing, rippling, shadow and waves. You are likely to be seeing a repetition of lines or features across the exterior of a printed object, especially when light is reflecting off your print at a certain angle.ģD printing has many industry-specific terms. Ghosting is something that causes the surface of your model to display echoes/duplicates of previous features. Ghosting, also known as ringing, echoing and rippling, is the presence of surface defects in prints due to vibrations in your 3D printer, induced from rapid changes of speed and direction.
