Ironing has little to no effect on non-flat surfaces, Ironing Off (left), Ironing On (right) With that said, ironing will not have a significant negative impact when printing such models, it will just unnecessarily increase the print time. It's also not useful for objects which do have flat areas, but these flat areas are not aligned parallel to the print bed. Ironing is not useful for round objects, figures, and organic shapes in general. Ironing can also be useful when you want to glue two pieces together and need the surfaces to be as flat as possible so that the gap between them is minimized. Ironing is useful for prints with flat top surfaces, like nameplates, logos, badges, boxes, lids, etc. The ironing toolpath is planned for a small extrusion, but the nozzle is physically still the same size, so some plastic will bleed over the edge. The risk is increased during summer heatwaves.Īnother downside is that the edges will be a tiny bit fuzzy or less sharp. This might a problem mainly when printing with PLA, because of its low-temperature resistance. If you're ironing a big surface area, on some machines you might experience heat creep and eventually, a clogged hotend because the extrusion is very small and slow during ironing. You can see how much print time will be spent on ironing in the preview. The main downside is increased print time as the second phase of the top infill is performed with very small spacing between ironing lines. Ironing OFF (left), Ironing ON (right) Macro comparison of Ironing OFF (left), Ironing ON (right) Downsides Ironing is angled at fixed 45 degrees compared to the first phase of normal top infill as this approach produces better results. That means the nozzle will go over the same spot several times. The spacing between individual ironing passes is usually a fraction of the nozzle diameter. The nozzle also extrudes a small amount of filament to fill in any holes in the top surface. Ironing smooths flat top surfaces by running a special second infill phase at the same layer.Īs the hot nozzle travels over the just printed top layer, it flattens any plastic that might have curled up. This option is not available when PrusaSlicer is in Simple mode.
