Ironing has little to no effect on non-flat surfaces, Ironing Off (left), Ironing On (right)ĭon’t forget, that some models can be printed upside down. It will just unnecessarily increase the print time. With that said, ironing will not have a significant negative impact when printing such models. 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.

It 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. For PrusaSlicer, we implemented Neotko’s “Neosanding” at 45 degrees as in Kisslicer. Kisslicer integrated Ironing with a small twist: The second phase is not perpendicular to the first phase, but at 45 degrees, which Jonathan, the author of Kisslicer, validated to produce better results. The “Neosanding” was later integrated by Ultimaker into their Cura slicer. Neotko prototyped “Neosanding” – a smoothing of top surfaces in Simplif圓D by running a second infill phase at the same print height with zero or a tiny extrusion rate perpendicularly to the first infill run. The Ironing idea was first proposed in 2016 by the Spanish user “Neotko” on the Ultimaker community forum. You will not find ironing in the previous versions of PrusaSlicer. At the time of the release of this article, PrusaSlicer 2.3 is available as a release candidate version.
