When selected, object will print with 0 infill, and 0 top layers and 1 perimeter. The perimeter is a single extrusion – with no starts and stops – and spirals up to the top of the print. You can still specify the desired number of solid bottom layers. As you might have guessed, this is the preferred setting for printing vases or other single-walled objects. Only one part will print at a time with this feature.
