I am experiencing a minor layer separation when printing a body for a tipping-bucket rain gauge, which is basically a hollow tube with thin walls (3 mm). I am using Prusa I3 MK2 and a Fillamentum ABS white plastic. The model has been sliced in Siplify 3D with the following settings:

  • layer height: 0.2 mm
  • perimeter shells: 3 layers (almost entirely fills up the wall)
  • extruder temperature: 230 °C
  • printing speed: default - 50 mm/s, outline - 35 mm/s, infill - 35 mm/s

Is it possible to prevent the irregular and layer separation by adjusting some of the settings, and not significantly increasing the printing time, which is already 13 hours?

The best thing you can do for a large ABS print is to have an enclosure heated to 50C or better. For example, see this, this, this, and other search results.
