Some slicing programs allow for advanced experimental settings. One such is Simplify3D in which we, just for the fun of testing, 3D-printed a #3DBenchy with zero outer layers – such as follows:
- Perimeters (shells): 0
- Top solid layers: 0
- Bottom solid layers: 0
- Infill: 25%
In other words, the slicer made a print file that just prints the infill and no layers. Surprisingly the model printed quite well.
