Print a shape as if it were a raft

[SteveInOR]

I'm not sure where the misunderstanding is. I already have an STL file of a shape that is 200mm by 100mm and a thickness of 0.84mm. If I set a quality of 0.28mm, the slicer is going to create three layers of zigzag lines but those lines are going to print right next to each other to make a solid layer. I do not want a solid layer. I want a layer that is made up of zigzag lines with space between the lines.I think I figured this out on my own. Using PrusaSlicer, I set my bottom layers to 0 and my top layer to 1. I chose a Fill density of 60% and a Fill Pattern of Line. With the density setting, I can adjust the space between the lines. At a thickness of 0.84mm and a layer height of 0.28mm I get no bottom layer, two infill layers of zigzag lines in opposite directions with gaps in the lines and a top layer of zigzag lines with no gaps. My 60mm x 40mm test print took much less time and was more flexible than the same shape sliced with solid layers. It's not very pretty, but this piece is never seen.
