To prevent warping of the metal in welding, the bead is not run continuously in one line. A small bead is run, and then the welder lifts the stick and goes backwards and runs another small section. I wonder if such a slicing strategy implemented in the slicer could prevent alot of the warping issues seen in 3D printing. The picture below illustrates the back stepping strategy.
The slicer could provide the option to set the maximum continuous length of a printed segment, before it back steps. Could also give the option to skip segments, so there is a gap between segments, that get filled after the layer is completed. The outer most walls would of coarse be printed as one continuous line for quality.
Solid infill would also run similar strategy.
