Testing out an idea that while printing, the nozzle can be pressed in to the job at various points to fuse together or "spot weld" the layers and increase overall part strength.

Result: About 20% improved strength

Print Spreed: 60mm/s
Layer height: 0.3mm
Part height: 100mm
Part width: 15mm

4 spot welds, one in each corner.
The nozzle pressed in by 0.3mm for 0.2 seconds.

Feel free to mess around with it, perhaps one day this will show up in a slicer :)
