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.

See it in action over at youtube

You can find the script/code over at my github
Feel free to mess around with it, perhaps one day this will show up in a slicer :)
