A 3D printer translates a G-code to basic instructions. The code set the heat of the nozzle, its position in space, the amount of material that passes through it and the speed of its movement.
In fact, a 3D printer can do more than just 3D print. By manipulating G-code and controlling these parameters, the printer welds fabric surfaces and enables the creation of inflatable structures. controlling the speed of the movement allows to join up to four fabric surfaces arranged one on top of the other.

The slipper is a prototype made using a single G-code on the 3D printer. By controlling the route , the speed and the segments which use filament the fabric is welded and the sole is printed on top of it.
