3D printing in thin air

The robotic hand 3D prints strands of plastic in the air which can be most any shape and which apparently solidify very quickly – 3D printing in thin air.

Working in the same manner as the “3D printing pen” except instead of your shaky hand trying to make a recognizable shape from an ooze of hot plastic cooled by a fan, this process uses two thermosetting polymers which set when combined by a precision robot actually 3D Printing in space.
