3D printing with a normal 2D printer

Is it possible to produce a 3D model with a normal printer? According to researchers of the North Carolina State Unversity it is. How? Simple, Everything needed is the sheet, a household printer such as an inkjet printer, and infrared light. The printer prints black-inked lines onto the plastic sheet, which, under the heat of the infrared light, bends – but only its inked parts, as the printed lines absorb more energy from the light, which leads to the desired 3D shape.
