Quantum Leap: 3-D printing going to be a new reality

Over the last decade, home and office printers have remained pretty much the same, barring a few cosmetic changes. The biggest evolution is happening elsewhere, where printers are being used to manufacture actual products using digital models — from electric switches, toasters and pens to human skin, kidneys and food.

Early 3-D printers are already in use. HP has launched a few in India to print plastic parts like car panels and electric switches. Plastic components (non-critical) of aircraft are being made using 3-D printers. Narayana Health uses 3-D printed heart prototypes.
