3D printing ready for serial production?

What do pizzas, earrings, tyres, jaw implants, spare parts for trucks and locks for aircraft doors have in common? They can all be produced with a 3D printer. The Berlin start-up company BigRep, which claims to be the market leader in the field of large plastic 3D printers, is selling its equipment to ceramic manufacturer Villeroy & Boch, for example, which uses it to manufacture bathtub prototypes. A large airline is also one of the customers.
