Inside the body shop

摘要

Arobotic lawnmower keeping the grass neat and tidy outside a modern industrial building in Carrigtwohill, near Cork in Ireland, is a good indication that something whizzy may be going on inside. And so it proves. The airy production hall contains row after row of 3D printers, each the size of a large fridge-freezer. The machines are humming away as they steadily make orthopaedic implants, such as replacement hip and knee joints. Even though several hundred employees' cars are parked outside, the hall is almost deserted. Every so often a team appears, a bit like a Formula One pit crew, to unload a machine, service it and set it running again to make another batch of implants.
