3D printing: 'the possibilities are endless'

Printing in three dimensions is becoming more widespread, says Rafal Tomasiak, of Polish 3D printing firm Zortrax, but he has clear ideas of where we will - and won't - be using them.

"The future is the medical sector, which is using it more and more," he says. But we won't be seeing the machines in our homes any time soon, he adds. "The printing process is not as easy as the promotional films present, you need to be a specialist."
