Bras and guitars: What people today are 3D printing

3D printing has been threatening to come of age for a long time now.

The organisers of this year's 3D Print Show in London, held last weekend, claim it is about to change the world, in the same way the internet changed things in the 1990s.

Whether or not it moves into the mainstream, advances in 3D printing technology are certainly allowing more and more intricate objects to be made, by a vast array of designers - from architects to fashion students.

BBC News caught up with exhibitors at this year's event to see what 3D printers can make - including two finalists from the 3D4D Challenge, inviting contestants to use 3D printing technology to devise products that will improve the incomes and livelihoods of people in developing countries.
