Want to take your bike to the mountainside? It can easily be done simply by printing out the frames and other parts of a bicycle and put it together. British firms - Renishaw, the U.K.'s only 3D-printing manufacturer and Empire Cycles, a bicycle design company in the west of England - come together to create an innovative framework of world's first 3D-printed metal bike.
The evolution of the 3D-printed gun continues. A Wisconsin man has improved on the original "Liberator" design released by Defense Distributed, bringing the cost down to $25.
