Flipped 3D printer makes giant objects

A 3D printer that can produce large items such as plane parts has been developed.
The Infinite Build device prints layers of an object vertically, rather than horizontally, allowing for much longer items to be produced than had been previously possible.
It was developed by Stratasys. Boeing plans to use it to print plane parts.
