Since the 1920s, the way to make a car has been to construct a metal shell bearing all the stresses, based on load-bearing floors, pillars and panels hammered out by huge presses costing millions of dollars.
Several companies are developing similar bone mending products for small bone fractures but with no load-bearing characteristics.
Steel also adds flexibility: The absence of load-bearing walls means windows and doors can be placed just about anywhere.
The load-bearing beams of the Opera House shells he called spidsgattere, in homage to the sharp-sterned boats his father made.
The advantage of this arrangement is that it can be scaled up more easily than a semi-rigid design, since the envelope is not load-bearing.
In civil aviation it is mainly to achieve fuel benefits, but in other fields it can help increase manoeuvrability or an aircraft's load-bearing capacity.
Planes already use metallic foam in non-load-bearing parts, to reduce weight.

Wilhelm Meiners and his colleagues at the Fraunhofer Institute for Laser Technology in Aachen, Germany, are one group working to extend the technology to print reconstructive facial plates and even load-bearing artificial joints, such as hips, which could be customised for each patient.
The Monadnock is a good place to get a practical sense of how quickly these innovations were catching on: the original northern half of the building consists of traditional load-bearing walls that are 6ft thick at the bottom, while the southern half, constructed only two years later, uses the then-revolutionary metal frame for drastically thinner walls that go just as high.
There are stored-value cards, which allow customers to load money onto a microchip-bearing piece of plastic.
