Amazing.
I am astonished how many things they have done with this. The realization that they could use this technology for any material which undergoes a phase transition reasonably quickly after it leaves the print head.has been key to making 3D printing commercially interesting. They've built metal bridges in situ by using a printer that melts and fuses the metal into a structure.
The other thing it does is to free building from the practice of assembling materials made into simple, generally rectilinear shapes and allows for 100 % organic shapes.

The addition of this, concretelike material and the metal printing that MX3D is using (they have said they will 'print' a metal bridge across one of the canals of Amsterdam later this year) really expands the scope. Imagine what it would look like if new public buildings could be as richly sculpted as a Gaudi building or a piece of art nouveau furniture. Furniture and cabinetry could be made in-place.
Interesting time to be alive.
