CONSTRUCTION 3D PRINTER。
NOT ANYMORE...NOW THEY ARE PRINTED.
这些是massive 3d printers，that build houses using concrete.
First a digital model of the building is created，where every detail is calculated.
then the machine begins layer by layer it extrudes a concrete mixture forming walls directly on sight.
NO bricks，NO wasted materials.
the process is fast and precise.
sometimes a house can be built in just a few days.
this technology reduces costs and speeds up construction.
and it allows designs that are impossible to build by hand.
this is not the future.
this is happening now.
