You can think of it as being similar to a 39 ft tall (12 m), 75-ton, autonomous 3D printer that spits out carbon-fiber layers at 328 ft (100 m) per minute. Instead of "printing" pieces, it lays carbon fiber sheets in various directions, layer by layer, to build strength and rigidity into each structure. The AFP is capable of traveling laterally up to 98 feet (30 meters) making it fully capable of laying the largest pieces ?" the 91 ft (28 m) long interstage and fairing of the Neutron rocket. These structures would have taken weeks to hand-lay. The AFP can print these in 24 hours
