A Chinese university has built the world's longest 3d-printed bridge. The creation has a(long) of 26.3 meters and a width of 2.6 meters. Its design came from    the historical Zhaozhou Bridge(build) in A.D. 605.

Though the ancient Zhaozhou Bridge required decade to build, the team spent only 450 hours(complete) all of their new bridges concrete parts., the bridge's cost came in at just two thirds ofof an ordinary bridge.

The bridge consisted individual 3D-printed concrete units, each of   them approximately 3 by 3 by 5 feet. The sides, influenced by the Zhaozhou Bridge,  (make) with 68 single concrete plates moved into place by robot arms.

The leader of the team noted that "the demand for labor in construction projects will be in short supply(increasing)" in the future. If China cannot find people to build bridges, "intelligent construction(become) an important channel to solve this problem".

There have been other 3d-printed architectural projects over the last few years, as the technology has become(popular) than before. A team at MIT built a sample house in 14 hours. If there are ever houses on Mars, NASA suspects the houses also will be built by robots using 3D printing.
