Concrete printing in 3-D will put an end to boring buildings

Construction is one of the largest industries in the world economy - worth A$10 trillion globally (equivalent to 13% of GDP).
But construction has suffered for decades from remarkably poor productivity compared to other sectors. While agriculture and manufacturing have increased productivity 10-15 times since the 1950s, construction remains stuck at the same level as 80 years ago.
That's because construction remains largely manual, while manufacturing and other industries have made significant progress in the use of digital, sensing and automation technologies. We and other research groups see 3-D-printed concrete as a possible solution to these problems. The technique will likely also give architects the freedom to inject more creativity into their designs for new structures.
