Overall, the Cornell group reckons that they have addressed the project goal. This means that traditional underwater construction, which is slow, expensive, and disruptive to the environment, could become a thing of the past.
This isn’t the ‘winning’ solution to subsea construction yet, though. The Cornell team will pitch and demonstrate their seafloor 3D printer -driven construction tech in a DARPA ‘bake-off’ in March this year. At the event, they will have to race against five other teams to 3D print an underwater arch, to spec.

American2021 Interesting. Also, MIT has designed a way to use acoustic signals (rather than radio waves) for underwater networking that uses the water (rather than air) as the medium. Though slow (10KB in deep water), it is effective over very long distances. It would take about 23 hours to send a 100 MB file at the bottom of the sea floor using acoustic networking through the water. Reply
