  • Infrastructure projects are just as important as housing to the additive construction (AC) market segment, and structures used for underwater applications like coastal resilience have steadily become one of the most popular use-cases amongst the growing number of AC-for-infrastructure projects emerging in the last few years. The most recently announced examples in this sub-surface construction category signal that, soon enough, AC users will no longer be content to build off-site: they’ll print their projects directly under the water. Last week, Sarah Saunders wrote about a DARPA-backed projec
