The new technique, inspired by nature, involves multiple drones working together to build from a single blueprint.
A mini-swarm’s worth of drones have been trained to work together to 3D-print some simple towers. One day, the method could help with challenging projects such as post-disaster construction or even repairs on buildings that are too high to access safely, the team behind it hopes.
Inspired by the way bees or wasps construct large nests, the process has multiple drones work together to build from a single blueprint, with one essentially checking the others’ work as it goes. One drone deposits a layer of building material, and the other verifies the accuracy of everything printed so far. The drones are fully autonomous while flying, but they are monitored by a human who can step in if things go awry. Read more here.
