The latest in construction are drones that use 3D printing to lift buildings from the air

Today’s drones are often developed for the battlefield or as a defense or delivery system. However, its functionality can go further and help in the construction of buildings. in inaccessible places (Like other planets or natural satellites), at least that’s what researchers at Imperial College London and the Empa Institute in Switzerland propose.

Their study, published in the journal Nature, has generated a slew of Semi-autonomous drones that will work collaboratively, It will be called Aerial Additive Manufacturing (Aerial-AM) and they will work as aerial bricklayers creating 3D constructions suitable for human existence in space.



“We’ve tested the concept that drones can operate autonomously and simultaneously to construct and repair buildingsAt least in the laboratory,” confirmed lead author Mirko Kovac from Imperial’s Department of Aeronautics and Empa’s Center for Robotics Materials and Technology.

As detailed in nature, the drones will be organized into two groups in charge of different tasks. One would be composed of observers (scan drone) operate and the other has to build (make a drone) Both parts will be based on digital construction plans that will have to be analyzed to ensure the drones follow instructions and build the structure correctly.

Although drones were trained to build well, human supervision will be importantTo correct the work of machines.


The product can be printed in any size.

The materials from which the Build Drones will build the buildings will be distributed through a mouthpiece That is the drone, where cement or liquid concrete can be placed. This system has already been used for large infrastructure.

However, 3D printing of these drones will be done in mid-flight, which destabilizes the construction. To overcome this challenge, researchers nozzle can run later And, thus, they managed to compensate for the speed of the drone.

For their part, the scan drones will be in charge of delivering remote signals to level up the work of the ‘bricklayer’ drone. They will be able to adopt digital schemes To accommodate geometric variations structure that may appear.


According to Andy Mogenson, when closing their eyes to sleep, some astronauts see "radiant glow",

lab test

Although its operation in real life has yet to be confirmed, researchers have been able to test it in a lab. He claims that the prototype is Accuracy of about 5 millimeters.

However, it should be noted that it has been tested on simpler structures than it may be able to manufacture in the future. has been one of them 2.05 m 72-layer cylinder, made with expanded polyurethane; second is done 18 cm. second cylinder of 28 layers ofMade of a material similar to cement.
