Editorial: Additive manufacturing in construction

The adoption of digital solutions in construction has proved to reduce the environmental footprint in the building sector while supporting the circular economy and increasing work safety. The application of additive manufacturing (AM) [or else 3D printing (3DP)] technologies contributes to reducing material waste, simplifying resource recapture, and achieving geometrical flexibility in built design. All these features make AM particularly suitable for realizing a new generation of resource-efficient technologies in construction. Indeed, the use of computational design to create new structural forms has been limited by the conventional building production processes, which often does not allow to complete design freedom. With the advent of AM processes in construction, the use of structural optimization tools could potentially enable the realization of a new class in optimizing structures.
