In recent years, large-scale and fully-remote 3D printing with robots has garnered significant interest in construction applications. Combining the design freedom of 3D printing with a robot's versatility offers unique and promising opportunities for how 3D objects can be built in the future. However, a robot's lack of vertical mobility and high dependency on terrain for horizontal mobility still limit the printing of objects with arbitrary sizes and the choice of print locations. To overcome these limitations, we propose combining multicopters with 3D printing. We study the feasibility of this combination by investigating the positioning accuracy of multicopters and developing two representative 3D printing testbeds for large-scale and fully-remote 3D printing applications.
