Large Scale Concrete Additive Manufacturing

Introducing COBOD BOD3, an additive machine blending the power of AI and robotics for construction. This machine extrudes concrete filaments through a pipe-pump-nozzle system to create CAD-controlled prints.

Design

Each print begins with a CAD model defined by a single polyline that serves as the toolpath. This line represents the exact path the nozzle will follow. The structure is created by repeatedly tracing this path, looping around the outline, and stepping upward after each lap to build successive layers.
