Construction Contour Crafting

Construction Contour Crafting is an advanced building technology that uses large gantry robots with multiple nozzles to extrude cementitious materials, such as concrete or mortar, directly onto the walls of a structure without traditional formwork. This process significantly reduces construction time and labor costs while maintaining structural integrity.

Reduces labor costs, speeds up construction times, and minimizes waste associated with traditional bricklaying or casting methods. It also enables more complex geometries and designs than conventional techniques.

Gantry-mounted robotic arms equipped with extrusion nozzles follow a precise digital blueprint generated from Building Information Modeling (BIM) software. The nozzles deposit material layer by layer, creating walls that are then cured to form the structure. This method allows for continuous operation and high-speed construction.

The manufacturing process involves creating the robotic gantries, nozzles, and control systems. These components are typically made from durable metals like aluminum or steel to withstand the rigors of construction environments. The extrusion nozzles require precise calibration for consistent material flow.

During construction, the gantry moves along predetermined paths defined by a BIM model. Nozzles dispense cementitious materials at high pressure, forming walls layer by layer. Each layer is allowed to cure before the next one is applied. This process can be automated with minimal human intervention.

Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and other pre-processing steps required before assembly on-site.
