3D Printing a Concrete Spiral Staircase with AdaOne

This video showcases a new application developed within the PrintCrete project: the robotic 3D printing of a concrete spiral staircase.

Before printing the concrete staircase, a polymer support tool was first manufactured to serve as the base structure for the process.

Using AdaOne, both the polymer tool and the staircase were sliced, simulated, and prepared for robotic production. The project demonstrates how robotic additive manufacturing can be applied to prefabricated concrete elements with complex geometries while maintaining a controlled and repeatable process.

The PrintCrete project focuses on advancing 3D printing for sustainable prefabricated concrete elements by combining material development, robotic manufacturing, and industrial workflows. The initiative brings together industry, academia, and research organizations to support the adoption of concrete additive manufacturing in construction.
