PROJECT TOPICConstruction, Infrastructure & Maintenance
Automated Concrete 3D Printing Gantry
An automated construction concept exploring large-span Cartesian coordinate gantries, continuous progressive cavity mortar pumps, and non-slump concrete rheology monitoring for on-site structural fabrication.
Additive Construction & Structural Topology
- ✓Eliminates wooden concrete formwork, drastically reducing construction material waste.
- ✓Enables complex curved and topologically optimized structural wall geometries.
- ✓Maintains layer adhesion through automated nozzle height and extrusion rate regulation.
The Engineering Challenge
Problem / Objective
Conventional architectural formwork is labor-intensive, wood-waste heavy, and constrains structural designs to rectilinear shapes.
