Projekt 3DLight_OnSite

Reducing CO2 Emissions through 3D Printing of Structural-Optimized Concrete Walls Using Mobile Construction Robots

Project Description

The aim of the 3DLight_OnSite project is to reduce CO2 emissions in the construction industry by developing an end-to-end CO2-optimised digitised workflow for the production of multifunctional lightweight components with graded properties. The primary innovation lies in introducing lightweight construction through the conceptualization, development, and testing of in-situ manufacturing in additive manufacturing. Materials and digital planning methods for personalised, multifunctional lightweight concrete components that are robotically additively manufactured are being developed.

The knowledge gained will gradually be applied to construction operations. With the focus on CO2 reduction and a fully digitised planning and manufacturing process, the project explores aspects of combining different specialty concrete within a component and new manufacturing processes for multifunctional lightweight concrete components. The digitised, robotic 3D printing construction process enables significant CO2 savings in construction by using CO2-intensive materials only where they are needed for strength and durability, while using less material or materials with a lower CO2 footprint in other areas.

The project bridges the gap between fundamental research and industrial application by testing and validating the results through reference components from practical applications.
