Overview
3DLight_OnSite (3DLOS) is a publicly funded research project led by ZÜBLIN, the German subsidiary of the STRABAG group, in cooperation with universities, research institutes, and industrial partners. Launched in February 2022 from the Stuttgart Innovation Center, the project develops mobile construction-site robots that 3D-print non-load-bearing wall elements directly on site. Inspired by the honeycomb structure of bees, the lightweight layer-by-layer concrete walls use less than 50% of the concrete a conventional wall requires — cutting cost, emissions, and waste in parallel. The pipeline runs end-to-end from a BIM model to printable machine instructions for individually mobile robots that operate alongside conventional construction crews.
