The aim of 3DLight_OnSite is to achieve significant CO2 savings in the construction industry by developing a continuous CO2-optimized, digitized and automated workflow for the production of multifunctional lightweight components.

The main innovation lies in the conception, development and testing of in-situ manufacturing in the field of additive manufacturing. Materials and digital planning methods for individualized, multifunctional lightweight concrete components are to be developed in order to manufacture them robotically using additive manufacturing. The results are to be applied in construction operations and used, among other things, for housing construction.

The project is funded by the German Federal Ministry of Economics and Technology based on a resolution of the German Bundestag.

To ensure uniform additive manufacturing, the quotient of web speed (e.g. process path of the 3D printer) and volume flow of the extrudate at the nozzle outlet must be constant. Until now, this has not been possible.

By modeling the dynamic material behavior in the print head, the volume flow can be precisely controlled for the first time. Combined with real-time web planning on the CNC controller, a uniform output is achieved for the first time, i.e. web speed / extrusion speed = constant.
