Additive Manufacturing by Extrusion of Lightweight Concrete - Strand Geometry, Nozzle Design and Layer Layout
In additive manufacturing by concrete extrusion, objects are built up by depositing strands of fresh concrete. The form and size of the strands as well as the order in which they are arranged are decisive parameters for the properties of the resulting construction element. Extrusion of lightweight concrete can be used as a method to construct monolithic structural building elements with an optimized thermal insulation. They may have zones of different functionality and can be augmented by voids to house building technology. This paper discusses the possibilities and limitations in the design of appropriate strand structures and gives recommendations on how strand geometry, nozzle design and layer layout have to be chosen to obtain the desired results.
