Most digital concrete technologies do not allow adding reinforcement during the production, which complicates the compliance with structural integrity requirements and limits their market to (try to) compete with inexpensive masonry walls. In this work, we present a wide range of new possibilities to reinforce digitally fabricated structures, namely the aligned interlayer fiber concept, the use of knitted textiles and the Mesh Mould concept. We will also discuss the potential to reduce the required minimum amount of reinforcement when using 3D printing processes generating weak interfaces between layers. These new possibilities illustrate that digital fabrication offers a wide range of yet unexplored opportunities for fast, sustainable economic design and production of reinforced concrete structures.
