Abstract: Recent trends have shown that digital fabrication and construction materials and methods are coming together in a significant way. The most visible evidence of this has been the implementation of 3D printing technologies in the construction sector through the increasing availability of large scale systems. Inherent to the process is the ability to produce geometrically unconstrained, high resolution customised architecture. In this work, the authors present a concept in which 3D sand printing is coupled with casting high performance fibre reinforced concrete (HPFRC) to produce a composite material that can take advantage of the freedom afforded by 3D printing as well as the strength of HPFRC. A prototype slab element has been digitally designed and topologically optimised. The printed element consists of a 6 to 10 mm thin shell structure with internal voids that is then used as a stay in place formwork and infilled with a HPFRC to produce a final element that can be functional and more efficient structurally as well as aesthetically pleasing. Constraints discovered in the production of the prototype and the potential of this method to further produce custom architectural elements are discussed.
