The adoption of digital solutions in construction has been proved to increase work safety, and it supports the circular economy by reducing material waste and simplifying resource recapture. Additive manufacturing processes have the great advantage of being able to achieve flexibility in the geometry of the outcome. This characteristic makes additive manufacturing particularly suitable for constructing efficient forms that are difficult to create with conventional manufacturing techniques and results in a significant reduction in the quantity of material used. Such forms could be achieved through the use of novel algorithm-aided design (AAD) tools, which are already commonly used in other industrial sectors, such as automotive and aerospace industries. The use of computational design to create new structural forms has been limited by the traditional building production process, which does not allow for freedom of design. Hence, the application of computational design tools to freeform design has often been limited to a few explorations in pioneering architectural applications. With the advent of additive manufacturing process in construction, the use of structural optimisation could potentially enable the realisation of a new generation of optimised structures. Current research efforts aim to combine additive manufacturing with optimisation tools to solve issues related to manufacturing processes (such as overhang) or exploit anisotropy in materials to find new optimal solutions Foreword Concrete additive manufacturing Shotcrete additive manufacturing Powder bed additive manufacturing Wire and arc additive manufacturing Advanced modelling for additive manufacturing in construction Opportunities and future perspectives
