Abstract:

Mass customizing of building components allows new conditions to explore aesthetic and
sustainability in architecture. However, such possibilities tend to require the use of
expensive and heavy digital fabrication machinery, which is seldomly available in most
regions on the planet. In this context, this paper presents a research in progress that
explores Augmented Reality (AR) to support craft production of customized stereotomic
components. As a portable technology, the work examines the potential of AR to
materialize design solutions that are geometrically complex and variable. Considering the
current research on augmented fabrication processes, this work contributes to producing
variable building components for stereotomic construction with a focus on earth-based
materials. Extending the findings of a recently completed PhD thesis, the work replaces
the use of a robot with the HoloLens glasses and Fologram application to produce low-
cost and reusable molds. This augmented fabrication setup allows the human control of
the production of variable molds, ready for casting and assembly of stereotomic
components. This work addresses several of the NEB and UN SDGs goals
