Additive Fabrication of Natural Material Through Mixed Reality

Mixed reality construction expands the possibilities of traditional construction methods across multiple dimensions. In exploring these possibilities, various research trends have emerged, including the use of natural materials, the construction of complex geometries. Building upon these existing studies, this paper pro-poses a workflow for additive construction using natural materials within a mixed reality environment, and validates its feasibility through a practical project. By combining discrete design rule-setting with human interaction in mixed reality, the workflow simplifies the processing, fabrication, and assembly of irregular materials. In this process, discrete design—as a form of additive manufacturing algorithm—enables natural materials to be aggregated in a structured manner, forming construction systems that are both random in appearance and operable in practice. This approach takes advantage of the small volume of offcut materials, and the high mobility of discarded natural components, while also leveraging mixed reality technology to reduce the assembly complexity typically associated with discrete design.
