RPS (Robotic Plaster Spraying) process building up a volumetric formation, with adaptive thin-layer printing on a vertical surface.
RPS process building up a volumetric formation, with adaptive thin-layer printing on a vertical surface - result of 35 layers, with a final thickness on target surface (overhang) of ~18.5 cm.
Detailed view from the selected prototype within the catalogue of different surface geometries and textures produced with RPS.

Robotic Plaster Spraying, ETH Zurich, 2018-2023
PhD research project
This research investigates the design potentials of combining plaster with a robotic spraying process and proposes a novel, adaptive thin-layer printing method. Research goals address an on-site construction system that is capable of performing continuous robotic plaster spraying on building elements, without the need for additional formwork or tools used in conventional plastering to produce textural patterns and volumetric formations. To support the understanding of the complex-to-simulate material behavior in this process, systematic studies through physical testing are being conducted in order to collect data by visual sensing. The goal is to understand the influence of parameters such as velocity, angle and distance of spraying on the material behavior. This investigation will enable to inform the design process on the combined effect of the parameters prior to fabrication through a digital visualization tool, and to capture the design space of the proposed method. As such, robotic plaster spraying aims to contribute to the field of additive manufacturing and explore the surfaces of architectural spaces, enhancing the bespoke design potential of plaster with a new digital craft.
