About

Sandra Gelbrich is a pioneering researcher in digital construction and additive manufacturing, specializing in the development of advanced robotic fabrication techniques for concrete elements. Her work centers on understanding the anisotropic properties of 3D-printed concrete, a critical factor for structural integrity in automated construction. In her most-cited paper (2023, 8 citations), she demonstrates that additively manufactured concrete exhibits direction-dependent mechanical behavior, challenging traditional assumptions of isotropy and providing essential guidelines for design and quality control. Gelbrich also advances combined additive manufacturing technologies, integrating concrete spraying and extrusion for continuous production of precision elements (2023, 2 citations), and develops specialized tools for robot-assisted flow production of precast components (2024, 1 citation). Her contributions bridge materials science and digital fabrication, enabling more reliable, efficient, and scalable construction processes. By addressing both fundamental material properties and practical manufacturing challenges, Gelbrich’s research lays the groundwork for the next generation of automated, high-precision concrete construction, making her a key figure in the evolution of sustainable, digitally-driven building technologies.
