About

David Leggett is a researcher at the forefront of robotic construction and digital fabrication, specializing in adaptive formwork and non-standard manufacturing processes. His work reimagines traditional casting and cutting techniques through the integration of robotics and computational design. Leggett’s most cited paper, "Robotic variable fabric formwork" (2018, 8 citations), introduces a novel method for producing complex geometries by replacing rigid molds with robotic-controlled fabric, significantly reducing material waste and enabling freeform concrete casting. This contribution challenges conventional construction paradigms by merging flexibility with precision. In "Freeform Volumetric Fabrication Using Actuated Robotic Hot Wire Cutter" (2021, 2 citations), he advances hot-wire cutting beyond ruled surfaces, developing an actuated end effector that allows for true three-dimensional carving of foam and other materials. Though early in his career, Leggett’s work has been recognized for its potential to democratize complex architectural forms and minimize environmental impact. His research sits at the intersection of architecture, engineering, and robotics, offering scalable solutions for on-site and off-site fabrication. For students and researchers, Leggett exemplifies how interdisciplinary thinking can transform age-old construction methods into agile, sustainable processes.
