About

Ella Hetherington is a pioneering researcher at the intersection of sustainable construction and digital fabrication, with a primary focus on earth-based building materials and robotic additive manufacturing. Her most significant contribution is the development of Variable Aggregate Impact Printing (VAIP), a groundbreaking methodology introduced in her 2023 paper that automates the assembly of traditional cob—a mixture of clay, sand, and straw—using a six-axis robotic arm and custom tool. This work revolutionizes the use of soft, heterogeneous materials in construction, enabling precise, automated aggregation of discrete particles that were previously challenging to handle with conventional 3D printing techniques. With 2 citations since 2023, her research is gaining traction for its potential to merge ancient building practices with modern automation, offering a low-carbon alternative to cement-based construction. Hetherington’s work is notable for bridging material science, robotics, and vernacular architecture, positioning her as a key innovator in sustainable building technologies. Her achievements include demonstrating the viability of cob as a printable material, opening new avenues for eco-friendly, automated construction that respects traditional knowledge while embracing Industry 4.0 advancements.
