Ehsan Baharlou presented his research titled “Eco-resilient Tectonics: Living Building Materials in Multi-species Earthen Construction” on March 22 at the 113th ACSA Annual Meeting Proceedings, Repair, in New Orleans. The work investigates how additive manufacturing can redefine earthen construction by integrating ecological thinking into material formulation. The study develops a 3D printed earth mixture capable of supporting biological growth through a multi-species approach. Using Pleurotus ostreatus as a mycelium composite and Raphanus sativus as greenery, the resulting wall prototype demonstrated successful colonization, structural performance, and insulation potential. The research advances sustainable construction by positioning living materials as regenerative components within architectural systems.
