Edgar Montejano Presented Research Paper on Developing Resource-Informed Lightweight Lattice Systems at the ACSA 113th Annual Meeting in New Orleans
Presenting at ACSA 2024, New Orleans
Ph.D. student Edgar Montejano Hernandez presented his peer-reviewed research at the 113th ACSA Annual Meeting, held March 20–22, 2025, in New Orleans.
The paper, titled “Developing Resource-Informed Lightweight Lattice Systems: Hybrid of 3D Printable Lattice and 3D Scanned Non-Standard Wood,”is published in the conference proceedings and is co-authored with Associate Professor Dr. Sina Mostafavi.
Project Overview
This research introduces a hybrid building system that combines 3D-printed lattice structures with digitally scanned, non-standard reclaimed wood, including irregular logs and tabletops. High-resolution digital scans—such as point clouds, mesh models, and texture data—inform the computational design of topology-optimized, support-free lattice structures that reduce material use while maximizing structural performance. The study explores two fabrication approaches: attaching 3D-printed lattices directly to shaped wood logs, and using a lattice system to support a reclaimed wood tabletop. The integration of robotic milling with hybrid assembly techniques enables alignment between digital geometries and natural material conditions. By combining reclaimed materials with computational fabrication, the project advances strategies for circular design and construction.
Developed as part of Edgar Montejano’s ongoing Ph.D. research under the supervision of Dr. Sina Mostafavi, this work has been developed at the Hi-DARS Lab (Hybrid Intelligence Design and Architectural Robotic Systems Lab) at the Huckabee College of Architecture, Texas Tech University.
