New 3D-Printed Concrete Technique Reduces Weight, Adds Funky Shapes for Structure

A team of architectural researchers have figured out how to 3D-print concrete structures using a fraction of the material typically used. The team, led by architecture professor Mania Aghaei Meibodi and researchers Alireza Bayramvand and Yuxin Lin of the University of Michigan's Taubman College of Architecture and Urban Planning, call their technique the "Shell Wall" method. It uses computational design and a robotic-arm print head to create funky-looking shapes that have been precisely...
