Researchers from the Massachusetts Institute of Technology have developed innovative glass bricks printed on a 3D printer. They resemble LEGO and have strength comparable to concrete blocks. The bricks are shaped like a figure-eight and feature interlocking pins, allowing them to be used in curved construction projects. After printing, the team tested their strength using a hydraulic press and found them to be nearly as strong as concrete blocks. An additional aluminum element on the bottom increases their strength. The development is made from recycled glass and can be easily recycled or repurposed after use. If the bricks are no longer suitable for the current project, they can be melted down and printed in a new mold. MIT Assistant Professor of Mechanical Engineering Caitlin Becker emphasized the importance of recycling glass - if it is not contaminated, it can be recycled almost indefinitely.
