MIT Says Glass Bricks Have Crush Strength of Concrete Blocks
Researchers recycled crushed bottles into 3D-print multilayered blocks as strong as concrete, according to the university.

As 3D printing gains more traction in construction and academia, researchers at Massachusetts Institute of Technology have created 3D-printed glass bricks that have a crush strength comparable to that of concrete blocks, the university announced in a Sept. 20 news release.
For this study, the engineering team used the Glass 3D Printer 3, the latest offering from Rochester, New York-based 3D-printed glass firm Evenline, paired with a furnace that melts crushed glass bottles into a molten, printable material.
The printer then deposits the molten glass in layered patterns in the shape of a figure eight, according to the release. The team added two round pegs onto each printed brick, which enable the materials to interlock — similar to LEGO pieces — and be assembled into larger structures.
