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.
