A Brown University computer science student created a detailed 3D-printed model of the iconic CBR Building in Brussels, featuring all 756 windows. The project combined architecture research, mathematical reverse-engineering, and advanced 3D printing techniques.

Why it matters: The model honors the building's innovative prefabricated concrete design and showcases interdisciplinary skills linking architecture and computer science.

The big picture: The CBR Building, designed by Constantin Brodzki, exemplifies mid-century architectural innovation emphasizing nature integration and rapid construction.

Stunning stat: Printing all 756 window modules was optimized from hundreds of hours to just one week by balancing print quality and speed.

Commenters say: Readers admire the craftsmanship and technical depth, celebrating the fusion of art, math, and technology in this ambitious student project.
