Can concrete be 3D printed at a 90° angle—without support—and maintain its structure? Vertico conducted a non-planar printing experiment to test that boundary. As the print continued, the structure eventually collapsed, revealing the current limitations of unsupported overhangs in concrete extrusion. Rather than a failure, this controlled collapse provides valuable data on material behavior, structural thresholds, and print path design—moving the industry closer to achieving greater geometric fr
