SQ4D builds full-size concrete homes, commercial structures, and infrastructure with its ARCS construction 3D printers. The New York company has marked the field with several permitted projects, including the first U.S. 3D-printed home for sale and a Habitat for Humanity home in Islip with more than half its structure printed, including the foundation, walls, and insulation. It also sells ARCS printers and provides education for builders entering construction 3D printing.
X-Hab 3DBorn from an effort to address rural housing challenges in Alaska, X-Hab 3D develops robotic 3D concrete-printing systems for construction. The State College company grew out of Penn State engineering, architecture, and additive-construction research, bringing together rugged mobile or fixed-site printers with compatible materials and design software for projects ranging from homes to infrastructure. Its systems have been tested in demanding settings including sub-Arctic Nome.333248STATE COLLEGE, PA
