Robotics specialist cites 3D-printed concrete home milestone

An industrial and consumer 3D-printing equipment developer reports completion of the world’s largest permitted project of its kind to date: A three-bedroom home whose foundation, exterior walls and interior partitions were printed in 48 hours over a six-day window at a cost below $6,000. SQ4D deployed its Autonomous Robotic Construction System (ARCS) for the 1,900-sq.-ft., Calvern, N.Y. project.

ARCS is a gantry-style 3D printer whose shuttle guides a mix hose and nozzle along lateral and longitudinal paths, placing low slump mixes in beads or layers approximately 1-in. thick and 4-in. wide. Powered by patent pending technology, the digitally driven system reduces labor to as few as three crew members by consolidating upward of 20 manual, labor-intensive processes behind  the home structure and enclosure. Developers anticipate future print cycles to be half those logged in pilot projects. Completion of the world’s largest permitted 3D printed home, they contend, supports the SQ4D tagline: “Changing the way the world is built.” — 844/773-3669;
