Alquist 3D recently dispatched a concrete/mortar ink printer and crew to place a 20-ft. high enclosure for an 8,000-sq.-ft. addition to the Walmart Supercenter in Athens, Tenn. An articulating robot with 48-in. long, 1-in. diameter nozzle shuttled around each wall section perimeter, efficiently printing twin inner and outer layers with precision. The new facility will support the Walmart Online Pickup & Delivery program.

Alquist 3D officials note that the Walmart Athens addition exemplifies their commitment to “transforming how we think about building—whether it’s for commercial retail or the future of housing. The project represents not just a step forward for Walmart, but also for the retail and construction industries at large. Our mastery of cutting-edge 3D concrete printing technology reflects a broader trend toward greener, faster, and more technologically advanced construction.”

The project marks Walmart’s first large-scale 3D-printed concrete technology; positive results inform planning for a second such effort at a sister location. Images: Alquist 3D
