Walmart has partnered with 3D concrete printing company Alquist 3D and general contractor FMGI to complete construction of its second freestanding, 3D-printed store addition. Working with the two firms, Walmart printed the 16-foot concrete walls of the structure, which will serve as an extension of the grocery pickup area in Walmart’s supercenter in Huntsville, Ala. Set to open the week of May 5, the completed Huntsville addition will serve as the retailer’s online grocery pick-up and delivery location as part of an overall store remodel. Other companies working on Walmart’s Huntsville commercial 3D printing project included Sika USA, which supplied customized concrete mixes formulated to address varying environmental conditions. In addition, Alquist’s robotics partner RJC Technology, which furnished robotic systems designed to achieve high-precision printing with reduced labor requirements. “In a commercial construction world that pays so much attention to project timelines and costs, our work with Walmart shows that 3D printing isn’t just a novelty – it’s an innovation ready to scale for retail and other industries,” said Patrick Callahan, CEO of Alquist 3D. “This second project clearly demonstrates how retail expansions can be faster, more cost-effective and less wasteful, paving the way for broader adoption for large-scale commercial builds.”
