(Image credit: Tom's Hardware) For years, 3D Concrete Printing (3DCP) has been an experimental novelty. Alquist 3D, based in Greeley, CO, is pushing the technology past the demonstration phase with their A1X, a robotic arm printer that lays down inch-thick layers at a whopping 200mm/s. This new approach to construction cuts down on time and wasted material, while also requiring fewer people. Alquist 3D is partnering with construction firm FMGI to build more than a dozen expansions on Walmart locations across the country using the new tech. Alquist’s most ambitious build isn’t 30 new Walmarts or the first 3D printed house in Virginia . It’s the ecosystem the company is setting up to take 3D printing from the lab to the construction site. By teaming up with equipment distributors Hugg & Hall and general contractors like FMGI, they are solving the scalability problem that previously held back the technology and labor shortages that plague construction in general.…
