Concrete Innovation at Scale: Walmart’s 3D-Printed Buildings Mark a Turning Point in Commercial Construction

A Pilot Project That Set the Stage for More

The story began in Athens, Tennessee, where Walmart worked with Alquist 3D to build an almost 8,000-square-foot expansion to support online pickup and delivery. It became the largest fully 3D-printed commercial structure in the United States and an important test case for whether the technology could scale beyond housing.

The work was not straightforward. Alquist has been candid about the challenges of printing such a large structure for the first time, including material management, scheduling, and coordination with a general contractor who had never worked with a 3D printer of this size. Yet despite the hurdles, the project demonstrated that large-format concrete printing could meet the structural and functional requirements of commercial retail.

The second Walmart project, in Huntsville, Alabama, showed what happens once the learning curve flattens. There, Alquist printed a 5,000-square-foot pickup center in roughly seven days of on-site activity, with about 75 total hours of active printing and a crew of only five people. Reports indicate that the project ran ahead of a traditional construction schedule and generated significantly less waste than conventional methods.

These two builds provided the proof of concept Walmart needed to move forward with a more ambitious national plan.

A Landmark Agreement with National Implications

Alquist has now announced a new deal to 3D print more than a dozen Walmart buildings, along with additional projects for other commercial retailers. This is widely viewed as one of the largest commitments to 3D-printed commercial real estate in the country.

A key part of the arrangement involves Sika, one of the world’s largest construction materials suppliers, which will provide specialized mixes for Alquist’s printed buildings. Standardizing the concrete formulations allows Alquist to streamline procurement, reduce freight costs, and accelerate development of more sustainable materials suitable for high-volume printing.

In parallel, Alquist is partnering with a national equipment rental company and a general contractor to create a scalable deployment model. The contractor will own the printers, the rental partner will handle financing and service, and Alquist will provide the printing technology, software, and training. The structure is designed to remove bottlenecks and enable rapid expansion across many markets.

All of this positions Walmart not as a passive customer but as one of the first retailers to adopt an emerging construction technology at meaningful scale.

Why 3D Printing Is Gaining Momentum in Commercial Construction

Large-format 3D printing has made far more headway in residential building than in commercial real estate. Printing a single-family home is complex, but printing a 20-foot-tall commercial structure introduces new technical demands and requires printers with significantly larger reach and precision.

Until recently, the technology simply wasn’t ready for buildings of this size.

The shift is happening now for several reasons. First, manufacturers like Alquist and Icon have developed larger printers capable of reaching commercial heights and widths. Second, software has improved to allow printers to create more intricate, structurally sound wall assemblies. Third, a shortage of skilled construction labor has created openings for robotics-based approaches that reduce the number of workers needed on-site.

In the case of Walmart, printing the exterior walls allows for faster scheduling, fewer dependencies across trades, and reduced material waste. It also opens the door to new design options, such as thicker thermal walls or optimized geometries that are impractical with traditional framing.

As 3D printing becomes more predictable, the economics begin to shift. Faster timelines, lower waste, and fewer labor hours do not eliminate construction costs, but they can make certain projects more viable, especially in markets where demand for pickup and delivery space is rising faster than conventional construction can keep pace.

Growing Pains and a New Construction Workforce

Alquist’s early work with Walmart was marked by what its leadership described as “failing forward,” which is common for first-of-kind builds. They experienced permitting delays, design misalignment, and on-site coordination challenges. None of that is unusual for a new construction method, and by the second project the improvements were clear.

The labor profile for 3D printing is different from traditional construction. While fewer workers are required on site, the work demands advanced training in software, robotics, safety systems, and materials. Alquist has been working with trade schools to build that talent pipeline, and the work appears to appeal to younger workers who are seeking roles grounded in technology rather than traditional manual trades.

If these projects scale as planned, the approach could help ease pressure on the construction workforce, which has been strained by retirements and competition from industrial projects such as data centers and manufacturing facilities.

Competition and the Broader Industry Landscape

Alquist is not alone in its pursuit of large-scale printing. Icon, currently the largest residential 3D printing company, has begun moving into commercial development and recently completed a 3D-printed hotel. Its forthcoming Titan printer is designed for even larger commercial structures, including data centers.

Icon’s leadership has indicated that meeting cost and speed expectations is essential to winning commercial work, particularly in categories like industrial buildings where traditional construction costs are climbing. The company expects to manufacture one Titan printer per month next year, which would represent one of the fastest hardware scale-ups in the industry.

The combined momentum of Alquist, Icon, and other emerging players suggests that commercial-scale printing is moving from the margins to the mainstream. Walmart’s commitment accelerates that shift by demonstrating demand at a level that attracts materials suppliers, contractors, and capital markets.

Where This Leaves the Industry

Walmart’s decision to build more than a dozen 3D-printed commercial structures is more than a construction update. It marks a broader change in how retailers may think about the built environment.

3D printing offers
• A faster path to adding capacity at existing stores
• A way to standardize smaller operational buildings across many markets
• An opportunity to reduce material waste and incorporate more sustainable mixes
• A construction model that is less vulnerable to labor shortages

While the technology is not ready for every building type, its momentum is unmistakable. The industry has waited years for a major commercial adopter to demonstrate that these projects can be built on time, at scale, and with repeatable processes. Walmart, through its expanding work with Alquist, appears ready to play that role.

Making Sense of the Moment

The move to 3D-printed commercial buildings reflects a larger truth about modern retail. Physical infrastructure must evolve as quickly as customer expectations, and the old timelines for construction no longer fit the pace of omnichannel commerce.

Walmart’s partnership with Alquist suggests that the next phase of store evolution will not rely solely on digital tools or automation inside the building. It will also come from innovation in how the buildings themselves are created, expanded, and brought online.

The retail industry has no shortage of technology pilots. What it often lacks is proof that emerging tools can scale. This agreement indicates that one of the most traditional parts of the business, commercial real estate development, may be the next area to change more rapidly than many expected.
