Retail giant Walmart has initiated one of the largest 3D printed commercial real estate projects in the US in Athens, Tennessee.

The nearly 8,000-square-foot, 20-foot-high expansion was designed in partnership with 3D printing and robotics specialist Alquist 3D.

The move is part of Walmart's broader goals of becoming more environmentally friendly, using technology to attract customers, and accelerating the construction process.

The expansion will be dedicated to expanding Walmart's online pickup and delivery (OPD) program, and marks the first time Walmart has integrated 3D printing technology at scale.

Walmart said that due to the success of this project, it is planning a similar second project.

Mike Neil, Walmart’s vice president of new construction, highlighted the retailer’s commitment to innovation and new technologies as key reasons for choosing the partnership with Colorado-based Alquist 3D.

"Alquist presented the best ability to work with due to their deep knowledge of 3D materials, robotics, and desire to take on an ambitious and unique project."

The retailer added it considered several companies in the field, with Alquist standing out for its expertise and its ability to partner with industry experts including SIKA and RIC Technology.

Although there are still few commercial buildings using 3D printing for construction, interest is growing and several builders and companies around the world have been exploring and investing in 3D printing for commercial properties.

Last September, Canadian builder WSP announced that it had begun researching new applications for 3D printed concrete, including infrastructure and clean energy projects.

Other well-known firms that have recently invested in 3D printing include Texas-based ICON, and British CDC Group and Skanska.
