Historically, 3D printing has failed to take off in commercial construction due to what Patti Harburg-Petrich, then a principal in the Los Angeles office of U.K.-based engineering firm Buro Happold, said in 2023 was the result of lagging code adoption.
“The issue is that it takes a really long time for new technologies and building innovations to get incorporated into the building code,” Harburg-Petrich said. “That’s for good reason: safety is the highest priority, so the building code is inherently conservative. But that also makes it a long, time-consuming, expensive process to get new technology incorporated into the code.”
However, contractors continue to experiment with the building method. FMGI, a general contractor out of Woodstock, Georgia, built a 3D-printed addition on WalMart’s Athens, Tennessee, location in partnership with Greeley, Colorado-based Alquist 3D. Work on a second project between the pair — a 5,000-square foot addition to a Walmart Supercenter in Huntsville, Alabama — will start this month, according to FMGI’s website.
The ICC already has measures in place for 3D printing on the residential side of construction, which includes standards for tiny houses and for the general residential code.
