Montana has become the first state to approve 3D-printed walls as an equivalent replacement for walls made from concrete masonry units (CMUs) or standard cored concrete blocks.

The approval was granted to Tim Stark, a contractor based in Billings, Mont., after filing documents, specifications, and testing reports developed by Apis Cor, a Melbourne, Fla., construction company that 3D-prints houses and buildings.

“In so many states, regulations are getting in the way of building more homes,” said Stark. “I’m proud of my home state of Montana for being so forward-thinking and leading the way with this approval of 3D printing as a modern construction method on par to CMU block construction, which opens the door instead of closing it.”

A finished home printed with an Apis Cor printer can cost up to 30% less than a traditionally built concrete block or wood-framed house.
