Montana is the first U.S. state to give broad regulatory approval for 3D printing in building construction.
State regulators have approved 3D printed walls as an equal replacement for walls made with concrete masonry units or a standard cored concrete block assembly. The action came after a contractor based in Billings, Montana, filed documents, specifications, and testing reports developed by Apis Cor, a Florida-based construction technology company that holds the Guinness World Record for the largest 3D printed building.
The contractor sought permission to use Apis Cor’s 3D printed process and equipment for a housing development project in Billings and for projects in other areas of the state. Apis Cor says that the cost of a finished home printed with one of its printers can be constructed for up to 30% less than traditionally built concrete block or wood-framed homes.
Regulatory approval for 3D printing applies to all types of construction that follows the state building code. It is not limited to single-family dwellings.
