State of Montana gives broad regulatory approval for 3DCP Construction 3D Printing
Building code regulators at the US state level in Montana have made history as the first to approve 3D printed walls as an equal replacement for walls made with concrete masonry units (CMUs), or a standard cored concrete block. The approval was granted to Tim Stark, a contractor based in Billings, Montana, after filing documents, specifications, and testing reports developed by Apis Cor, the Florida-based construction technology company that holds the Guinness World Record for the largest (volume) 3D printed building globally.
