Black Buffalo 3D Corporation, a leading provider of large-scale 3D printers for construction and a member of HN Inc.—formerly Hyundai BS&C Co. Ltd.— announced its success in working with the International Code Council Evaluation Service (ICC-ES) to revise its ICC-ES AC509 criteria. This update enhances the acceptance criteria (AC) for 3D Automated Construction Technology for 3D printed concrete walls from a single-story building construction to multi-story building construction. The company continues to invest in its 3D construction printers and material science with the intent to become the first 3D construction printing company to meet ICC-ES AC509. With printers developed by its sister company, Hisys (based in South Korea) the latest model is capable of printing buildings up to four stories high.
