Black Buffalo 3D Corp., a global supplier of large-scale construction printers and proprietary cement-based ink, worked with the International Code Council’s Assessment Department in Itasca, Ill., To expand ICC-ES criteria AC509 – 3D Report on Automated Construction Technology for 3D Concrete Walls of a Single or Multi-Storey Building.

Operating until recently as Hyundai BS&C Co. Ltd., New York-based Black Buffalo 3D aims to increase awareness, efficiency and utility of additive manufacturing in construction. It continues to invest in printers and materials science, with the intention of becoming the first to meet ICC-ES AC509 criteria. With printers developed by sister company Hisys, based in South Korea, its latest model is capable of printing up to four-story buildings.

“We want to build trust and prove the security of our technology in a way that no other construction 3D printing company has done before,” says Jenn Christman, Product Specialist. “Black Buffalo 3D was created to increase the acceptance of printing in the construction industry, revolutionize traditional construction techniques, and unlock the potential of large-scale printing.” The latter concept has the potential to help governments, businesses and non-governmental organizations respond to a number of infrastructure or affordable housing and accelerate disaster recovery efforts, she adds.

ICC-ES is a non-profit, limited liability company that performs technical evaluations of construction products, components, methods and materials. Agencies use assessment reports to help determine code compliance and enforce building regulations. Manufacturers or suppliers use reports as proof that their equipment, products and materials meet code requirements and warrant regulatory approval. – Black Buffalo 3D Corp., American subsidiary of HN Inc. co.

PRINTING TECHNOLOGY PRIMER FOR BUILDINGS
The Russian College of Engineering and Technology at Ohio University presents real-world methods in “Guide to 3D Printed Buildings: Materials, Tips and Resources Required” as part of an overview of the master’s degree in civil engineering, posted under Engineering and Technology Degrees at https://onlinemasters.ohio.edu. The guide provides an overview of the 3D printed buildings; labor saving project planning and benefits; challenges in adopting the molding / manufacturing method; and construction-grade printing materials.

“3D printing technology has had a revolutionary impact on businesses around the world. It allows companies to rapidly develop models and prototypes, thereby accelerating their ability to test and refine new products. It also makes it easy and affordable to manufacture parts and components that keep important machines running as intended, ”the guide’s authors explain. “One of the most interesting applications of 3D printing technology is in the construction industry, where it is used to build entire houses, office buildings and other structures. 3D printed buildings can span thousands of square feet and multiple floors, and they can be manufactured with lower costs and less waste than buildings of traditional construction. [They] represent one of the most important construction and design trends for civil engineers. “

The authors describe the basic process flow: 3D printing uses large-scale machines in which an engineer enters floor plans and building designs, and operators feed ink for concrete or others. printable building materials; a software-guided extendable arm, or nozzle, then applies the material or mixture in thin layers; The entire building or structure emerges to the engineer’s specifications, one layer at a time. Among the advantages of 3D printing methods: Materials are consumed at exact volume requirements, without waste, as printers can accurately follow dimensions and specifications of the plan.
