Additive Construction – The Path to Standardization Continues

The National Institute of Standards and Technology (NIST) Engineering Laboratory (EL) Materials and Structural Systems Division (MSSD) studies the durability and service life of infrastructure materials (polymer, concrete, engineered composites) for resilience infrastructure applications. One of the key research focuses is the development of Additive Construction methods, materials, and measurement requirements. Additive construction by extrusion (ACE) has the potential to revolutionize construction by complimenting the existing workforce, eliminating the need to construct formwork, and enabling architectural or structural designs that cannot be achieved by standard practices. As ACE has progressed over the past few years, the development of standards has lagged, and the need has become essential to promote industry and ensure safe structures. NIST has the unique opportunity to aid in the development of measurement science tools and a scientific knowledge base to support the industry’s needs for performance-based standards for 3-D printed concrete structures. As a result of the unique identity of this workshop format, the event has gained popularity and continues to grow with increased global interest throughout the industry. The event, Additive Construction – The Path to Standardization Continues, builds on previous engagements, with this year's workshop will include presentations, breakout sessions, networking events including an evening dinner, tours, and a poster session all directed toward the current state and desired future state for the additive construction industry, R&D needs, timelines, and action items. Topics will focus on the development of codes, standards, and design guidance, materials and testing methods related to additive construction and the needs of the industry with respect to education, safety, and field vs. laboratory implications.
