Numerous methods of 3D Construction Printing have begun to be developed by organizations globally in the last few years for manufacturing houses, footbridges, and other relatively small structures. RCAM Technologies is developing Reinforced Concrete Additive Manufacturing methods for manufacturing mega-scale and highly loaded structures such as ultra-tall wind turbine towers, wave-energy devices, industrial applications, and civil works.

One of the first applications for concrete additive manufacturing was for very low cost residential houses in developing nations. Behrokh Khoshnevis’ at Countour Crafting Corp and the World Advanced Savings Project (WASP) have pioneered the development of technologies for these markets. In recent years, tens of public and private organizations across the globe have begun …
Founded to develop concrete additive manufacturing technologies initially for wind energy technologies. The company’s vision for wind energy is to develop land-based and offshore wind turbine towers and substructures up to 250-m tall at half the cost of conventional tall tower technologies. RCAM Technologies’ team, partners, and advisors have been carefully selected to provide world-leading expertise in key disciplines needed to dominate industrial concrete additive manufacturing markets.

C.P. (Sandy) Butterfield
Founder and President of Boulder Wind Consulting. Sandy has been an innovator and leader in wind energy his entire career. Prior to founding Boulder Wind consulting Sandy co-founded Boulder Wind Power, a startup company that developed an innovative direct drive generator technology. He led Boulder Wind Power through its formative stages as CEO, helping to raise $48 million to develop its radical direct drive technology. Prior to that he spent over 24 years at the National Renewable Energy Laboratory (NREL), most recently as Chief Engineer at NREL’s National Wind Test Center and leader of the Gearbox Reliability Collaborative. Prior to NREL he co-founded ESI, a wind turbine manufacturing company in 1980. His work at NREL included aerodynamics research, testing, design reviews, contract management, manager of the applied research program and leader of the certification / standards program. Sandy was chair of IEC TC88 and is currently Chairman of IECRE the IEC Renewable Energy Conformity Assessment System (www.IECRE.Org ). He still serves on several IEC international standards committees. LinkedIn
Mo Li, Ph.D.
Professor in the Department of Civil and Environmental Engineering, and the Department of Chemical Engineering and Materials Science at the University of California, Irvine (UCI). She received her Ph.D. from the University of Michigan, Ann Arbor. Her expertise is in advanced and multifunctional materials and structures, concrete additive manufacturing, fracture mechanics, distributed sensing method, and industrial ecology. She also has 15 years of experience with engineered cementitious composites that feature extraordinarily large tensile ductility. She directs the Advanced Infrastructure Materials Manufacturing and Research Laboratory at UCI, and has access to the UCI Large-Scale Structural Testing Hall. She has served as principal investigator for a number of federal-, state- and industry-funded research projects, including three DOE projects that focus on innovative concrete technologies, advanced manufacturing and monitoring methods for energy-related applications.
