In the rapidly evolving world of construction, 3D printing with concrete is emerging as a game-changer, promising to revolutionize how we build and maintain infrastructure. However, the path to widespread adoption is fraught with challenges, particularly the lack of standardized testing, processing, and approval procedures. This is where the work of Ksenija Vasilic, from the German Society for Concrete and Construction Technology, comes into play. Her recent research, published in ‘RILEM Technical Letters’ (International Union of Laboratories and Experts in Construction Materials, Systems and Structures), sheds light on the current state of development and proposes initial steps towards European-level standardization.
Vasilic’s research highlights the potential of digital fabrication with concrete as a resource-efficient construction method, which could significantly contribute to sustainability. However, the absence of uniform testing procedures and processing requirements is a major hurdle. “The complexities, lengthiness, and costliness of current construction processes are hindering the widespread adoption of 3D printing in concrete construction,” Vasilic explains. “Standardization is crucial to promote the quality and reliability of 3D printed structures.”
The energy sector, in particular, stands to benefit greatly from these advancements. 3D printing could enable the rapid construction of energy infrastructure, such as wind turbine bases and solar panel foundations, reducing both time and labor costs. Moreover, the precision of 3D printing could lead to more efficient use of materials, further enhancing sustainability efforts.
Vasilic’s paper identifies gaps in existing standards and proposes initial steps towards European-level standardization. This is a significant step forward, as standardization could streamline approval processes, reduce costs, and accelerate the adoption of 3D printing in concrete construction. “By establishing uniform testing procedures and processing requirements, we can overcome many of the current challenges and pave the way for more widespread use of this innovative technology,” Vasilic states.
The implications of Vasilic’s research are far-reaching. As the construction industry continues to evolve, the need for standardized practices in 3D printing with concrete will only grow. By addressing these gaps, Vasilic’s work could shape future developments in the field, driving innovation and sustainability in the energy sector and beyond. The research published in ‘RILEM Technical Letters’ serves as a critical foundation for these advancements, offering a roadmap for the industry to follow as it navigates the complexities of 3D printing with concrete.
