Sylvain Dehaudt, enriched with two decades of experience at CERIB following a background in precast and Ready Mix Concrete (RMC), and holding a PhD in Civil Engineering, has overseen various projects focused on concrete formulation and industrial processes. Currently, he is concentrating on industrial property and the valorization of the center's innovations. Since 2017, his interest has particularly been on 3D printing.
CERIB is a Technical Industrial Center (CTI), a hub for research and innovation. Its expertise in the construction domain, particularly in the concrete industry (materials and precast products), along with its cutting-edge equipment, allows it to support industrialists and market specifiers by providing technical support and information. CERIB is engaged in major challenges such as decarbonization and the circular economy, especially focusing on the recycling of aggregates in concrete construction products. These efforts are bolstered by the acquisition of the MiniPrinter Pro, a 3D printer developed by Constructions-3D, which enables CERIB to familiarize itself with this technology and explore its potential applications.
The collaboration between CERIB and Constructions-3D began with the specific design of the MiniPrinter Pro to meet CERIB's needs. This initiative has allowed CERIB to offer training, manufacture prototypes, and most importantly, work on the characterization of printed materials.
3D printing meets the need to create products with non-traditional geometries and allows for freedom from constraints such as formworks and curing times. Sylvain Dehaudt emphasizes that, despite regulatory and technical hurdles, 3D printing offers a unique ability to enhance and diversify existing production methods.
In the long run, 3D printing could play a crucial role in decarbonizing and preserving natural resources within the construction sector. The MiniPrinter Pro enables CERIB to develop characterization tests on printed concrete, essential for the future certification of printed precast products.
"The decision to collaborate with Constructions-3D was based on their expertise and their ability to meet the specific technical requirements of CERIB." For companies considering adopting 3D printing, Sylvain Dehaudt recommends approaching experienced players to benefit from their insights and experience. "
CERIB remains at the forefront of innovation, with ongoing projects on 3D printing and a continuous commitment to decarbonization. A working group is being formed to establish recommendations on the use of 3D printing, underscoring its essential and growing role in the precast industry.
The collaboration between CERIB and Constructions-3D exemplifies how strategic partnerships can accelerate the adoption of innovative technologies while addressing contemporary challenges in the construction industry.
