“Our goal is to propose an alternative to the current reinforced concrete Liang’s approach,” said José Ramón Albiol of the Polytechnic University of Valencia. “These are using profiles built for length, which require expensive installation and are difficult to transport.”

The team has developed an alternative plan for nearly three years, and has now finalized a design, hoping to accomplish some different things in the construction industry. The system consists of a series of independent fragments that can be 3D printed using recycled plastic, then assembled on site, and concrete is poured on top to form structural beams. The internal composition of these individual segments is inspired by the way the thick and compact human bones are formed, and provide some useful properties for the beam.

“This is what we transferred to these Revolutionary beams, especially their contours,” Albiol said. “This is a very intelligent natural system. Its replication in these beams has a lightweight structural weight and very high mechanical properties.”

According to the team, these beams are 80% lighter than standard concrete beams and have no metal features, which eliminates The risk of corrosion is reduced. More importantly, their 3D printing properties are suitable for easy customization, and the beams can be customized to the necessary dimensions for the job at hand.

Team member Miguel Sánchez said: “In order to be able to customize the beams on site, it is possible to adapt the characteristics of each beam to the structural requirements of each construction site.”

The team has applied for a patent for the new design of its structural beam, hoping to Technology commercialization.
