The 40ft bridge spans a stretch of water in the Castilla-La Mancha park in Alcobendas, north of the Spanish capital. It may have beaten another 3D printing construction project, a steel bridge coming up over a canal in Amsterdam. After several years of experimentation and testing, the Dutch robotics firm MX3D hopes to start manufacturing the horizontal-structured bridge in the next couple of months.
Meanwhile, the Madrid bridge is made up of eight parts, each one comprising layers of fused concrete pow der micro-reinforced with thermoplastic polypropylene reported The Locale.
“The 3D printed bridge, which re flects the complexities of nature’s forms, was developed through parametric design, which allows to optimize the distribution of materials and minimize the amount of waste by recycling the raw material during manufacture,” said the design team. “It’s a milestone for the construction sector at international level, since, to date, this technology has not been applied in the field of civil engineering.”
