The first tram stop in the Czech Republic made using digital concrete printing was designed and realized as a utilitarian structure with an aesthetic dimension that integrates into the art district of Prague’s Holešovice.
The parametric design of the tram stop utilizes the efficiency of natural solutions, using topology optimization to reduce material usage by up to 60% while maintaining aesthetic and structural requirements. The resulting ribbed structure reflects the real behavior of the construction under load, directly visualizing the forces at play. The finely perforated structure withstands the same load as a solid concrete slab.
The tram stop consists of multiple structural segments, each employing different types of concrete and 3D printing approaches. The roof and passenger bench were produced using robotic 3D printing. The material was selected based on function and structural requirements—while the roof contains fiber reinforcement, the seating does not require it. In producing the column capitals, a robot first milled and printed the molds, into which the final capitals were subsequently printed.
