A light network
For the new Výstaviště tram stop in the Prague 7 (Holešovice) district, Czech company So Concrete examined the force lines of the structure and developed a construction that was so efficient that it saves 60 % of the material used with conventional methods. “With the help of topological optimization, it is then possible to reduce the volume of material used”, explains Záviš Unzeitig, a designer with So Concrete. “The result is a perforated fine structure that can withstand the same load as a solid concrete slab."
Parametric design
A bench and information boards will eventually be added to the tram stop. The canopy and bench were made using a 3D robot printing process, but were constructed differently. For instance, only the canopy features steel-fibre reinforcement.

For So Concrete, one thing is clear: the combination of topological optimization, which saves at least half the material, ultra-high performance concrete (UHPC) and 3D robot printing is absolutely a future-oriented technology that will save time and material alike. In fact, the basic structure was ready after only one day.

An optimized structure
The tram stop was constructed in Grasshopper (Rhino) with a view to the characteristics of UHPC. The aim was to create self-supporting structures with as little steel as possible. Thanks to robot-supported 3D printing, even complex shapes were created without formwork. “As we concentrated on developing client-specific digital solutions, we were quickly able to adapt to many different standard file formats and geometry types”, says Dimitry Nikitin, a robotics engineer at So Concrete.
