Prague has the world's first 3D printed parkour playground

Prague – On the last day of September, a ceremonial opening of the first 3D-printed parkour playground took place at the Kupeckého recreational area in Prague 11. This is a joint project of the Building Society of Česká spořitelna, the company 3Deposition, and the Prague 11 municipal district. The playground is patroned by parkourists Tomáš Zonyga and Daniel Samek, who is also the author of the playground's design. Besides parkour training, the elements can also be utilized for general movement development or bodyweight strengthening. The playground project has received the patronage of Zdeněk Hřib, the Mayor of Prague, Jiří Dohnal, the Mayor of Prague 11, and the Czech Parkour Association.

The advantage of the printed playground is the absence of sharp edges, and thanks to the use of poured rubber as a landing surface, its safety is at a high level. The playground is designed to facilitate movement development and inspire new challenges for all levels of advancement. It is intended for everyone aged 10 and above (up to 15 years with supervision). Younger children may be on the playground, but due to height differences, most elements are intentionally inaccessible to them.

The playground has a circular footprint with a diameter of 14 m and contains fourteen 3D-printed elements interconnected by steel pipes. To increase strength, the individual walls are filled with recycled concrete rebetong and reinforced with shaped steel reinforcement. All 14 elements of the playground were printed on a frame printer by the spin-off company 3Deposition, founded by experts from the Faculty of Mechanical Engineering at the Brno University of Technology. The printing, which took 10 hours of pure time, required 12.5 tons of special concrete mix.
