We see 3D-printed architecture all the time now, but then Czech Republic-based organization Buřinka thought outside the box and literally took 3D printing outside to create a parkour playground!  The 3D-printed parkour playground is the first of its kind constructed from recycled concrete and other eco-friendly construction materials. Parkour is the activity or sport of moving rapidly through an area, typically in an urban environment, negotiating obstacles by running, jumping, and climbing so the structure was made to be durable and resistant to urban climate. Buřinka also made the country’s first 3D-printed house, is adding to its list of 3D construction innovations with a new project. This is a joint project between the private sector, the public sphere, and research ventures. Spanning 14 by 12 meters in size, the parkour playground uses cast rubber for the impact area with individual obstacles made of concrete. Obstacles are printed on a frame printer with materials from Master Builders Solutions CZ to highlight safety and strength. The foundations are printed out of recycled concrete, known as rebetong, in collaboration with researchers from the Brno University of Technology. The playground, which is designed by Buřinka architect Daniel Samek, is set to open at the end of September 2021 and will be included in the new leisure area at Kupecký Elementary School in Prague. Samek said he was drawn to the project for its accessibility, as parkour doesn’t require any expensive equipment and can be enjoyed by both children and adults. “The playground that is now being created is unique in that it works with rounded shapes,” said the architect. “It brings a revival to parkour.” In an industry facing many challenges, such as worker shortages and rising building materials, Buřinka maintains that robotics and 3D printing could provide necessary solutions among Czech construction companies. “Housing does not mean just four walls,” said Libor Vošický, Chairman of the Board of Directors of Buřinka. “It is also essential to have a possibility to spend free time outdoors, safely, close to home. There are many playgrounds for preschoolers, but older children don’t have many options, so we decided to use innovative 3D printing technology to create a parkour playground. At the same time, we want to confirm the benefits of using recycled concrete called rebetong. It is another milestone in the use of this innovative technology.”
