About Arena Națională
In Bucharest, Romania, Arena Națională (the National Arena) is a football stadium with a retractable roof. The earlier National Stadium on the same site was torn down from 2007 to 2008, and the new arena opened in 2011. At 55,634 seats, no stadium in Romania is larger, and the arena hosts home matches of the Romania national team.
Gerkan, Marg and Partners designed the stadium, and the firms Max Bögl and Astaldi built it. The roof covers the playing surface and takes 15 minutes to open or close. The decision to add the roof, worth €20,000,000, was made on October 8, 2009. The stadium was inaugurated on September 6, 2011, with a UEFA Euro 2012 qualifier in which Romania and France drew 0–0 in front of 49,137 fans.
Atlético Madrid and Athletic Bilbao met at the arena in the 2012 UEFA Europa League final. The arena also hosted four games at UEFA Euro 2020. One of them was a Round of 16 match in which France and Switzerland drew 3–3 and Switzerland won 5–4 on penalties. In October 2021 it hosted The International 2021, the Dota 2 world championship. Concerts there have featured Ed Sheeran, Depeche Mode, Metallica, Guns N' Roses and Red Hot Chili Peppers.

- A ring of slim columns
- The outer wall is a dense ring of thin vertical columns. Print friendly adapts them to the print scale; Full detail keeps every column, which suits a larger print or a fine nozzle.
- Thin radial roof ribs
- The roof is a ring of fine ribs that fan out around the central opening. A bigger print size keeps them distinct, and layers of 0.12 to 0.16 mm keep their edges crisp.
- One piece with the ground
- Arena Națională is joined to the ground in the exported file, and the four-side check found no floating parts, so nothing needs gluing.
- Pick the detail for your nozzle
- In the Buildings settings, set Landmark detail to Print friendly to adapt thin parts and small details to the print scale. Full detail keeps every modeled feature, for larger prints or a finer nozzle.
- Colors

- File format
- You get a 3MF for Bambu Studio, OrcaSlicer or PrusaSlicer. Any of them can save it as STL if you need one.
