About Inalpi Arena
Inalpi Arena is the sponsored name of Palasport Olimpico, a multi-purpose indoor arena in Turin, Italy. It sits in the Santa Rita district, within Torino Olympic Park. The arena opened in December 2005 and seats 16,600 when set up for basketball, which makes it Italy's largest indoor sporting arena. It cost €87 million to build for the 2006 Winter Olympics, where it hosted ice hockey alongside the Torino Esposizioni. It stands a few meters east of the Olympic Stadium.
An international competition for the design was won in June 2002 by a team in which Arata Isozaki and Andrea Maffei Associates directed the design. Isozaki signed the final project jointly with Pier Paolo Maggiora of ArchA SpA. The exterior is a strict rectangle of coated stainless steel and glass. Its base measures 183 by 100 meters, and the building is spread over four levels: two up to 7.5 meters below ground and two outdoors, rising up to 12 meters.
Movable and retractable bleachers, a temporary movable deck and adaptable acoustics let the interior change shape for each event. The arena was designed for many kinds of events beyond the Olympics, among them concerts, trade fairs, basketball, ice hockey, curling and volleyball. It hosted the Eurovision Song Contest 2022, with semi-finals on May 10 and 12 and the final on May 14, the first time Turin hosted the contest.

- A grid of small roof details
- Rows of small round shapes cover the flat roof, and the walls carry a fine perforated pattern. Print friendly adapts them to the print scale; Full detail keeps them on a larger print or with a fine nozzle.
- Wide and low
- The arena is a wide, low box, so a larger print size spreads its roof pattern over more space. Layers of 0.12 to 0.16 mm keep the stepped roof edges crisp.
- One piece with the ground
- Inalpi Arena 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
- Buildings, roads, water and ground arrive as separate filament slots in the 3MF. Inalpi Arena takes the building color.
- File format
- You get a 3MF for Bambu Studio, OrcaSlicer or PrusaSlicer. Any of them can save it as STL if you need one.
About this model
Inalpi Arena is one of more than 2,300 landmark models in Mini Skyline. They are made with AI, and each one is checked from four sides in its real surroundings before release. Everything around it is built from OpenStreetMap and Overture map data. If you would rather print the shape from map data, turn off Landmark models in the Buildings settings.
Common questions
Is there an Inalpi Arena STL I can download?
Mini Skyline builds the file for you in your browser and exports 3MF, which every major slicer opens. If you need an STL, open the 3MF in your slicer and export it from there.
How big can I print it?
Any print size from 40 mm across. Inalpi Arena grows with the print: about 5 mm tall on the default 160 mm print. For a model larger than your printer bed, Project Mode splits the area into tiles.
Is it free?
Yes. Generation runs in your browser, with no account and nothing behind a paywall.
