About Milan Cathedral
Milan Cathedral, known in Italian as the Duomo di Milano, is the cathedral church of Milan, in Lombardy, Italy, and the seat of the city's archbishop. Its dedication is to the Nativity of St. Mary. Archbishop Antonio da Saluzzo began construction in 1386, and the final details were finished in 1965, so the work stretched across nearly six centuries. No church in the Italian Republic is larger, although St. Peter's Basilica, which is bigger, lies in the State of Vatican City. Milan Cathedral is also one of the largest churches in the world.
The cathedral stands on what was the most central site of Roman Mediolanum, where the public basilica faced the forum, and Milan's streets either radiate from it or circle it. Before work began, three main buildings, including the archbishop's palace, were demolished. Construction ran under the Fabbrica del Duomo, which was given exclusive use of marble from the Candoglia quarry. In 1488 Leonardo da Vinci and Donato Bramante submitted models for a competition on the design of the central cupola, though Leonardo withdrew his entry. The octagonal cupola was completed between 1500 and 1510.
In 1762 the Madonnina's spire was raised to a height of 108.5 m. Carlo Pellicani designed the spire, and Giuseppe Perego designed the polychrome Madonnina statue that tops it. Milan's climate is damp and foggy, and the statue is so often hidden by mist that the Milanese count a day when it can be seen from afar as a fair-weather day. On May 20, 1805, with his coronation as King of Italy near, Napoleon Bonaparte ordered the façade completed.
How it prints
Make this print opens the generator on a 600 m square around the landmark. Buildings print at close to true scale, so the landmark grows with the print size.

- Many slender pinnacles
- The roof is crowded with thin pinnacles around a tall central spire. Print friendly adapts the thinnest ones to your print scale; Full detail keeps them, best on a large print with 0.12 to 0.16 mm layers.
- Print slowly near the spire
- The central spire is the tallest, thinnest part of the model. Printing it slowly, with good cooling, helps the tip hold its shape.
- One piece with the ground
- Milan Cathedral 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. Milan Cathedral 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.
