Can 3-D model buildings, such as those by RenderHub and 3Dmodels.com, be printed out with a 3D printer? How is this done?

One of my hobbies as a teenager and young adult was model railroading. It eventually became too expensive for me, but I spent a lot of time building highly detailed craftsman model kits, and could build whole city skylines out of plexiglass and paper.

In more recent times, in need of ruined, abandoned buildings, I turned to gaming sites such as various wargames and Minecraft, in search of suitable structures, and stumbled upon the plethora of highly detailed 3D models that’s out there.

As many of you know, I’m dumb. But can these things be printed out with a 3-D printer?

I realize some of these buildings are extremely large and detailed, such as entire cities, rocket launch stations, and olympic stadiums. But what about the simpler houses, warehouses, apartment buildings—maybe even some of the skyscrapers?

I am a pretty good model builder, the old-fashioned way—but I am really excited about the possibilities if I could work with 3-D modeling and print them out, and assemble them if so required, and paint them if need be.

Can these 3D structures be printed out with a 3-D printer as scale models, or must they stay in the world of virtual gaming?

If so, how is printing such structures done?
