Like engineers using rapid prototyping technologies to quickly print a 3D designed part (using, say, stereolithography). Would be cool to have a whole region with its mountains in 3D laying on your desk

I seriously doubt that GoogleEarth imported prototype programming into its output. It basically uses the same technology as Flash. It’s not really sending a 3d image. It’s sending an extended 2d image which means it’s got several flat layers that move at different speeds as you move across the landscape. But that would be incredible wouldn’t it. First thing I’d print would be the Peak of the Himalayas

The technology

Starting from a 3D image, a part is built slice by slice from bottom to top, in a vessel of liquid polymer that hardens when struck by a laser beam.
Schematic overview of the stereolithography process

Starting from your STL file, the required supports for overhangs and cavities are automatically generated in the model under construction. The support and model files are then “cut” into thin horizontal slices and programmed into the stereolithography machine.

This machine then uses a computer controlled laser to draw the bottom cross section onto the surface of a liquid polymer that hardens where struck by the laser. The part is then lowered to a depth corresponding to the section’s thickness and the next cross section is then drawn directly on top of the previous one. This is repeated until the part is finished.

TransMagic STL PRO is a 3D CAD data repair and exchange software application designed specifically for medical, digital manufacturing, rapid prototyping (RP) and 3D printing industries. Anyone needing to use STL (stereolithography) files can:
- VIEW a wide variety of native and neutral 3D files without CAD software or licenses.
- REPAIR geometric errors to create water-tight solid models.
- TRANSLATE models to accurate STL files for rapid prototyping, tooling and manufacturing.

It’s easier to repair a CAD model than an STL file!
