This reminds me of TerraFab (http://terrafab.bengler.no/). A Norwegian site where users can zoom in on norwegian fjords, and press the order 3d print button.
Edit: Someone has put up the Terrainator site (https://terrainator.com/) that generates 3D print files from Google maps. It costs money and you have to 3d print the thing yourself.

fantastic! anyone have sources for USA lidar point clouds?
In related projects, this script takes a GeoTIFF (which usually comes from a lidar pass) Digital Elevation Model, and renders it inside minetest (opensource voxel game).

There are a few solutions much better than the old tech used by meshlab.
Specifically, fssr[0], which does a more advanced and especially sample-density-compensating variant of meshlab's poisson reconstruction, as well as instant meshes[1], which does generic retopo, and is able to handle point clouds, while still being _very_ fast and delivers surprisingly good low-poly results (see for yourself).

Haven’t printed anything yet, but the STL loads great into a slicer (I used cura) of your choice.

Kinda hard to use, though. You can find the raw data by state here: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/NED/LPC/projects/
1.1 trillion points online and growing.
