New method of making models for the..........I'll leave that one open to your thought's.

After visiting the blog, it

After visiting the blog, it looks as if they completely rebuilt the 3D model from scratch.  So the laser scan is apparently just used as a reference.  If you can find decent 3-view drawings, you can accomplish the same thing.

3D printing a chimney?

Isn't one of the major expenses in developing a 3D model the creation of the software to do the printing,.....research, drawings, etc ??

Can such a job be shortened considerable in time an expense by just scanning an original object to create the program to print out a copy??

Indeed.  There's quite a bit of this going on in the construction industry already; I worked on a power plant construction where the HVAC supplier came in with a laser scanner to model the interior of the high bay area.  Saved them a lot of time measuring, and relying on possibly incorrect drawings.

However, at this point it's not the panacea you want in your assertion.  Well, depending on the detail you require...   scanning with today's tools might not give you the resolution you want for things like filigree.  Hmmm....  Thinking aloud, printing all the structures for a scene from low-res scans might be a viable "style"...

  Surely it's already being done for modelling purposes?  Aren't Modelu doing so with some of their figures?  They are doing so in the UK anyway. One can have oneself scanned and printed by them, then you're immortalised on your model railway!
   Surely there must be someone doing so that side of the pond??

I’ve done a lot of scanning using iPad/iPhone apps for work and also done couple of scan-to-print “tests”. For organic shapes the scan to print pipeline is very fast and requires minimal cleanup.   Polycam is the app we use professionally in combination with a LiDAR-equipped phone. I think I posted some images somewhere else (blogs?) but here are some again. The printed model is 1:48.

I should add that you don’t need a LiDAR-equipped phone to get good results, the sample above was done without LiDAR using an iPhone 8!

I know Bernard Hellen of miniprints (https://www.miniprints.com/) does 3-D scans of people and prints them, don't know how many of these are real people, but do know some are:  https://www.miniprints.com/shop-people/ Also he has scanned people on demand at the Great Scale Model Train show in Timonium, MD and is going to do the same at the Amherst Society Model Railroad show at the Big E in Springfield, MA (https://www.miniprints.com/springfield/)

EDIT: After poking around the site discovered this page:  https://www.miniprints.com/minimes/
