It might be the length of time to print but once started the printer can be left to do its thing.

I would never recommend this on a filament printer.  You pretty much need to keep an eye on them all the time.  Do a quick google for fires started by this type of printer.

The filament printers are slow and take many hours to print.  I think these will start to disappear as resin printers become readily available.  Faster prints and better detail, should drop prices for items created this way.

A good 3d scan is hard to do without going to big budget scanners.  I am playing around with software for this now for converting photos into 3d models, trying to get me a good render of a Chimera 500 I want to build.
