Thanks for bumping this thread, I hadn't read it till now.
3D printing and other "personal manufacturing" technologies are going to create an interesting future for us all. There'll be a point where it'll sweep through both the small inventor and modeller space ... then expand, as technology permits, to places we can't today imagine.
The world of copyright is also going to get smashed.
Take a little example ... imagine the tiny plastic figures used on some of the strategy board games ... then imagine cheap bulk 3D print material from China with appropriate 3D print data to make them
I can't wait for the technology to be cost viable - but I don't think any of us truly understand the changes it could bring about.
Consider a continuous length 3D printer, capable of producing decorative cornice or skirting ... all of a sudden your profiles can have complex multidimensional surfaces ... the can be customised for corners, etc. We're standing on the very tip of the iceberg!
Agreed. One of the "biggies" I think is work that has been done on a large 3D printer that extrudes concrete..... to print houses.
I'm hanging on to my 3D printing stock options.
