The idea is simple. Why could not our retail stores like Clas O offer a 3d printing service. I think it makes sense. People who come there probably have problems a 3d printer could be perfect for.
Also with a printer the store could manufacter parts no longer availible. I believe this is a much easier solution than that everyone has a 3d printer.
Come to think of it. I don’t think 3D printing of repair parts will be the recomended way. Mainly because of safety issues.
For decorations for a wedding maybe a paper 3D printer could work wonders. Just imagine what can be done.
