I have always thought of 3D printers as Useless , apart from making parts for other 3D printers. But the wife though it was a good idea, so I thought I'd have a go. So far all I have seen is toys and 3D printer parts made. I am sure I will come up with something one day .
It pretty much depends on your view on plastic objects. Plastic will never match metal in terms of toughness. On top of that, printed parts are printed in layers and small sections where the contact area between two successive layers is small, are prone to delamination. Also, you will have to live with the vertical ridges representing each layer. Overall, you should be able to use printed objects for very many application, or at least give it a try before machining the real part.
