3D printers are <i></i>part<i></i> of the future of manufacturing, but hardly all of it. I think it's more like computer inkjet printers once were. Sure, 20 years ago they were rare and novel, but now everyone can have one if they want. They never ended up being the future of the printing industry. They're for home users to do a few things with, but will never replace or play a serious part of production for commercial printers of books, magazines, photos, etc. Any serious office has a much more expensive laser model that a hobbyist couldn't afford. This is all fine-people are now able to print off a few photos, documents, flyers to post around and more. An inkjet doesn't replace a book printer and binder machine anymore than a small fused deposition modeler (3d printer) replaces a CNC lathe or casting furnace. They have different roles and that won't change.<p>Not be negative, but I see a lot of hype and I don't think all of it is warranted.
