Before 3D printers, there were 2D printer. It's a great invention that brought an end to the book manufacturing industry (publishing, printing and distribution) because people could now print 2D based products from the comfort of their home. The machine used simple materials such as paper and coloured ink and could transform them into book and magazine, given the proper blueprints which you can buy from the Internet.
There might even be 3D blueprints to create such a machine
