Not to mention that many printed docs are expected to have a relatively short life span. Handouts for a meeting, shopping lists, address labels, etc. For the person printing things on the average "cheap" printer, they're not typically concerned with the longevity aspect. Most 3D-printed things seem to be the opposite for mainstream applications. People keep using examples of printing "stuff you can't get at Walmart" and implying the printed parts are expected to be used for many years in an environment that will have some moderate amount of wear and tear. 3D printing not only needs to get faster by an order of magnitude, the quality of the output component needs to increase substantially as well. You need to be able to print in colors and wind up with a finished product that looks close to the quality of an injected molded piece.
