Following this thread and the one about the 3D printed SBC have been very interesting. Perhaps its time to look at building a printer. One question I am curious about would be printing a body (shell) - does it have to be separated into segments, or can it be printed as one piece? The ones that really should pay attention to this are AMT and Revellogram. The could save a ton on tooling costs by investing in the highest spec printers possible, create better detailed parts and even allow for customers to submit their own custom print files! We could have show cars, race cars, limited interest subjects and more. (Looking at CGTrader almost knocked me out of my chair) The economies of scale could reduce costs of production tremendously by having resin and other material bought in quantity.
