I should probably make it clear I'm not looking to build a home or hobbyist 3d printer. I'm interested in building a high volume production machine. I'm having difficulty getting good information on that type of 3d printer, and what kind of components I need to acquire. From my experience in CNC machines, usually your money is best spent on the actual business end components, and not the R&D involved in designing the gantry, and other structures. For example, most large production CNC machines are built by the machine shops that run them for cost reasons. You end up with a higher quality machine. At the moment, I'm assuming this is also the case for 3d printers, but that's why I'm here.
