Counterintuitively, 2D printers are substantially more complex than 3D printers. Everything inside them needs very tight tolerances and many thousands of custom components. The only companies that have the tooling to make printer-specific parts are printer manufacturers and they sure aren't going to sell you parts so you can directly compete with them.
