 D printers usually operate with a single material, but are made from many different materials.  So a self replicating 3D printer (a self replicating machine) would need to be a number of printers, each processing one of the required materials.  3D printers also usually produce parts, rather than entire mechanisms, so self replicating 3D printers would also require a robotic assembler.  Most 3D printers also produce parts that do not have the required surface finish and precision for final operations.  So some kind of surface finishing tool, such as Computer Numerical Control (CNC)  machines, would be required to finish shafts and rolling parts to adequate tolerances.  So a Self replicating 3D printer would in fact be more like a small factory, capable or producing each of the different parts of the factory and then assembling them into a second factory.  So it might be fairly massive and complex.  Such a self replicating machine has been speculated upon for a number of decades and may eventually be produced.  See Wikipedia; [[w:Self-replicating_machine#cite_note-40|Self replicating machines]] for extensive references.
