Abstract: A switching device for a printing mode of a 3D printer, wherein the switching device includes: at least two handpiece guiding parts (110), each handpiece guiding part (110) is provided with at least one handpiece body (100), and the handpiece body (100) is capable of moving along a length direction of the handpiece guiding part (110); at least two platform guiding parts (210), each platform guiding part (210) is provided with at least one platform body (200), the platform body (200) is capable of moving along a length direction of the platform guiding part (210), and the length direction of the handpiece guiding part (110) and that of the corresponding platform guiding part (210) are disposed in a staggering manner; at least two handpiece transmission mechanisms (120), wherein the handpiece transmission mechanism (120) is connected to the handpiece body (100) through handpiece clutch mechanism (130); a handpiece drive mechanism, wherein the handpiece drive mechanism drives all of the handpiece transmission mechanisms (120) to move synchronously; at least two platform transmission mechanisms (220), wherein the platform transmission mechanism (220) is connected to the corresponding platform body (200) through platform clutch mechanism (230); and a platform drive mechanism, wherein the platform drive mechanism drives all of the platform transmission mechanisms (220) to move synchronously. The switching device can implement copy printing, mirror printing, and independent printing.
