The invention relates to an automatic material switching device for 3D printing and a 3D printer. The automatic material switching device for 3D printing comprises a switching mechanism, a first driving mechanism and a material box mechanism. The switching mechanism comprises a reversing shaft and a plurality of reversing wheels, and the reversing wheels are spaced in the axial direction of the reversing shaft and distributed in the circumferential direction. The reversing shaft is driven by the first driving mechanism to rotate by the preset angle, so that the at least one reversing wheel moves to the transmission position, the reversing wheel located at the transmission position is in transmission connection with the winding disc, accordingly, the consumable wound on the winding disc is subjected to discharging operation, and the consumable of the corresponding color or material can be extruded out. The reversing shaft is driven by the first driving mechanism to rotate by different angles, so that the rever
