The invention discloses a position feedback system and method based on a fused deposition modeling (FDM) 3D printer. The position feedback system comprises an X-axis detection device and a Y-axis detection device. The X-axis detection device is arranged at the X-axis belt driving end of the FDM type 3D printer. The Y-axis detection device is arranged at the Y-axis belt driven end of the FDM type 3D printer. The X-axis detection device comprises an X-axis coder and an X-axis coupler, wherein one end of the X-axis coupler is connected with a rotating shaft of the X-axis coder, and the other end of the X-axis coupler is connected with a driving shaft at the X-axis belt driving end. The Y-axis detection device comprises a synchronous belt wheel, a center shaft, a Y-axis coupler and a Y-axis coder, wherein the center shaft is sleeved with the synchronous belt wheel, and the synchronous belt wheel rotates with the center shaft synchronously, and the two ends of the Y-axis coupler are connected with a rotating shaft
