The utility model discloses a material breakage detection device and a 3D printer. The device comprises a feeding module, a consumable channel and a detection cavity are formed in the feeding module, and a through hole communicated with the detection cavity is formed in the consumable channel; the shielding piece is arranged in the detection cavity and is movably arranged in the through hole; one end of the elastic piece is connected with the shielding piece, and the other end is fixed in the detection cavity; the emitter and the receiver are respectively arranged on two sides of the shielding piece and are fixed in the detection cavity; when a consumable passes through the consumable channel, the consumable extrudes the shielding piece to the outer side of the through hole so as to shield the space between the emitter and the receiver. And when the consumable channel does not have consumables, the shielding piece is bounced away from the space between the emitter and the receiver and returns into the through
