Abstract
The invention provides an FDM (Frequency-Division Multiplexing) three-dimensional printing material monitoring device. The FDM three-dimensional printing material monitoring device comprises a rotary encoder, wherein an encoding induction shaft is arranged at one end of the rotary encoder; the encoding induction shaft stretches out of a bracket and is not in contact with the bracket; one part, which stretches out of the bracket, of the encoding induction shaft is provided with a friction wheel; a wire pressing wheel is further arranged on the bracket; the friction wheel is parallel to the axial direction of the wire pressing wheel; a gap through which a wire rod can pass is formed between the friction wheel and the wire pressing wheel; and the wire pressing wheel and the friction wheel can rotate synchronously along the movement of the wire rod. Compared with the prior art, the monitoring device has the beneficial effect that when the wire rod is normally fed, the wire rod moves to drive the rotary encoder to rotate through the friction wheel, and a pulse signal is output by the rotary encoder and is compared with a feeding amount of a material needed by printing data to judge whether the feeding of the material is normal or not. Once the material is used up or blocking occurs, the pulse signal of the encoder does not correspond to the printing data. A printing control procedure pauses printing and a phenomenon that a printer idles is avoided, so that the service life of the printer is prolonged.
