3D printer with residual material infrared detection and alarm functions

Abstract

The invention discloses a 3D printer with residual material infrared detection and alarm functions. The 3D printer comprises a printer body and a residual material monitoring mechanism arranged on theprinter body, wherein the residual material monitoring mechanism comprises a detection body, an alarm, an infrared detector and a controller. A channel penetrates through the detection body from topto bottom. The inner of the detection body is provided with the infrared detector, and the infrared detector is installed inside a print head. The inner of the detection body is further provided witha power supply, a first switch and a second switch. The power supply, the first switch, the second switch and the alarm are electrically connected in sequence to form a circuit. When two oppositely-arranged conductive detection blocks abut against together, the second switch is closed, otherwise, the second switch is disconnected. The 3D printer with the residual material infrared detection and alarm functions can automatically monitor the surplus of printed wire during using, and give an alarm when the residual materials are insufficient or the printed wire is broken, thereby reducing the workload of operators.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer with infrared detection and alarm for excess material. Background technique [0002] FDM desktop 3D printer is a kind of machine that does not rely on laser as the forming energy, but heats and melts various wires (such as PLA polylactic acid, ABS engineering plastics, PC polycarbonate, etc.) and accumulates them into shapes. Use the computer-aided design (CAD) function to create a 3D model that needs to be printed, and save the model in stl format; then use the CURA software to slice the 3D model data to generate corresponding motion instructions, thereby instructing the printer to fuse the filament At the same time, under the control of the computer, the print head selectively coats the material on the workbench according to the information of the cross-section profile, and forms a layer of cross-section after rapid cooling. After one layer of molding is compl...

Problems solved by technology

[0003] During the printing process, if the remaining material is insufficient, the printing will be interrupted halfway, which will seriously affect the continuity of the printing work, and the printer will continue to work and cause all the original printed products to be damaged.

At present, operators are usually required to watch in real time and replace them in time when the remaining materials are insufficient, which seriously wastes manpower and increases the workload of operators.
