AI Technical Summary

Benefits of technology

This technology helps prevent any remaining printed material from sticking around or getting stuck inside other parts during production by removing excessive fibers with an immersion liquid called melted water. By doing this it prevents damage caused when small particles get trapped between moving components like bearings used for movement. Additionally, the use of specific properties such as density and viscosity can help improve the quality control process through monitoring how well each part works over time.

Problems solved by technology

The technical problem addressed in this patents relates to improving the quality of thermal fusion type 3D printer's used during production processes such as resin transferring process. Specifically, existing methods involve removing excessive printing plugs through manual labor which adds extra steps and costs.

Embodiment 1

[0029] A method for removing residual printing filament according to the present invention is specifically a method for removing residual printing filament in the nozzle when the FDM printer is powered off for printing or printing is suspended, such as figure 2 shown, including the following steps:

[0030] S1. When receiving a request for reprinting, the nozzle of the printer leaves the original printing position and moves to a predetermined initial position. The predetermined initial position in this embodiment refers to a position avoiding the printing platform.

[0031] S2. The printer executes the instruction of heating the nozzle, the nozzle is heated to the temperature required to melt the printing filament, and then executes the first filament feeding instruction, the heated nozzle melts the residual printing filament in the melting chamber, and the first feeding The printing filament pushes the remaining printing filament out of the melting cavity. Then execute the sec

Embodiment 2

[0045] An FDM printing device, using the method for removing residual printing filament as described in Embodiment 1.

[0046] As a preferred embodiment, the FDM printing device further includes a nozzle assembly, a heating assembly and a filament extrusion assembly.

Embodiment 3

[0048] A storage medium, the storage medium includes a stored program, wherein the method for removing residual printing filament described in Embodiment 1 is executed when the program is running.

[0049] For the purposes of this specification, a "storage medium" may be any device that can contain, store, communicate, propagate or transmit programs for use in or in conjunction with instruction execution systems, devices or devices.

[0050] The storage medium described in this embodiment may be a computer-readable signal medium, a computer-readable storage medium, or any combination of the above two. More specific examples of storage media include at least (non-exhaustive list) the following: electrical connection with one or more wiring (electronic device), portable computer disk case (magnetic device), random access memory (RAM), read-only memory (ROM), erasable editable read-only memory (EPROM or flash memory), fiber optic devices, and portable read-only memory (CDROM).

Abstract

The invention discloses a method for removing a residual printing wire, a FDM printing device, a storage medium and a processor. The method for removing the residual printing wire comprises the stepsthat when a request for reprinting is received, a spray head leaves an original printing position and moves to a predetermined initial position; an instruction of heating the spray head is carried out, the spray head is heated to the temperature required to melt a printing wire, and then a first wire feeding instruction is carried out, and the first incoming printing wire extrudes the residual printing wire out of a molten cavity; then a second wire feeding instruction is carried out, and a second input printing wire extrudes a melted printing wire from the molten cavity after the first wire feeding; a pumpback instruction is carried out, and the printing wire is raised reversely; and a third wire feed instruction is carried out, a third input print wire begins to fill the molten cavity, and the spitting wire automatically falls from a nozzle. The residual printing wire is removed by using the characteristics of molten fluid and the gravity action, the molten cavity is filled, the residual printing wire not flowing out of the nozzle after reprinting is ensured, so that the scrapping of printed parts is avoided, and the qualified rate of products is improved.
