Description

3D printing methods, systems, electronic devices, and storage media Technical Field This application relates to the field of printing equipment, specifically to a 3D printing method, system, electronic device, and storage medium. Background Technology 3D printing technology is an additive manufacturing technology, and there are various types of printers available. Currently, the most commonly used type is based on the Fused Deposition Modeling (FDM) process. The working process of this type of printer involves feeding material into a cartridge, melting the filament into a liquid state using high temperature, then extruding it through the print head and allowing it to solidify. Finally, the filament is arranged in three-dimensional space to form a physical object. The cartridge is one of the most important components of a 3D printer, playing a crucial role in the printing effect and is one of the core devices in 3D printing. In related technologies, during the 3D printing process, an extruder is used to drive the filament into the print head, and then the molten filament is extruded from the print head for printing. However, during the printing process, there may be situations where the filament needs to be changed. Existing methods require operators to stay by the printer for a long time to manually change the filament. If the filament tray is not changed in time, the printing will fail, which greatly reduces work efficiency and filament utilization. Summary of the Invention In view of this, this application proposes a 3D printing method, system, electronic device, and storage medium that can effectively improve the material changing efficiency of the printer. In a first aspect, this application proposes a 3D printing method applied to a 3D printing system, the 3D printing system including a printer and at least one consumable storage device, the printer including at least one material guiding device and at least one nozzle assembly; the 3D printing method includes: acquiring printing information, the printing information including a consumable printing sequence; controlling a first nozzle assembly to print using a first consumable based on the consumable printing sequence; controlling the next second consumable required by the first nozzle assembly to be transferred from the first consumable storage device to a first branch channel of the first material guiding device based on the consumable printing sequence; responding to a first material changing command, controlling the first nozzle assembly to return the first consumable to a second branch channel of the first material guiding device; and, after detecting that the first consumable has returned to the second branch channel, controlling the second consumable to be transferred from the first branch channel to a first main conveying channel of the first material guiding device, so that the first nozzle assembly can print using the second consumable. Compared with related technologies, the embodiments of this application have at least the following advantages: Initially, the printer's printhead assembly extrudes the second consumable for printing. When the printer needs to switch to the first consumable for printing, a material change command is sent. In response to the material change command, the printer selects the first consumable storage device containing the first consumable and controls the first consumable to be transferred from the first consumable storage device to the first branch channel. Simultaneously, the printer controls the first printhead assembly to stop ejecting the currently printing second consumable and controls the second consumable to be transferred from the first printhead assembly through... The main conveyor channel transmits the material to the second branch channel. At this time, the first consumable is transferred from the first branch channel to the main conveyor channel so that the first printhead assembly can spray the first consumable. By setting up a main conveyor channel and multiple branch channels that converge on the main conveyor channel, when the printer receives a material change command, the first consumable to be replaced can be transferred to the first branch channel in advance. When the printer detects that the second consumable being printed has returned to the second branch channel, that is, when there is no second consumable in the main conveyor channel, the first consumable is directly transferred from the first branch channel to the main conveyor channel. This method allows the first consumable to be transferred to the first branch channel in advance without waiting for the second consumable to completely return to the second consumable storage device, thereby greatly shortening the transmission time of the first consumable and improving the printer's material change efficiency. In some embodiments, the 3D printing system further includes a second filament storage device, and the printer further includes
