Material feeding method for 3d printer, and related device

A 3D printer, wherein the 3D printer is configured to be connected to an automatic feeding system provided with a plurality of material troughs, and the 3D printer is configured to perform a material replenishment method for a 3D printer, wherein the 3D printer is configured to be connected to an automatic feeding system provided with a plurality of material troughs, and the material replenishment method comprises:

• acquiring attribute information of the printing materials provided in all material troughs of the automatic feeding system, and obtaining the at least one material trough set based on the attribute information of the printing materials;
• displaying at least one material trough set, and display the replacement relationship of each material trough in the said material trough set;
• wherein each of the at least one material trough set comprises at least two material troughs, and a replacement relationship exists between the material troughs within each material trough set;
• the said replacement relationship is used to indicate the material trough that shall replace it for printing when the printing material in a certain material trough is exhausted;
• and
• the at least one material trough set comprises a first material trough set;
• and if a printing material in a first material trough within the first material trough set is detected to be used up, replacing, based on a replacement relationship between the material troughs within the first material trough set, the printing material in the first material trough with a printing material in a second material trough within the first material trough set for printing.
