Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to an anti-curing feeding mechanism for a 3D printer. Background Art

[0002] 3D printers are used to print three-dimensional products. Models are created through computer software and then injection molded through 3D printers. New products can be produced quickly, thereby reducing the time and cost spent on mold manufacturing.
