The utility model discloses an automatic material supplementing mechanism and a 3D printer, and relates to the technical field of 3D printing. The automatic material supplementing mechanism comprises a hopper, a material groove, a feeding pipe and a buoyancy ball. A feed liquid tank is arranged on the hopper and is used for conveying feed liquid to the hopper. The trough and the hopper are arranged at intervals. A containing cavity is formed in the feeding pipe in a protruding mode, one end of the feeding pipe is communicated with the hopper, the other end of the feeding pipe is communicated with the trough, and the communicating position of the feeding pipe and the hopper is higher than the communicating position of the feeding pipe and the trough. The buoyancy ball is adjustably arranged in the accommodating cavity, the accommodating cavity is communicated with the hopper when the feed liquid in the feeding pipe is positioned below the accommodating cavity, and the buoyancy ball blocks the communication par
