Abstract
A feed detection apparatus of a 3D printer, comprising a gear, a measurement device, a support, and a compression assembly. The gear is provided on the support to abut against a filament material, and rotates along with a movement of the filament material. The measurement device is placed on the support to measure a rotating speed of the gear, and determines a feeding status of the filament material according to a measurement result. The compression assembly comprises a connection member and an abutment member; the connection member is provided between the support and the abutment member; the abutment member is used for regulating a pressure of the connecting member applied on the support so as to enable the gear to abut against the filament material.
