Abstract
A 3D printing filament feeding apparatus for feeding a filament () includes a primary driving wheel (), a secondary driven wheel (), a measurement scale rotating disk (), an optical sensor () and a cleaning assembly (). The primary driving wheel () is connected to a power source () and driven thereby to rotate. The secondary driven wheel () is arranged adjacent to and parallel with the primary driving wheel (). The measurement scale rotating disk () includes scale structures () and rotates together with the secondary driven wheel (). The optical sensor () detects the scale structures (). The cleaning assembly () engages with the scale structures (); wherein the secondary driven wheel () engages with the filament () and rotates along a driven direction (D) together therewith such that the scale structures () passes through the cleaning assembly (), followed by detection of the optical sensor ().
