Abstract
A material filling apparatus for 3D printing fills materials into a material tank by a feeding part and includes a fixed sleeve with a first open end and a fixed end connected to the feeding part, a moving sleeve movably inserted and tightly fitted and interfered with the fixed sleeve, and a material output pipe inserted into the moving sleeve. The material tank is movably sheathed on the material output pipe. The moving sleeve has a second open end and a blocking end. The material output pipe has a connecting end and a material output end. The blocking end blocks the rear end of the material tank. The material tank squeezed by the filled material moves the connecting end towards the material output end and the rear end away from the material output end to push the blocking end and move the moving sleeve together with the material tank.
