The present invention provides an automatic material changing mechanism of 3D printer, comprising an extruder unit containing an extruder outlet, a driving mechanism that correspondingly connects and transmits itself to a loading unit. The loading unit has multiple loading holes that correspond to the extruder outlet and a transmission route is formed between the adjacent loading holes. The driving mechanism transmits the loading unit along the transmission route to make the loading holes correspond to the extruder outlet. A feeding unit corresponds to the extruder outlet and the loading holes of the extruder outlet, which pushes material towards the extruder outlet. Thereby, the present invention is a modular plugin setting, which can apply to Fused Deposition Modeling, FDM 3D printer and does not need to change the platform design of 3D printer. It can automatically change material based on color or material during the process of printing without having the process of stopping, returning material or other p
