Abstract
A printing head module and a three dimensional (3-D) printing apparatus using the same are provided. The 3-D printing apparatus includes a base and the printing head module. The printing head module is disposed above the base and includes a printing head and at least one material spool. The printing head includes a plurality of assembling pieces assembled with each other to form the printing head and define a nozzle of the printing head. Each of the assembling pieces includes at least one material-supply groove. The material-supply grooves of any two adjacent assembling pieces are located corresponding to each other to form at least one material-supply channel together. Each material spool is connected to the material-supply channel for providing at least one fluid material to the material-supply channel. The fluid material is transmitted via the material-supply channel to be dispensed on the base.
