<p>PROBLEM TO BE SOLVED: To provide a print head module which allows simplification of the production process and further reduction of production costs and a 3D printing apparatus using the print head module.SOLUTION: A 3D printing apparatus includes a base and a print head module, and the print head module is arranged over the base and includes a print head and at least one material spool. The print head includes a plurality of assembly parts which are assembled mutually to form the print head and define a nozzle of the print head as a whole. The individual assembly parts each contain at least one material supply groove. Material supply grooves of two adjacent assembly parts are arranged so as to correspond to each other and form together at least one material supply path. The individual material spools are connected to the material supply path and provide at least one fluid material to the material supply path. The fluid material is transmitted through the material supply path and distributed to the base.</p> |
