<p>PROBLEM TO BE SOLVED: To provide a 3D printer which allows quick change of constituent materials different in characteristics.SOLUTION: A 3D printer includes a base, a print head, a plurality of material supply spools and a changeover unit. The base has a conveyance surface. The print head is arranged over the base. The individual supply spools each contain a constituent material, and the constituent materials are mutually different in characteristics. The changeover unit is configured so as to connect at least one of the material supply spools selectively to the print head. The constituent material of the selected material supply spool is distributed to the conveyance surface by the print head.</p> |
