The utility model provides a delta type five-degree-of-freedom 3D printer, and belongs to the technical field of digital processing. The problem of gravity limitation caused by a cantilever and a hollow structure in workpiece design engineering is solved, a free-form surface structure can be directly printed, and the quality of a printed piece and the 3D printing efficiency are improved. Accordingto the utility model, the nozzle movement mechanism adopts three groups of parallel rod mechanisms to form movement in X, Y and Z directions under the action of a stepping motor and a synchronous belt; meanwhile, the printing platform movement mechanism provides movement of overturning around the X axis and/or the Y axis for the printing platform; and the supporting materials or supporting structures which have five degrees of freedom and are not beneficial to post-processing in the machining process in some design workpieces can be reduced or eliminated by controlling the platform to inclinein the printing process, and the printing precision and the printing efficiency are improved.
