The invention provides a delta type five-degree-of-freedom 3D (Three Dimensional) printing machine and belongs to the technical field of digitalized processing. The delta type five-degree-of-freedom 3D printing machine is used for solving the problem of gravity limitation caused by a cantilever and a hollow structure in workpiece design engineering and can be used for directly printing a free curve-surface structure so as to improve the quality of a printed piece and the efficiency of 3D printing. According to the delta type five-degree-of-freedom 3D printing machine, a spraying nozzle movement mechanism forms movement in XYZ directions by adopting three groups of parallel rod mechanisms under the action of a stepping motor and a synchronous belt; meanwhile, a printing platform movement mechanism provides movement of overturning around the X axis and/or the Y axis for a printing platform, and five degrees of freedom are formed; in a printing process, a supporting material or a supporting structure, which is n
