The invention discloses a 3D printing machine with an inclinable working platform, and belongs to the technical field of digital machining. The 3D printing machine is a five-shaft linkage 3D printing device based on a parallel mechanism. The working platform is inclined through electric push rods and spherical hinge structures; and the electric push rods are hinged to a lower platform adopted as a static platform of the parallel mechanism through hooke joints to form a 3-PRS parallel mechanism. According to the 3D printing machine with the inclinable working platform, the defects of a traditional two-shaft or three-shaft linkage 3D printing machine are overcome, the printing efficiency is greatly improved through five-shaft linkage, the gravity limit problem caused by a cantilever and a hollow structure during workpiece design engineering is solved, hollow polyhedrons, multi-layer honeycomb structure workpieces and curved surface workpieces can be directly printed through the 3D printing machine, and the 3D p
