The invention relates to steady, reliable and intelligentized 3D printing equipment. The steady, reliable and intelligentized 3D printing equipment comprises a support seat, a top plate, a first support rod, a printing head, a vertical movement mechanism, a plane movement mechanism, a first support mechanism, a second support mechanism and a voice control module. The vertical movement mechanism comprises a first motor, a worm, a first worm wheel, a second worm wheel, a first lead screw, a second lead screw and a support plate assembly. The plane movement mechanism comprises a second rotating shaft, a third motor, a third gear, a fourth gear and a linear displacement assembly. In the steady, reliable and intelligentized 3D printing equipment, the suspended type plane movement mechanism is located at any point inside a horizontal plane through polar coordinates; the vertical movement mechanism is combined with the plane movement mechanism, and 3D printing is achieved; in a voice controlcircuit, the specification of an integrated circuit U1 is TDA1521, the output power of the integrated circuit U1 is high, and reliable output of voice signals is guaranteed; and in addition, the 3D printing equipment has the overheating and overload short-circuit protection function, and thus reliability of a system is improved.
