Apparatus is disclosed for printing three-dimensional objects, particularly objects having a substantially spherical shape. A pad is provided for printing by means of pad printing. The pad has a silicon shape with a determined thickness, and is mounted on a hollow pad holder made of an undeformable material which constitutes an isolated space together with the silicon shape. The pad is supplied with compressed air and is connected to a pressure vessel by means of a main element provided therefor through an opening. The apparatus is arranged in open loop, wherein there is provided an additional separate aperture for a separate inlet and outlet of air, with a pressure regulating unit enabling the pressure in the pad to be maintained greater than or at a preset level P. The pressure regulating unit regulates the compressed air which enters the regulator through a supply main. |
