9. piezoelectric three dimension printing shaping as claimed in claim 1 system; It is characterized in that; Said 3 D-printing formation system also includes automatic control device; This automatic control device is used for dividing the unifications such as motion control, vacuum extractor and temperature control on layer scattering, the three-dimensional to control to the 3-D view of whole 3 D-printing formation system operating process, realizes the unmanned formula work to whole 3 D-printing process thus.
10. any described system of use such as claim 1-9 carries out the method for 3 D-printing moulding, and this method comprises:
The 3-D view that divides layer scattering mechanism will need moulding through 3-D view is separated into a series of continuous two-dimensional sheet images with certain bed thickness;
Under the drive of motion (11), shop powder mechanism (20) promotes to transfer to forming cavity (17) with the dusty material of corresponding height from said powder storing chamber (13) successively according to the floor height that said 3-D view divides layer scattering mechanism to set at X;
X is brought into shower nozzle (10) to motion (11) print area of die cavity (17) top; And according to the two-dimensional sheet image information drive piezoelectric type shower nozzle (10) along X to moving; Said piezoelectric type shower nozzle (10) self along perpendicular to the Y of X-direction to moving and optionally spraying solution as binding agent, thus according to two sheets dimension image information with the dusty material molding bonded;
X returns initial position to motion (11) and bearing structure (21), prepares the printing of next two-dimensional sheet image, repeats above step then and so circulates, and all prints completion up to all two-dimensional sheet images.
