Abstract

The invention discloses a piezoelectric-type three-dimensional printing forming system and a forming method thereof. The system comprises a box body and a supporting framework thereof, an X-direction movement mechanism (11), a bearing structure (21) which is connected onto the X-direction movement mechanism, a powder storage cavity (13), a forming cavity (17), a three-dimensional image layering discrete mechanism, a powder pavement mechanism (20) and a piezoelectric-type spray head (10), wherein the powder storage cavity (13) and the forming cavity (17) are arranged below the bearing structure, and the powder pavement mechanism (20) and the piezoelectric-type spray head (10) are loaded on the bearing structure (21). The piezoelectric-type spray head can spray a solution without heating the solution, so that more varieties of solutions can be sprayed, and the piezoelectric-type three-dimensional printing forming system can be applied to the emerging fields such as biology, pharmacy and the like. Caking ingredients can be mixed into powder through the system, so that sufficient caking ingredients can be added to achieve satisfactory caking strength. In addition, the piezoelectric-type three-dimensional printing forming system has advantages of compact structure, simpleness in operation, low equipment expense and high forming precision.

Description

technical field

[0001] The present invention relates to the technical field of three-dimensional printing molding, and more specifically, to a piezoelectric jetting three-dimensional printing molding system and a molding method thereof. Background technique

[0002] 3D printing rapid prototyping technology was first developed by Emanuel Sachs of Massachusetts Institute of Technology and others. It is currently one of the most vital technologies in the field of rapid prototyping and has broad application prospects. This technology is a growth-oriented manufacturing technology based on the idea of ​​"discrete / stack". It uses computer technology to discretize the 3D CAD model into a series of 2D cross-sectional views in one direction, and then prints and accumulates them layer by layer according to the information of the cross-sectional views. In each layer of printing, the precision nozzle is used to spray the bonding solution on the pre-laid powder plane to bond the powder in...
