Embodiment Construction

[0065] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0066] Such as figure 1 , figure 2 As shown, the specific process of making multiphase material parts layer by layer by droplet jetting is as follows:

[0067] The 3D CAD model of the 3D structure to be processed is designed by a computer with high-speed computing capabilities. According to the functional requirements of the part, the material design of the 3D CAD model is carried out, that is, the material is represented by color, and then the CAD entity slice is divided into three parts. layer, forming a series of two-dimensional slices containing structural information and material information. The thickness of each slice can be the same or different, and the thickness of each slice is 1 μm-300 μm. The computer 11 controls each mechanism to perform coordinated movements according to the forming information of each layer. Specifically, when the p...

Abstract

The invention discloses a molding method of components of heterogeneous materials, comprising the following steps of: establishing a CAD model of a three-dimensional body, carrying out variegation on the CAD model, then carrying out discretization slicing delamination to obtain a series of two-dimensional slices with material information and structure information, converting the structure information of each slice into corresponding digital control processing programs, realizing precise accumulation of molding materials of each separated layer by digital control motion and opening and closing of a nozzle, accomplishing microdrop accumulation of the material of the layer according the above method under the control of control processing program of corresponding layer; spraying propping materials for padding, as propping, in areas of each layer which are not sprayed; bonding and overlaying layer by layer to produce the designed three-dimensional body finally; removing padded propping materials of each layer to obtain three-dimensional molded parts containing heterogeneous materials corresponding to computer solid models. The invention can produce heterogeneous materials and functional components with high molding precision and strength quickly, the process is simple, the production cost is low, and the choice of materials is wide.

Description

technical field [0001] The invention relates to a molding method of a three-dimensional structure part, in particular to a molding method for manufacturing a three-dimensional part containing multiphase materials layer by layer by means of droplet jetting. Background technique [0002] High-performance functional parts containing multi-phase materials have broad application prospects in functional devices, micro-aircraft structures, and load-bearing parts of space power systems in military, aerospace, and nuclear industries due to their unique physical and mechanical properties. and value. [0003] If the preparation of this kind of multi-phase material parts adopts traditional preparation methods such as chemical vapor deposition, electrolytic deposition, and plasma spraying, because the position of each material phase cannot be accurately controlled, only a material model with a relatively simple shape can be prepared, and it cannot be directly prepared. Parts of complex ...
