Description
Technical Field
The invention belongs to the field of additive manufacturing. In particular to an additive manufacturing method for constructing a three-dimensional ordered structure.
Background
The additive manufacturing technology represented by 3D printing is a new manufacturing technology that uses a computer graphics file as a base to continuously superimpose specific materials layer by layer to form a three-dimensional structure entity through fused deposition modeling, laser irradiation and other modes. The traditional machining and manufacturing technology has the advantages of long machining period, complex process, high cost and high product rejection rate, and the additive manufacturing technology has outstanding advantages in the aspect of quick and accurate forming and can directly convert the design idea into the required three-dimensional structure, so that the additive manufacturing technology is widely concerned by people in recent years. The 3D printing is a typical representative of the additive manufacturing technology, the typical process selection of the 3D printing and the selection of the corresponding processing materials are closely related, the specific processing and manufacturing process is only suitable for the corresponding materials, and the specific processing materials can be realized by utilizing the specific 3D printing processes. Therefore, the selection of printing process and processing materials are two of the most important factors in order to limit the development of 3D printing technology at this stage.
The existing additive manufacturing technology usually needs to adopt specific instruments and materials and processing technologies aiming at specific materials, and the processed and manufactured products have single material and function. For example, for a high polymer material, the existing 3D printing technology needs to obtain a three-dimensional structure through a stereolithography technology or a fused deposition modeling technology, which are difficult to implement for processing a metal material; in the case of metal materials, a high-energy laser device is generally used to obtain three-dimensional metal components by a selective laser melting sintering technique, and this processing method causes carbonization of polymer materials. In practical application requirements, such as high-end manufactured products such as high-performance three-dimensional components, tissue engineering scaffolds and the like, diversification of materials and chemical components of the products is often required, and good composition among different materials is expected to be realized. At present, for most 3D printers with only a single feeding system, it is difficult to realize additive manufacturing of three-dimensional structures of different materials, and it is difficult to further realize good compounding and stable compounding among different materials. Meanwhile, compared with the traditional manufacturing technology with relatively low processing equipment and processing raw materials, the equipment and the consumable price used in the existing additive manufacturing technology are generally high, and the popularization is not facilitated.
Therefore, developing an additive manufacturing method with high universality and low price solves the additive manufacturing problem of three-dimensional ordered structures of multiple materials and multiple chemical components, and becomes a great challenge in the development of additive manufacturing technology.
The present invention has been made to solve the above problems.
