[Abstract]:Fiber reinforced polymer (FFP:FRP-FDM-3DP) is the leading technology of 3D printing. It can effectively improve the intensity and accuracy of FDM forming 3D printing products, and enhance the application scope of products. Although FFP has many advantages, but there are some key problems, such as: no specific FFP special wire extrusion equipment; powder reinforced effect is limited, continuous fiber reinforced material drawing phenomenon, not easy to traction and cutting, unable to print complex parts and hollow parts; the problem of low work efficiency. On the basis of the study of the key equipment of FFP, this paper focuses on the research of the equipment for the manufacturing of short cut fiber reinforced composites by molten deposition and deposition. The main contents and conclusions are as follows: (1) the development of 3D printing special wire extrusion equipment for micro low consumption short fiber reinforced composites by melting deposition molding. The extrusion molding principle combined with 3D printing special wire extrusion die was used to develop the micro FFP special wire extrusion equipment. It is used to prepare 3D printing special wire for fiber and resin reinforced composites with different kinds, specifications and content. (2) the development of multi head high efficiency FDM 3D printing equipment. In order to improve the efficiency of 3D printing work, the production mode of low cost and multi head high efficiency printing with 3D printing technology is put forward. According to the principle of fused deposition modeling design of multiple print head 3D printer, and is compared with a single print head 3D printer, long 3D printer results of this design can complete, 3-5 times to improve work efficiency and equipment utilization rate of finished products, print production work quickly. (3) the application of 3D printing technology for melt deposition of short fiber reinforced composites is introduced in the case of a case. In this paper, fifth sets of RMB coin sorting machines developed by the team are used as a case to introduce the application of 3D printing technology for short fiber reinforced composites.
