[Abstract]:According to the characteristics of high efficiency and wide adaptability of the prototype of melt deposition forming (FDM) process, a method of prototype manufacture using low temperature metal instead of thermoplastic material is put forward. The characteristics of melt deposition molding process with low temperature metal as materials and the influence of various process parameters on the quality of deposition molding were investigated. On this basis, a low temperature metal 3D printing system is developed. Sn99.3Cu0.7 wire is used as the material in the experiment. The experiments of monolayer deposition and multilayer deposition are designed and implemented. The experiment proves that the monolayer wire and 3D metal model with good quality can be obtained by optimizing the motion parameters of low temperature metal 3D printing system. The feasibility of application of low temperature metal melt deposition forming process in PCB plate making and three dimensional metal forming is verified. According to the experimental results, the problems that should be solved in the following technical development are put forward.
