At present, additive manufacturing technology for non-metallic materials (mainly organic polymer materials) has been relatively maturely applied. However, in the additive manufacturing of metal materials, due to the high melting point of the material, high viscosity and surface tension, and some metals are also highly corrosive, there are still many technical problems to be solved in terms of how to improve the forming accuracy, performance and efficiency of the formed parts.
