Research on 3D Printing Process of Metal Powder Based on UV Curing

[摘要] In this paper, the 3D printing process of metal powder based on digital micro jet was studied. This process used a UV resin with a fast curing speed and high strength as a binder to realize rapid metal powder molding. The influence of process parameters such as nozzle temperature, print pitch, powder coating thickness and printing speed on the forming quality of metal powders was analysed. The adhesion of UV resin and metal powder was obtained by electron microscope. By measuring the density of the model and combined with the molding effect of the model surface, the better process parameters were determined. The results showed that under these process parameters, the bonding effect of UV resin and metal powder can be improved, and the error of molding process can be reduced. It has some theoretical and experimental significance for metal ink-jet printing technology.
