Research on Cutting-Bonding Process of Powder Based 3D Printing Model

摘要

Powder based 3D printing technology is one of the few full color 3D printing technologies, which is widely used in customized model and packaging industry, and has been gradually applied in the manufacturing industry of medical model. In the process of printing large-size model and repairing damaged model, cutting-bonding is an essential step. In this paper, the maximum tension of standard model, the cutting angle of test model, the type of adhesive and the effect of temperature on the properties of the adhesive were studied. It was found that the bonding effect was positively related to the smoothness of cut surface. The adhesive with strong stickiness and transparent color was more suitable for powder based model. The bonding strength increased with the increase of the adhesive temperature and 45 °C was the best bonding temperature of powder based model.
