Research on the Anisotropy of Mechanical Properties of Powder-Based 3D Printed Models After Dipping

Powder-based 3DP (3D printing) is an emerging molding technology that has the characteristics of low energy consumption, low cost and no exhaust gas emissions. It has been rapidly developed in the creative and customized industries. However, the mechanical properties of its products depend on the feasibility of full-color large-size 3D printing models. Based on the anisotropy of the mechanical properties of 3D printing and the characteristics of impregnating agents that will enhance the mechanical properties of post-printing models, this paper studies the mechanical properties of powder-based 3D printed components under different dipping methods and different cutting angles, combined with the surface structure characterization, and selects the best parameters to maximize the strength of the components before bonding. The results show that the ColorBond impregnated samples show excellent mechanical properties, which can reduce the surface roughness, weaken the step effect, make the powder-based model have the strength of the functional model, and reach the maximum value when printed at a 45° angle to the Z axis.
