Abstract
In order to study the performance of 3D printing product, some relevant patents and researches are studied. A simulation approach for the static properties of 3D printing product with clearance bubble is presented. The processing procedure of 3D printing is described and a hierarchical model based on three premises is put forward. Moreover, the static balance model of bubble is proposed and gas equations under different conditions are elaborated. Finally, four simulation experiments are carried out. The compared results show that the properties and lifecycle of 3D printing product can be changed, or even destroyed with the change of external working conditions. The interaction among multi clearance bubbles can lead to more severe damages to the 3D printing product.
Keywords: Clearance bubble, 3D printing product, gas equation, hierarchical model, numerical simulation.
