TC4 material has good comprehensive mechanical properties, but its development is limited due to its complex preparation process and high cost. Three-dimensional printing forming technology has the characteristics of low cost, wide range of materials, fast forming speed, etc. In this paper, the binder and powder formula of 3D printing molding process were studied. According to the viscosity value, surface tension, bonding effect and the service life of nozzle, the optimal formula of binder was selected. Finally, according to the formulation of binder and mixed powder, TC4 blank was prepared by 3d printing machine, TG-DSC curve of PVA and starch was analyzed, degreasing sintering process was designed, degreasing and sintering of TC4 porous material was carried out. Finally, the performance of the parts under different time - aging treatment is studied.
