The prospects of 3D printed plastic tooling in the processing of metal forming are shown. The study of the process of thin sheet, forming of aluminum 3003 ANSI, established that in this process the destruction and plastic deformation of the plastic tool does not occur. Lubrication of plastic matrices and punches were not required, as they have anti-friction properties. Computer simulation of this process in the software system "Simufact.forming" accurately reflects the force parameters, stress-state of plastic tool and the actual course of the process of forming the blank, including the spring-back of the part after forming. Technology of sheet forming with plastic tool can be recommended for single and small batch production.

The paper deals with the problems and prospects of forming thin-sheet blanks, using ABS plastic dies, made by 3D printing. This technology combines the positive properties of plastic material and 3D-printing. The mechanical characteristics of the plastic were determined experimentally. On the basis of computer modeling, the dependence between the angle of bending the blank and the stresses arising in the dies is established. As a result of computer simulation and physical experiment, the value of the maximum thickness 0.5 mm for the aluminum 3003 blank is obtained. In this case, there is no plastic deformation of the plastic tool. The use of plastic dies does not require lubrication. The technology of sheet bending, using a plastic tool, can be implemented with the greatest efficiency in single and small-scale production.
