Abstract

The applicability of plastic tools additively manufactured by fused deposition modelling for sheet metal forming processes was evaluated. Aluminium and steel sheets were V-bent and deeply drawn with the plastic tools. The dimensional accuracy of bent sheets with the plastic tools was lower than that with steel tools due to low stiffness, and deteriorated with increasing flow stress of a sheet. The stiffness was increased by reinforcing the plastic tools with steel bars, and thus, the dimensional accuracy of the bent sheets was improved. Not only springback of the sheet but also elastic deformation of the plastic tools was successfully corrected by modifying the shapes of the tools. In addition, the deep drawability of a cylindrical cup with a plastic die was examined.
