Abstract
A forming tool including an additive manufactured polymer shell defining a first side and an opposite second side. The forming tool includes a support structure mechanically connected to the second side of the shell. The support structure may be formed by pouring a molten backfill material into the shell, and solidifying the backfill material. The backfill material includes a low melting temperature metal, fusible alloy, or other element. The solidified backfill material has a strength and rigidity greater than the polymer used to make the shell. The first surface of the shell includes a complex surface for bringing into contact with a material in a stamping process to form a stamped part.
