In the present study, a new Design for Additive Manufacturing (DfAM) method for hot stamping dies is evaluated, namely lattice structured. In order to evaluate the benefits of the lattice structured method with regards to the thermal performance, a hot stamping die integrated with a lattice structure and a traditional solid die were additively manufactured. The dies were subsequently tested in the hot stamping of AA7075 aluminium alloy blanks under cyclic loading conditions, with the temperature evolutions, of both the blank and die, being presented. The analysis of the results shows that the lattice structured method has considerably improved the cooling performance of hot stamping dies.
