The new manufacturing technologies of the world are increasingly demanding the design and redesign of new alternative products and processes that can be useful and low cost term. The alternative solution and methodology to innovate in manufacturing processes of incremental sheet metal forming is shown in this paper. Through the methodology Product design specification (PDS) as a practical and effective solution, describes the design step, specific requirements, materials and building process to achieve a device's architecture for a sheet metal deformation by two-point method Die less - DPIF. The selection, simplification and functionality becomes a fundamental objective for design engineers.
