Applications of laser assisted metal rapid tooling process to manufacture of molding & forming tools — state of the art

Recently, researchers related to the development of eco-friendly molding and forming tools have refocused on the laser assisted metal rapid tooling process to cope the global warming and the resource depletions. The advantageous inherent features of the laser assisted metal rapid tooling process, include an additive proves, switchable supply material and material deposition along an arbitrary trajectory, provide the tool designer and manufacturer with a chance to overcome the limitations of the conventional molding and forming tools from viewpoints of the energy consumption, the environmental impact and the material usage. This paper presents recent researches related to the application of laser assisted metal rapid tooling process to manufacture molding and forming tools. In addition, key technologies of important applications are discussed. Finally, the future issues of the laser assisted metal rapid tooling process related to the development of eco-friendly molding and forming tools are described.
