The market growth trend of Metal Powders for Additive Manufacturing (and special applications, as HIP and MIM) is particularly important and promises to keep strong in the next years, especially for the ceaseless expansion of the main Additive Technologies (AM first) and the consolidation of many industrial solutions in different application fields (e.g. aerospace, energy, automotive, biomedical).
In addition to new 3D printing technological solutions, able to increase productivity, costs reduction and components dimensions, an increasing number of new market demands are from new materials for AM, as proprietary solutions for specific applications and final properties, able to get the best from the competitive values promised by the new Additive Technologies. All the main sector indicators and specialist reporting are pointing to the same direction, i.e. the combination of these two main development directions to be the cornerstone of a rapid, robust and clean growth of this certain leading actor of Industry 4.0.
Answering this complex demand, Numanova S.p.A. has identified and selected productive technologies believed to be nowadays the best to provide the most complete and affordable answers to these needs. All production processes and their own technologies available in Numanova S.p.A. are able to offer the widest chemical and morphology solution range, thank to a unique combination of operation flexibility, consolidated technologies and internal know-how in the Powder Metallurgy for AM applications.
Furthermore, an important competitive factor is represented by constant and continuous in-house efforts in R&D and Innovation for products, processes and technologies, as distinctive element and basic asset of company’s commitment towards customers and shareholders to become a market leader.
