Additive Manufacturing Biomedical Components Heat Management Munitions Propulsion Radiation Management


In recent years, metal additive manufacturing has evolved beyond rapid prototyping applications and is now used to manufacture a range of complex, high-performance engineering components. AM techniques are supremely versatile: as well as providing a means to produce geometrically complex pieces, they can provide an economic route for lower volume products and dramatically improve material utilization in expensive materials.

With AM technology improving rapidly, the pool of possible AM applications increases every day. H.C. Starck Solutions refractory metal powders are currently used to produce components for biomedical, propulsion and heat management systems, among others.
