Alcoa, Pittsburgh, is investing $60 million in its R&D center to accelerate the development of advanced 3D-printing materials and processes. Its Ampliforge process combines advanced materials with additive and traditional manufacturing processes. For example, Alcoa engineers could design and 3D-print a nearly complete part, then increase the strength of the final part with a traditional manufacturing process such as forging.
The company says that the process can enhance the properties of 3D-printed parts by adding such properties as higher toughness and strength, versus parts made solely by additive manufacturing. Furthermore, the Ampliforge process is said to significantly reduce material input and to simplify production compared with traditional forging processes. Alcoa is piloting the technique in Pittsburgh and Cleveland.
Alcoa will produce materials designed specifically for a range of additive technologies to meet increasing demand for complex, high-performance 3D-printed parts for aerospace and other high-growth markets such as automotive, medical, and building and construction. The $60 million expansion is under construction at the Alcoa Technical Center near Pittsburgh.
Alcoa’s materials scientists will produce proprietary aluminum, titanium, and nickel powders designed specifically for 3D-printing. These powders will be tailored for various additive manufacturing processes to produce higher-strength 3D-printed parts, and to meet other quality and performance requirements.
With the industry’s longest-running history of certifying aerospace components and qualifying processes, Alcoa will use its testing and process control expertise to overcome challenges with certifying new 3D-printed parts, starting with aerospace applications.
Construction of the new facility is expected to be completed in the first quarter of 2016. The project will create more than 100 full-time positions—including materials specialists, design experts, and process and inspection technologists—by 2017, and approximately 45 temporary jobs during construction.
