Alcoa is a global leader in light metal technology, engineering and manufacturing, creating a wide range of material solutions for the world, providing value-added products made from titanium, nickel and aluminum, and producing world-class bauxite and oxidation. Aluminum and primary aluminum products. Alcoa's Arconic business map, source: am Just as oil companies like Shell, Mobil, BP, and Chevron have upstream oil and gas exploration and mining operations, and downstream chemicals and lubricants businesses. Now, Alcoa is going to spin off Arconic, a downstream company that will focus on metal powder production, 3D printing , hot isostatic pressing, forging, casting, machining, and quality inspection. In the powder bed selective laser sintering technology, Alcoa has made continuous attempts. In Pittsburgh, Alcoa also has EBAM electron beam melting welding technology to produce large-sized forging metal parts. As early as 2014, Alcoa announced that it would use 3D printing technology to manufacture jet engine parts, because Alcoa found blades such as jet engines, which were manufactured in a traditional way from design to finished product for about a year, using 3D printing. Technology, time can be reduced to just 25 weeks. In addition to reducing the time by more than half, the cost of new product development may be reduced by 25% compared to traditional processes. And the three-dimensional modeling process allows the design of complex components to be turned into reality, which shortens the lengthy development process. Alcoa EBAM equipment, picture source: am In fact, the nature of raw materials directly affects the quality of metal 3D printing products, and Alcoa has invested a lot of manpower and material resources in this area. Alcoa engineers have clearly understood that different metal printing equipment is more suitable for processing metal powders of different types, and in the actual processing process, how to achieve the optimal setting of processing parameters to make the desired products, This involves the control of the geometric geometry of the product and the control of the material melting process, and achieving such a subtle level of control requires extensive experimental verification and strict operational discipline.

They not only have an understanding of additive manufacturing based on a large number of operational practices, but also include post-treatment processes such as hot isostatic pressing. A lot of investment has been made. Alcoa's own capabilities can be used to control every step of the additive manufacturing process, and they can even develop specific metal powders based on specific processing needs and then manufacture them through additive manufacturing processes. Post-processing and quality testing. Airbus is one of Alcoa's current major customers, and Alcoa offers a package of services from materials to finished products. Alcoa has invested more than $20 million in Whitehall, Michigan, to improve the thermal isostatic pressure on 3D printed metal parts.

It is clear that Alcoa places great emphasis on the industry market prospects surrounding additive manufacturing. Alcoa believes that additive manufacturing can create complex geometries compared to traditional manufacturing, which makes many traditional manufacturing methods impossible, and highlights the advantages of additive manufacturing. However, complexity is not the most important, and for users, they want parts that are lighter, stronger, more fatigue-resistant, and less susceptible to damage. Metal 3D printing makes products by rapid crystallization of metal powders, which makes it particularly important to control the level of crystallization. Alcoa's proprietary "Ampliforge" process is an example that combines both forging and additive manufacturing processes. In this process, the blanks are first made by additive manufacturing and then post-treated by forging. Of course, the preform requires only one forging in this process, rather than 11 or 12 times in a typical forging process. Through such a processing method, this part actually becomes a forging. Not only is it because of its own core technology, but another reason why Alcoa has split Arconic is to meet all market needs, not just the rapid growth of demand for additive manufacturing in the aerospace industry, including the automotive industry. The demand in the field of sporting goods is also becoming increasingly prominent. Although the current focus on metal 3D printing is focused on the aerospace and medical fields, Alcoa also attaches great importance to other fields. Alcoa believes that the design optimization for aerospace core components usually lasts for 7 years, while the parts optimization for formula cars Sometimes it can be as short as 8 weeks. Alcoa does not believe that aerospace is the most mysterious industry in the application of additive manufacturing technology. The most mysterious industry is the consumer sports industry. Alcoa's approach can be described as a comprehensive network, with a focus on training. Indeed, the current stage of 3D printing is quite similar to the feeling of the development of the western United States. Each company has different views on the potential and prospects of this technology, but the consensus is that you must understand the entire process chain. Only by averaging the entire process chain, you can get a learning curve that is ahead of others at every point, and leading means competitiveness.
