SAE International has released additive manufacturing (AM) polymer specifications for the aerospace industry. AMS7100: Fuse Filament Fabrication Process and AMS7101: Material for Fused Filament Fabrication reportedly represent the first specifications released under the AMS-AM Additive Manufacturing Non-Metallic (AMS-AM-P) committee, according to SAE International. These standards were created after a request from airlines through the International Air Transport Association (IATA)'s EMG…

…performance or spatial requirements, materials, manufacturing methods and cost constraints. Through an iterative process, the software explores all possible permutations and quickly generates several design alternatives, learning what works and what doesn’t from each iteration (Fig. 2). Current use cases have shown that generative design can reduce part weight by as much as 30% using traditional manufacturing and 70% using…

The current capabilities of additive manufacturing (AM) are the result of 30 years of invention and innovation. Yet there is so much about the technology that remains a promise. Currently most 3D printers used for AM can use only one material; a select few can print a product with two materials. The long-term vision for AM materials research is to…

…and aerospace manufacturers turning to additive manufacturing (AM) in their lightweighting projects, the die casting discipline begins to feel its glory days are fading. Some ask: will AM ultimately replace die casting? Others worry that it’s not a matter of “if,” but “when”—that the fate for die casting is sealed. But Dr. Joshua Huang, the senior technical lead at Ryobi…
