In advanced R&D, "good enough" doesn't cut it. To pioneer its Performance-Aided Design (PAD) workflow, Autodesk Research partnered with Markforged to close the gap between digital simulation and reality. Using sensors and digital twins, PAD replaces delayed field reports with real-time feedback. To test this high-stakes system, Autodesk built massive UAV platforms -- including a 300-lb aircraft. Facing extreme dynamic loads and weather, these drones provide the ultimate torture test for rapid design iteration.

Radio Flyer cut prototype lead times for its Flyer Loop cargo ebike frame from two months to two days using Formlabs' new Fuse X1 SLS large-format 3D printer. "We can now print an entire Flyer Loop cargo ebike overnight and be gluing it together the next day," said Agostino LoBello, product development engineer at Radio Flyer. "I can iterate three times as often with nine times less labor." The Fuse X1 delivers production-quality parts with 50% lower costs and triple the throughput of comparable industrial systems, featuring automated powder handling and a compact, easy-to-install design.

One of the primary benefits of using a coiled spring pin to affix a hub or gear to a shaft is the coiled pin's ability to prevent hole damage. Another is the coiled pin absorbs wider hole tolerances than any other press-fit pin. This translates to lower total manufacturing costs of the assembly. However, there are a few design guidelines that must be adhered to in order to achieve the maximum strength of the pinned system and prevent damage to the assembly.

In the early 1990s, scientists at GE Global Research came up with a tough new material that could outperform super-alloys used to make jet engines, and was also one-third lighter. Since weight cuts fuel use, shedding pounds is always a big deal in aviation. But the team faced a skeptical crowd.
The material was a form of ceramics, which can take a lot of heat but have been known to break on impact. "All the lab test showed it was as durable as metal, but people had questions about using it inside an engine," says materials scientist Jim Vartuli, one of the lead researchers on the project. "Now, with almost one million hours of testing, including more than 15,000 hours in land-based gas turbines that are actually generating electricity, the questions have been answered. This material is ready for flight."
GE spent the last two decades developing the next-generation material, called ceramic matrix composites (CMCs). It is strong, tough, and also amenable to mass production. CMCs are made from silicon carbide matrix toughened with coated fibers made from the same material. They are already working inside CFM's new LEAP jet engines and advanced gas turbines. The material is light, one-third of the weight of nickel super-alloys, but extremely durable. It can work in temperatures as high as 2,400°F, well beyond any advanced alloy.
"Silicon carbide is fantastic," Vartuli says. "It is the lightest and strongest material that can work at high temperatures. But if you make a coffee mug out of it, it will break when you drop it." That's where the fibers with GE engineered coatings come in. They make CMCs behave like a metal when they're hit. "There's no concern about catastrophic failure," Vartuli says.
Being both tough and light is a powerful combination. "If you take a pound off something that's spinning, you get a whole cascade effect," Vartuli says. "That pound works out to be usually about three additional pounds you can take off from the support structure and bearings because of a smaller centrifugal force."
As a result, airline customers can keep their lighter planes flying longer between engine check-ups, add new globe-spanning routes, and save millions in fuel costs. But CMC applications reach beyond aviation. GE is already testing CMC parts in gas turbines for power generation. Why? Just one percentage point in added efficiency saves millions in fuel costs annually, and reduces emissions thousands of metric tons of CO2.
