What do US military planners consider top materials research targets? Well according to the head of the Pentagon’s research arm (the Defense Advanced Research Projects Agency or DARPA) low-cost titanium tops the list. Titanium is in increasing demand for light weight aircraft and stealth-seeking submarines, while its costs are rising and significant amounts of supply are controlled by Russia. One troubling indication is the recent huge supply agreement made between Boeing and Russia’s top titanium provider. DARPA has distributed more than $20 million in grants in efforts to develop lower-cost titanium, as well as material that would have improved fabrication capabilities. DuPont is teaming with a company called MER to explore a technology in which titanium dioxide can be converted into titanium power which can be easily shaped through molding or casting processes.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
3D printing, 4D printing, and various types of additive manufacturing (AM) will get even bigger in 2015. We're not talking about consumer use, which gets most of the attention, but processes and technologies that will affect how design engineers design products and how manufacturing engineers make them. For now, the biggest industries are still aerospace and medical, while automotive and architecture continue to grow.
