Rob, I'm no car expert. But the one farthest in front, as far as I can tell, in using new non-battery materials and assembly technologies is Ford. A few others I'm aware of are Daimler Benz, Audi, Lamborghini, BMW and various EWV makers. Regarding batteries and their materials, Chuck would be your best source.

Ann, that's interesting that some automakers are more likely to adopt cutting edge technology than others. Care to name names? I'm under the impression that Ford and VW are ahead, but I'm out of my depth here. I may just be responding to press releases.

Jim_E, yes we've come a long way from those early experimental days. Plastics aren't what they used to be, especially since we got engineering-grade polymers.

As a "motorhead", I'll always remember the "plastic" timing gears that Cheverolet used in their small black V8's in the 1970s.  Ugh!  They had a tendency to wear and break, and we always replaced them with real metal gears.

We've hopefully come a long way from those days.

jmiller, thanks for your comments. I've been surprised at what a difference the materials can make between metal and plastic in so many details of the part design. And I agree about a materials company working with engineers to figure out better designs, and therefore, more appropriate materials. I think that's growing.

notarboca, I think one reason why plastics have beat out aluminum--once they can meet the specs--is because all polymers are custom, by the nature of their manufacture. That means that, within certain spec parameters, you're more likely to find the right combination of properties for a specific app. Another reason may be price. Aluminum is still very expensive, at least compared to steel.

For me one of the most interesting parts of the process is how the design has to be adjusted for alternative products.  Sometimes it's fins for strength, attachment points or any other number of reasons that before the part couldn't be made from plastic.  Now with a little innovation and asking the right questions, the design can be totally improved.  Definitely cool.

In my opinion the auto industry has been the leader in stepping out and trying to create something new.  I think it helps that everyone needs a car and we as Americans buy so many.  There are dollars all around to support this innovation.

I like it when a raw material company comes in and tries to create a market for their parts by working with the engineers to adjust the design of the parts to fit their materials.

This article made me think about some of my past designs and how critical material selection was up front.  Sometimes we know it's going to be metal and other times plastic may be the way to go.  Either way, you need to know what you're doing before you spend too much time designing all the connections and geometry for the part.

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.
More and more -- that's what we'll see from plastics and composites in 2015, more types of plastics and more ways they can be used. Two of the fastest-growing uses will be automotive parts, plus medical implants and devices. New types of plastics will include biodegradable materials, plastics that can be easily recycled, and some that do both.
