I think these partnerships will happen more as 3D printing/AM moves from a proprietary niche industry to a larger, more open platform marketplace. The formation of the National Additive Manufacturing Innovation Institute (NAMII) is giving this a boost, also.
I agree, Chuck. Looks like the commercial-entity-plus-university combination is increasing in 3D printing/AM R&D research. I think that makes a lot of sense for several reasons: universities get funding they need for practical, hands-on research, companies get access to fine minds, and students get a leg up on learning about what's going on in an industry.
TJ, Actually "replicator" is the perfect word for a macjhine that does the 3D manufacturing process. Fabrication almost always involves cutting up materials to make pieces that are then fabricated into an assembly. BUT the lazy media will undoubtedly come up with a shorter and much less accurate word for it. Just look at that term "apps", which is a lazy way of stating "application program", and you have a perfect example of how dumb lazy-talk can be. Even worse, consider the fact that the original meaning is far removed from the term, so that really people have no idea as to what they really are saying or what it means.
Sorry about the rant, but lazy speech is something that bothers me sometimes.
Mydesign, thanks for your enthusiasm. There's a lot going on with 3D printing of metals, more than most people know, since these companies have been very quiet compared to the hobbyist end machines that use plastics.
TJ, your sci-fi movie scenario sounds just like what NASA envisions--feed everything into it and out comes the perfect replacement part. I'd like to see multi-material (metals + plastic) 3D printers, too. Those may not be so far away, since the architectural types use a wide variety of materials already.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
