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.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
