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.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
