I didn't spot this video in the previous contributions.  This technology generates net shape parts that require significant finish machining so it is a bit different.  On the other hand, it works with metals that are used for high load/heat environments.  The sponsor list at the back end ties the work directly to defense/aerospace.

Speaking from direct experience, this is definitely for aerospace applications (and is being used) - its key advantage over many of the other techniques is that is can handle bigger parts.

A new wrinkle in 3D printing where continuous laser polymerization of resin is modulated by inhibiting the reaction with Oxygen.  The result is 100x faster part production.  The company is still in start up phase but is attracting lots of venture capital and may become one of the big players in the field.

Really cool story they 3D print an image of a blind women's unborn child so she can 'feel' what he looks like.

I wonder whether it outperforms a JetCat? Could be Yves Rossy'snext step in increasing his T:W.

By the way, this topic really should be in the Aerospace board.

3-D Printing Holds Huge Promise for AFMC

 —John A. Tirpak9/17/2015

​Additive, or 3-D, printing is one of those technologies with “huge implications” for the Air Force’s ability to affordably sustain its forces, Air Force Materiel Command chief Gen. Ellen Pawlikowski said Tuesday at ASC15. Especially given the fact that so many USAF platforms are old, and for which parts are no longer available, 3-D could be a windfall development, she said. She noted that a B-52 component long out of production—the absence of which would ground the airplane—was digitally mapped by one of her engineers and a usable replacement printed “with a three-day delivery,” she said. Moreover, the component had more than 100 parts, but the printed version was a single part. The ramifications are that whole warehouses of parts could be eliminated, creating spares only when needed. “All you need is to keep the data file,” she said. She pegged the technology right after directed energy, autonomy, and hypersonics as the biggest “game changers” coming in the next decade.

MIT 3D printed glass.  Looks like extruded glass laying rather than 3D printing with a laser heating a bed of powderized glass.  Not sure if this will go anywhere unless they can get the extrusion shape to allow contiguous patterns with no corrugations.
