Deakin researchers develop concrete solution for recycled glass | Deakin
some types of colored glass aren't recycled due to the difficulty in cleaning it up to clear again, so being able to use it elsewhere is a plus as an alternative to high grade sand. But this is polymer resin based concrete (substituting cement) so that's a different problem...

Titomic - Industrial Scale Additive Manufacturing, 3D Printing, Titanium, Innovative, Melbourne, Australia
Using supersonic metal particle sprays to get get powder fusion via kinetic impact, not too far from older metal cold spraying techniques. Not using bulk heating so less likely to have warped parts from SLS/SLM methods. Doing aerospace grade titanium, with an ITAR compliance area as well?

KIT - KIT - Media - Press Releases - PI 2015 - Crack it! Energy from a Fossil Fuel without carbon di-oxide
Hrm, I suppose if you had a handy methane source and a heat source (1200 C?!?), this is interesting (GenIV nuclear reactor maybe), but probably the more interesting aspect is the pure carbon powder byproduct, suitable for making carbon fiber and similar. I suppose if you wanted to make graphene, using natural gas from town as both an energy source and a carbon source for production might be a good match...

European Space Agency Awards €500k for New Cold Spray 3D Printing Technology
Interesting, using cold helium to increase the speed of sound of the neutral carrier gas for a metal powder spray, so it uses impact bonding rather than some kind of laser heating.

DDM Systems LAMP
New 3D printer based investment casting technique. Cuts out 7 of 12 steps, possibly a faster alternative to 3D lost wax process. UV laser builds up powdered ceramic resin for cores and molds. Aiming for single crystal directionally solidified equiaxial nickel superalloy hollow turbine blade production.

LASERTEC 65 Shape - A LASERTEC Milling Machine by DMG MORI
Interesting, Basically your typical 5-axis milling machine, but it seems to swap heads then uses a fiber laser to do blown powder direct metal laser sintering on the milled surface to add specific textures. Not quite a free form 5 axis 3D printer head system, but close.

Research of Graphene-reinforced Aluminum Matrix Nanocomposites
Seems like if the powder grind/mix is well done, you get pretty awesome graphene nanoflake reinforced aluminum composites. Apparently they got over a previous issue, where CNT's in an aluminum matrix turned into aluminum carbide, lowering materials properties.
