Wearable LED lamp belt is kinda nice, not sure you really need the other safety features though...

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.

Interesting LED lamp that uses saltwater and sacrificial electrodes to generate power. A sacrificial magnesium rod works with salt water (such as ocean water) to create current to power the LED light. Fill the lamp once with seawater to get 8 hours of light apparently (need to swap salt water at that point due to chemistry). The sacrificial rod is good for 120 hours of use, though you probably should flush the thing with freshwater and dry it out for storage.

A nice little system using LED lighting to also transmit data, combined with a custom small form factor retroreflector/receiver (not much bigger than existing IRda sensors). They are also doing PLC and DC PLC work, so that the overhead lamp assembly contains not only the LED and transmitter encoding circuits, but also a PLC modem for transmitting data over the power supply circuit so you can retrofit into exisitng lighting systems without running new data cables.

Uses a halogen lamp rather than a laser for sintering/heating the material, but apparently suffers from an overhang support substrate problem (not that big a deal)?
