Here we go ... Photonic printer

[Gingerbread Demon]

Well that's what I am gonna call this. Congratulations to the MIT people and the creator of this device because we really are pushing technology towards a star trek like level, well not quite but hey manipulating photons to make objects.

The high-tech wizardry of integrated photonics

MIT graduate student Sabrina Corsetti is exploring the cutting edge of integrated photonics, which involves building computer chips that route light instead of electricity. Her projects have included a chip-sized 3D printer and miniaturized optical systems for quantum computing.

I like the slant both articles place on the same story.

Looks like we have a carving beam too

Electron beam method enables precise nanoscale carving and building of copper structures

Creating complex structures at the tiniest scales has long been a challenge for engineers. But new research from Georgia Tech shows how electron beams, already widely used in imaging and fabrication, can also be used as ultra-precise tools to both carve and build structures out of materials like...
