Microsoft announced earlier that Windows 8.1 includes native support for 3D printers, now Microsoft shared additional details on this new project during this week's SIGGRAPH 2013 conference.

"The age of 3D printing, when every object so created can be personalized, will increase the need for tags to keep track of everything. Happily, the same 3D printing process used to produce an object can simultaneously generate an internal, invisible tag," say scientists at Carnegie Mellon University and Microsoft Research.

These internal tags, called InfraStructs, can be read with an imaging system using terahertz (THz) radiation, which can safely penetrate many common materials. The idea is simple, 3D printed objects could have embedded coded tags that are placed within these objects.

InfraStructs can be made with the same layer-by-layer process used for producing the object. The code could be anything from serial numbers to images, or even simple programs. A terahertz scanning device can read and decode the information on those tags.

THz radiation falls between microwaves and infrared light on the electromagnetic spectrum. It can penetrate many common plastics, papers and textiles but, unlike X-rays, does not harm biological tissues.

The tags themselves come at no extra cost, said Karl Willis, a recent Ph.D. graduate in computational design at Carnegie Mellon. But THz imaging, still in its infancy, can be pricey.

As this imaging technology matures and becomes more affordable, however, InfraStructs could be used for a number of applications beyond keeping track of inventory or making point-of-sale transactions.

For instance, they could help mobile robots recognize or differentiate between things. They might encode information into custom accessories used in game systems. Or, they might enable new tabletop computing scenarios in which objects can be sensed regardless of whether they are stacked, buried or inserted inside other objects.

What this does is pretty much demand you move to open source if you do not want tracked. If you give a crap about your privacy ---even of the things you make in your own home - you will need to use only open source software.

typical Microsoft, trying to control and regulate everything...

THz radiation can be produced with fs lasers which are many thousands of dollars. RFID tags are pennies. It would take a major breakthrough or just the right kind of application to make this economical.

Sorry to be blatant & blunt, but, Fuck Off! YOUR NOT EMBEDDING TRACKING IN MY POSSESSIONS!!!!
