• A new (or enhanced) 3D data format would have to be designed to accommodate for the new food and cooking oriented features - heat sequences, wait times, etc.
  
• An ecosystem of recipe repositories would erupt, complete with rating systems, images and taste tests. And then: Pirate Food!
• A highly competitive industry providing raw food materials would emerge, likely starting from home food designers, but moving up to industrial scale operations, too
• Grocery store shelves would be stocked with Tassimo-like food factory cartridges, perhaps organized into "meal kits" containing all the ingredients and recipe files for themed events. We'd probably like the bean burrito package
  
• iPhone apps would permit selection of meals remotely, allowing one to eat immediately after arriving home

New developments are afoot in color sheen printing. Recently researchers at  Adobe Systems and Dartmouth college managed to create an inkjet printer capable of producing reflective surfaces in a variety of colors.

Their color thermal printer is "versatile enough to print many metallic inks and foils as well as standard inks." 

One issue they've encountered is a way to capture reflectivity information from objects, which would then be fed back into the printer for reproduction. How do you easily measure and capture reflectivity information?

But here's the part that interested us:

The goal is to combine the technique with 3D printing to create 3D objects that look more realistic

ProFORMA uses a fixed video camera to allow on-line reconstruction of objects held in a user's hand. Partial models are generated very quickly and displayed instantly, allowing the user to plan how to manipulate the object's pose in order to generate additional views for reconstruction. We demonstrate how augmented reality can be used to assist the user in view planning, guiding the user to collect new keyframes from desirable views in order to complete and refine the model.

• The number of applications of 3D printing continues to increase. We've seen medical, artistic, manufacturing and other uses appear simply due to the creativity of makers worldwide, and every time a new use appears, a new set of folks are aware of the potential
• 3D printing capabilities continue to expand. We've recently seen printing in metal, multiple colors, more robust materials and improved resolution and build times. These will only attract more uses
• Costs of 3D printing continue to decrease. We have not yet hit the magic "it's cheap and easy enough for Mom to have one at home" level yet, but that's clearly going to happen within a few years
• Open source / hackers are now fully on the problem and are building radically new solutions to problems in the space - and at very low cost

A team of engineers and artists working at the University of Washington's Solheim Rapid Manufacturing Laboratory has developed a way to create glass objects using a conventional 3-D printer. The technique allows a new material to be used in such devices.
