So it looks like they’re using a photo booth so they’re using a 123D Catch like software to create the 3D models then they’re using a powder sintering printer so they can print in full color, which is going to be the costliest and slowest part of the whole process. To be clear I don’t think this isn’t printed as you wait. This will be more of a “Pay your $100 and we’ll ship it to you when it’s done.”
And rumors are this is a $100 service and for a limited time only. I guess being this on the cutting edge isn’t as profitable as Disney hoped.
