One thing I know that is being talked about a lot in the industry is clothing. We do not have the technology yet, but someday you will be able to take your measurements and print out your wardrobe and it will fit your body exactly.
Lots of object that you have around the house will be able to be printed out. Want a jigsaw puzzle for your kid? You no longer have to go to the store, just print it out. Need a new toothbrush? Print it out. Time for a new silverware draw? How about a picture frame? Need a set of measuring spoons or cups or even plates or drinking glasses?
The possibilities will only be limited by imagination.
