Based from what I see from this video, Soon parents wont be buying toys from the store, they will be printing it. Soon we may never need to buy a new pair of shoes, we will just download patterns that we can 3d print. There are 3d printers for plastic, metal and there are even 3d printers of food. Do you think 3d printers will be attached to many home computers one day? what do you think of this technology?
