I like to be realistic about these things and so I often miss the boat when it comes to the future of technology. But in this case I think the sky is the limit. The technology has improved so quickly and the prices have dropped so dramatically that it is completely within reason that many homes will have this technology in the next 5-10 years. The software is getting better and the ability to scan and print in a single machine makes it possible for novices to make simple objects with little knowledge. I think further advancement in materials and technology and products for printing that we will see a true consumer factory at home possible.
