If they can make the technology faster I think it will have a huge impact. As of right now its too slow and I think most people do not have the patience to wait for what they would like to make with maybe the exception of a single small part. The other side is that you would need to have a "blueprint" of the object you're attempting to make and if you can't find it will have to create it. Now days you should be able to find just about any part you'd want to make so the speed I believe is the bottle neck at this time. I'm sure it will get faster in time but I don't see that happening as soon as one would hope for.
