How long until we have replicators?

Some interesting things going on in the technology world. I really like the fact that these things are becoming more accessible. Check out this really interesting looking Kickstarter:

The part that makes me wonder is this: how long until the companies that manufacture these plastic parts start to apply pressure against this trend?
