It suspect there will be a market for Kinkos or someone to get into, but I doubt it will pay Joe Sixpack to have a solid object printer for the first 50 years. Just not enough need, and way too expensive and limited in the materials department.
Still this technology has been demonstrated and machines that "print" solid objects out of plastic exist, and as the available build material list grows and the technology gets cheaper you can expect this to really take off.
