I hear it frequently when I speak about 3D Printing “Shaan I don’t have a 3D printer”, but they were not aware there are many printing services available locally and on the web. I think that is the business model 3D printing will be for awhile where the design shops and ultra hobbyists may have a 3D printer, but others designing in 3D can still pay for someone else to create the 3D print for them. I don’t think in the near future every home will have a 3D printer, but I believe they will all have access to one. We are starting to see companies like Staples dabbling in a local 3D print services but I want to see a day where the manufacturers of consumer goods provide free or a for a small fee replacement parts or custom modifications that you can purchase online and then pickup at your local FedEx Kinkos which are located about everywhere. That would save time, energy, warehousing, transportation costs and be better for the environment.
