“The screw will turn very slowly in the manufacturing industry until everyone is using 3D printing in one way or another. As technology improves and the costs come down, there will likely be little reason for anyone to avoid the 3D printer, and more consumers will have their own 3D printers in their homes. The outcome of the 3D printing revolution may not be known for years, but it has certainly started. Only time will tell how it will all play out.”
