The other day I was asking myself why 3D printing (from a technical point of view)isn't already a mainstream technology. What is preventing it from booming? What is the problem with the printers sold by Printrbot or Makerbot?
I know the obvious answer is because people don't feel the need for it, but if the technology was marketed properly I am pretty sure its popularity would rocket (simple example: you are missing knife and forks for a dinner you are hosting if you had a 3d printer you print them and have them overnight).
Until now I know that software was also a problem, CAD isn't very user friendly however companies such as Shapeways and 3-Sweep are really pushing towards eliminating the expertise barrier.
This is what I think and was wondering what you guys had to say about this?
