They seemed ignorant, but that is 99.9% of the world when it comes to 3D printing. They are looking at 3d printing the same way the most of the world looks at it. If Bre can't convince them, he won't convince the rest of the world unfortunately. I agree with a lot of what these guys said. Plastic printed stuff just isn't all that feasible. I think we will begin to see more materials in the coming years. Once we can print in metal, that's when I think it will take off. The Mark One's carbon fiber printer is a good step in that direction.
