I don't believe this is shaking up anything. What this person is doing(I know personally the guy, I was born in Spain) 2D presentations(plotters) has been done by cookers manually for decades.

IMHO 3d printers are going to be very important in the future,but not in their current form.

I volunteer teaching kids 3d printing and engineering not because the present but because of the evolution of it in 10 or 15 years.

Like it was essential to me to have an assembler or compiler when I was young in order to own a computer company or control machines as an adult, being raised with 3d printing is going to be essential for owning the robotics and technology space of the future(DNA manipulation).
