I guess soon we'll all be making our own custom working cars.

All by using something called a 3d printer...

This technology looks superb but is it affordable for the average man and hopefully
I don't have to be a trigonometry expert or something? I think it's similar to using visual patterns in your average scheduling software but you upload the visuals to a printer instead of adding it to the code.

Happen to come across a few of these blueprint files (Guess they are required for this printing machine) my self as well.

Like this Roof Wire Canal.

Did anyone dabble into this yet? Love to hear some real life experiences.
