Elizabeth, this was a very interesting article. You noted Redeye would be building a factory for their mass production.
I would hazard to guess most readers realize 3D printing is a relatively slow process (vector pen-plotters come to mind). Is it Redeye's contention that, while the 3D printing process is slow by itself, when making a complete car body 3D printing it is as fast or faster than traditional discrete component + fasteners assembly?
To put it better, is the time and labor it takes to 3D-print a complete car body in one go the same or less than machining all the individual parts and then assembling them with fasteners and adhesives?
If that is the case, then Redeye's eliminating a substantial portion of the assembly line at Ford, GM, and Chrysler. One wonders how the labor unions will react to this use of 3D printing?
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
