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?
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
