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?
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
