Industrial 3D printing supplier ExOne's M-FLEX midsized metal printer is three times as fast and has a build volume more than seven times as large as the company's previous midsized machine. (Source: ExOne)
You are correct on the time required to build large parts. ExOne specs a minimum thickness of .1mm(.004") which could yield quite large build times, on the order of 2 hours per inch of thickness. Also, print precision is listed at .06mm(.0025") in the X/Y direction. In a lot of industries that would not be considered high precision so some post build machining might be required. All that being said, this is still exciting technology that is relevent now and will continue to improve in the future
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
