In the second video, Blade project lead Brad Balzer goes into detail about how, why, and where they use 3-D printing, and explains the modular nature of their car chassis design. He says they don't need to change many parts to go from ultra-sports car to pickup truck. He also says that while Divergent Microfactories is working on cars right now, their manufacturing system can be applied to many different industries. Indeed, their long-range goal is to help people build microfactories making many different kinds of products faster, more flexibly, and for less money than it takes to make similar manufactured items today.
Note: The transcript covers both videos and has a little 'bonus' material in it, too.
Elon Musk has posted a note on the company's Twitter channel: "Falcon 9 experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data."
Mechanical engineering students at the university built a functioning 1:24 scale model of the Hyperloop, a "fourth mode of transportation" that sends pods through a partially pressurized tube at very high speeds, as part of a senior design project. It was designed to test some of the key components of Musk's design, which was outlined in a much-read, open source whitepaper (PDF) published in August of 2013. That said, there are several key differences, which keep this from truly being a proof-of-concept as to whether or not the Hyperloop will ultimately work.
