If you haven't seen it, you should watch "Print the Legend", a documentary about a few 3D printer startups like MakerBot, FormLabs, etc. It's on Netflix streaming: https://www.netflix.com/watch/80005444
Such a good documentary. I feel it is a great behind the scenes on the stresses of startups in general.
I actually wrote this comment 2 days ago. It's interesting that HN corrects this to "2 hours ago" to fit the post timeline, which was also originally 2 days ago. Note, the original post didn't make it to the front page unlike now. Weird stuff.
When dang reposts a story everything gets updated to the new time.
