Marketplace Tech Report had a piece on 3D printing this morning. I came away with two thoughts:
1: I MUST see photos of the bicycle made from 3D printed parts that Jonathan Zittrain mentions in the interview. (So far, no dice. If you find anything, let me know.)
2: "Holy Cats! I've never watched a 3D printer work!" Luckily, YouTube came through for me. Big time. I chose this video to post because of the nifty song that goes with it, but there's lots more 3D printer videos available—including some that feature DIY printers. Follow the link, be awed, kill lots of time.
