Makerbot Thing-o-Matic #3382
This year I got one of the best Christmas presents ever. It's called a Thing-o-Matic and it's made by a company called Makerbot Industries and what the Thing-o-Matic does is it creates three dimensional objects out of plastic. You give it a file, hit print, and you end up with a thing.
As you can imagine these types of machines are complicated and very expensive. The cheapest one I know of other then the Thing-o-Matic starts at $25,000 which is a bit out of my price range but Makerbot Industries is all about open source and low budget so what you get when you order a Thing-o-Matic is a box of parts that you get the pleasure building yourself.
I spent about 15 hours putting my Makerbot together over a two week time frame and here's a time lapse video that I made of the whole process.
