Hacking into 3D Printers

Now a days, new 3D printers seem to be rolling out daily or at least the trends at the crowdsourcing sites indicate so. But how many of these campaigns will finally release a product in the market and will deliver to the mark at the claims made in these campaigns.
May be more than half, but with the expiry of lot important patents in the coming year this trend is going to go up on the rise with more new jargon and technologies being used in their crowdsourcing videos. The promise will be of 10x faster and 50x better technology.
Thus, we have decided to decipher these technologies for you and are going to post each week on a new 3D printing technology, with all what one needs to know to start a crowdsourcing campaign of his own or to decide whether to invest in the technology displayed in such campaigns.
Let us know the technology you want to be hacked in the comments

Imperial March played on a 3D printer

You would have probably seen such You tube videos where old technology is given a second life as a musical instrument. From disk drives to dot matrix printers, there have all been hacked into a musical instrument and the first thing they are made to play is the imperial march from Star Wars.
But, even though being a fairly young technology, 3D printers have also been  made to play the imperial march by syncing its three servo motors to produce the tune.
