Futurama season 7 episode 17
Episode title: Forty Percent Leadbelly
Bender meets his hero, a famous folksinger who has been in jail 30 times, and wants to duplicate his success. This means duplicating his guitar too, which he tries to steal from a maximum-security prison, but fails, so instead resorts to 3D-printing technology to duplicate the guitar — again resulting in horrible consequences.
