I watched a great episode of NCIS: Los Angeles that was totally centered on 3D!  In this episode a crime was committed in a dangerous place so the team decided to totally recreate the crime scene.  A team first infiltrated the site to for a laser scan and then it was printed full size to allow for a complete crime scene investigation.  So I can’t imagine this being an everyday police application, but it would allow CSI’s to recreate a crime scene anytime they wanted or even create exhibits for jurors.  Good to see 3D printing getting some positive Hollywood love rather than another plot based on an untraceable 3D printed gun used in a murder.
