3D Printing Allows The Production Of Significantly Smaller Cameras With Medical Uses

Micro-Camera Can Be Injected with a Syringe

German engineers have created a camera no bigger than a grain of salt that could change the future of health imaging—and clandestine surveillance.
Using 3-D printing, researchers from the University of Stuttgart built a three-lens camera, and fit it onto the end of an optical fibre the width of two hairs.
Such technology could be used as minimally-intrusive endoscopes for exploring inside the human body, the engineers reported in the journal Nature Photonics.

"Due to manufacturing limitations, lenses cannot currently be made small enough for key uses in the medical field, said the team, which believe its 3-D printing method may represent "a paradigm shift"."
