Another breakthrough has been made in the world of 3D printing as new tiny cameras have now been developed using this technology that is small enough to be injected into the human body with just a standard syringe.  That is pretty impressive!  These tiny, microscopic cameras are the size of a grain of salt, but they could transform the world of healthcare as we know it.

Produced by a team at the University of Stuttgart, this three-lens camera is another fantastic example of just what we can achieve with the technology around us today.  By using a 3D printer to churn out the lenses, manufacturers will be able to produce them in no time at all and to specific requirements, if need be.


The cameras are so small that they can be printed onto the end of an optic fiber and then inserted into the human body, including the brain, to be used as a camera.  This will allow doctors to have a much better view of the internal organs and is less invasive than a regular endoscope.  The printing technique was developed by using lasers with very short pulses that were focused through a microscope onto a liquid polymer.  Then, when the 3D printing occurs, the lasers harden the polymer as the lens is produced.

As well as being used for groundbreaking medical advances, these tiny little cameras could also be as surveillance devices, or if used in connection with the right sensors they could also be used in the production of self-driving vehicles.  This type of 3D printing will pave the way for further developments in both the technology and health sectors and more innovative will be just around the corner.
