Background / Introduction:
3 D printing is used in industries to manufacture high precision parts, toys and even buildings now a days. It was natural that the role of 3D printing was going to develop rapidly in medical fields. The 3D printing has been used in medical education, diagnosis and understanding the extent of pathology in human body. The role of 3D printing in orthopaedics is well established. The 3D printed models of pathology can guide the surgeons to plan their surgical approach etc. The patient specific instruments are now commonly used in joint replacement. The 3D printed cutting guides can be used for performing osteotomies etc. 3D printed implants have proven their worth. There is lot of research in tissue printing. The printed skin is already in use.

Patients / Methods:
Pilot study


In addition to printing 3D computer modelling of patient anatomy for planning of complex surgical procedures and implants, the technology can be augmented with virtual reality (VR) to facilitate clinical training at remote locations. With combination of these technologies, it is possible to perform many surgical procedures virtually similar to flight simulation training techniques. The good news is that we are moving forward in our institution on this front. The idea started about 8years ago, it has gone through the usual hurdles. We have now acquired FDA approved Stratasys Medijet JD5 medical printer along with certified medical software for clinical applications This has now given us the capability to print medical devices such anatomical models and surgical guides that are biocompatible and sterilisable hence can be used within operating theatres.

The biomedical department has been the main driver of the project. There is a dedicated space for 3Dprinting in the under-construction Hunter Innovation and living Lab( HILL) (old library area). We will have access along with other specialisations. The printer and whole package come with a software that has provision for integrating with VR technology.. Here we present an introduction and outline of the facility and what has been achieved so far.
