3D implants provide 3D printed on-demand solutions in the field of healthcare, prosthetics and surgical aids. 3D printed biodegradable porous screws with tunable dimensions for bone injuries were developed for better tissue-integration and biocompatibility compared to commercially available non-degradable metallic screws. 3D implants have developed personalized breathable, washable lightweight orthopedic hand casts for fractured arm replacing the conventional plaster cast. This is one of the promising projects where perfect-fit, well-ventilated, easily worn and shower-friendly hand casts customized for patients. 3D implants also offer anatomical models for critical surgery planning that contributes to faster, less traumatic and more precise surgery. Also, 3D Implants developed ventilator splits and flow limiters using 3D printing process to meet the increasing ventilator demand during the emergency COVID19 situations. Face masks and face shields have also 3D printed during the covid emergency.

PLA based 3D printed 2-way and 4-way splitters for ventilators were designed, developed and tested successfully in TN RGGH(MMC) to address the ventilator shortage in COVID-19 pandemic. 3D splits which are connected to ventilator ports can ventilate four patients at a time. Face masks, gears & shields were 3D printed for personnel in Covid 19 relief work. They also developed AMBU bag based ventilator which can work on both volume and pressure modes.
