Although 3D printing has various functions in a variety of industries, but in the medical device industry 3D printed medical devices have four main applications. Firstly, 3D printed medical devices are used for bio-printing tissues and organoids. Secondly, 3D printed medical devices are also used for surgery preparation by creating patient-specific organ replicas than can be practiced upon by the surgeons before performing complicated operations. Thirdly, 3D printed medical devices are used for producing surgical instruments like forceps, hemostats, scalpel handles, clams, etc. Fourthly, 3D printed medical devices enable formulating customized prosthetics.
