3D printing is utilized for the development of novel surgical cutting and drill guides, prostheses as well as the fabrication of patient-specific copies of bones, organs, and blood arteries. Recent advancements in 3D printing in healthcare have resulted to lighter, stronger and safer goods, shorter lead times and cheaper prices. 3D printing has been utilized in the health industry to manufacture both basic and sophisticated prostheses as well as surgical implants. Apart from this, 3D printing may be utilized to create personalized prosthetic limbs that are appropriate to a particular patient. 3D printing is a relatively new, quickly growing technique of production that finds many uses in health- care, automotive, aerospace and military sectors and in many other fields. In this overview, applications in medicine that are changing the way operations are carried out, affecting prosthesis and implant industries as well as dentistry will be discussed. The relatively new subject of bio-printing that is printing with cells will also be briefly addressed.
