In the recent decades of development of manufacturing and production engineering, 3D printing technology has emerged as one of the most promising area for research and development. With the availability of flexible and user friendly manufacturing and interfacing system, the 3D printing technology has attracted a lot of researchers form keen aspects of their field. Medical Engineering is the branch of science that deal with the application of technological aspects in solving medical problems. With the merger in these two vast fields a lot of problems has been answered and the development of new things is on their verge of initiation. In the recent decade both the engineers and medical researchers have worked on integration of technologies to solve the medical problems globally. In the scenario, a lot of technology like 3D printed Heart, Kidneys, etc., & physical implants like teeth’s, bones and medical support. In this report, I have tried to acknowledge the work done in the field with their importance in the ever changing scenario of the world.

4. Stereolithography
• Stereolithography is a form of 3-D printing technology used
for creating models, prototypes, patterns, and production
parts in a layer by layer fashion using photo polymerization, a
process by which light causes chains of molecules to link
together, forming polymers.
• Charles W. Hull in 1986 was the first to use the technique to
create a 3D Figure.

10. Uses
Medical
Modeling
Used to create various part of body for study purpose, or
for replacing damaged ones.
Stereo lithographic models are used as an aid to diagnosis,
preoperative planning and implant design and manufacture.
Prototyping It is used to create testing models, because of low cost and
less time consumption

It is used for:
• Preparing new Doctors for
surgery
• To understand patents internal
structure after causality
• To prepare operation strategy
• To reduce possible chances of
risk in an operation
