A 3D printer is a limited type of industrial mechanism capable of applying an additive method associated with computer management. 3D printing is considered as desktop manufacturing or additive manufacturing, it is a prototyping method in which a real object is formed by a 3D style. The digital 3D model is saved in STL format then sent to a 3D printer. The 3D printer then prints the appearance layer by layer and forms a real object. Not like ordinary printers. On a 3D printer the object is written in 3 dimensions. A 3D model is built layer by layer. Therefore the whole process is called rapid prototyping or 3D printing. One of the most important applications of 3D printing is in the medical sector. With 3D printing, surgeons will make models of components of the patient's body on which he is to be operated on. 3D printing makes it possible to create a location from scratch in just a few hours. It allows designers and developers to travel from flat screen to exactly half. Today, almost everything, from components to toys, is designed with the help of 3D printers. 3D printing is also used for jewelry and art, design, fashion, art, interior design and style. 3D printers have exploded in quality with the promise of reinventing everything from manufacturing to entrepreneurship. While 3D printing has some detractors and people at the UN agency mean it won't live up to expectations, I believe 3D printing can truly reinvent the way we tend to model and build things. Ultimately, I feel it will greatly improve life in third world countries by allowing everyone to improve their lives. In a world with the gift of the 3D printer at home, in the office, on the high street or on the scales... in the middle of paper. .....several implications for the future of medicine with the recent spike in 3D printing advances. Not only will it help current surgeons move organs and other components effectively, but it will also help medical students develop their surgical skills. Now, medical companies are poised to produce “ultra-realistic” 3D written organs and alternative components that almost completely mimic the feel and structure of real body components. The plastic used in these components is created using many textures, shapes, colors, and degrees of durability. The relative ease of making these “parts” makes following faster, cheaper, and globally accessible. Whether or not it involves surgery, tumor removal, or knee replacement, the existence of such materials exponentially expands the frontiers of medical analysis.
