3-Dimensional Printing By: Kloe Burris Stalagmites and stalactites are naturally formed layer by layer over thousands of years due to dripping water that deposits minerals. By taking this principle, speeding it up, and following an intricate plan, the technology of 3-dimensional printing was formed. The vast field of 3-D printing has several different techniques that are used to create its products, and it has numerous applications to fields such as architecture, transportation, and medicine. Even though it is a relatively new technology, it is slowly taking the world by storm. (“How 3-D Printing Works”) One of the biggest divisions of 3-D printing, bioprinting, is redefining the field of medicine in various ways. Although 3-D printing has yet to be perfected, its ability to apply to all means of manufacturing will allow it to be the main means of production in the near future. (“5 Most Promising Uses of 3-D Printing in Medicine”) 3-D printing is a type of manufacturing technology known as additive manufacturing. Additive manufacturing is the general term for the means of creating an object by adding to the object layer by layer. It is not to be confused with another manufacturing process called computer numerical controlled machining, which creates an object using a subtractive method by removing pieces of an existing object. (“The History of 3-D Printing”, redorbit.com) While there are several different approaches to creating a 3-D object by additive manufacturing, the two most common are rapid prototyping and binder printing. Rapid prototyping was the earliest use of additive manufacturing used during the early 1980’s. It begins with a computer software used to create a design for the 3-D printer to follow. The 3-D printer then used one of numerous substances, such as waxes, inks, or powders, to create the prototype that was used in an industry to
