Three-dimensional printing is the process of producing three-dimensional solid objects from a digitally prepared three-dimensional file (CAD drawings). The machines that perform these operations are called three-dimensional printers. A three-dimensional printer is a machine that converts computer data into real handheld objects. These machines can produce parts with complex geometry that cannot be produced using traditional manufacturing methods. In order to perform the three-dimensional printing process, computer data is first created in three-dimensional design programs or with the help of three-dimensional scanning systems of the part or parts to be manufactured. The part whose model is created is usually saved as an STL file and transferred to the three-dimensional printer control program. The model is sliced in three-dimensional printer control program, divided into layers and a “G code” file is created. Then, the printing process is carried out by transferring the “G code” file to the 3D printer with the help of a memory card or directly with a computer connection. In the three-dimensional printing process, the object is created by laying on top of each other in layers. Different methods can be used to create these layers. These are methods such as plastic melting, laser sintering, and stereolithography.
Three-dimensional printer technologies accelerate the solutions to such problems by providing anticipation of the problems that may occur during the design and development processes of a new product. Prototypes of all designs drawn in digital environment must be prepared and passed through the necessary tests before starting mass production. The process of prototyping with traditional methods includes both costly and time-consuming activities. However, thanks to three-dimensional printers, desired prototypes can be produced within hours. These prototypes can be easily examined and tested both visually and in terms of functioning. As a result of the evaluations, the design can be changed and the prototype of the re-made design can be produced and examined. This allows us to obtain faster testable prototypes at less cost.
