A 3D printer is a device that is capable of outputting three-dimensional data. In other words, such a printer is capable of creating three-dimensional shapes. Everyone is familiar with a regular printer that can print text or pictures. The principle of operation of a three-dimensional printer is similar to the usual, but 3D printers create three-dimensional objects specified in the program. 3D printing technology is based on sequential layering. For printing, plastic is used that melts in the print head. After applying the layers, the plastic hardens and hardens.

The main advantage of such printing in comparison with traditional methods of creating the desired models is the high printing speed, ease of manufacturing figures and their low cost. In other words, it can take several weeks or even a month to create a specific object manually, while 3D printers do the same job in hours, and sometimes even minutes. As a result of manual work, the cost of manufactured products is greatly increasing, since a lot of time has been spent. At the same time, three-dimensional printers have only one consumable - plastic, which has a low cost.
