3D printing is the process of making three-dimensional physical objects from a digital file. With the help of the 3D printing it is possible to print toys, accessories, sports shoes, weapons, cars and etc. In fact, 3D printing is not a new technology. Its history began about 30 years ago in the United States, when the process of creating volumetric objects from photopolymerizable composite materials was invented. This technology was called stereolithography. Later, the formation of three-dimensional models from various materials was studied, other methods of 3D printing appeared, mainly used in industry and highly specialized production and all of this was called prototyping.

Some areas of application:

• In healthcare - the application of 3D printers in healthcare helps to save lives. Such printers can create an exact replica of a person's skeleton to ensure a successful operation. 3D printing is more widely used in the field of prosthetics and dentistry. Medical three-dimensional models can be made from a variety of materials, including living cells

• In jewelry - It is known that the most time-consuming and capital-intensive procedure in jewelry production is the creation of molds. With the advent of 3D printers, jewelers have the opportunity to quickly increase the molds of jewelry models that were previously made in a special program

• In textiles - 3D technology printers gradually began to be used in the field of clothing production, first of all fashion mannequins were created. Later, with the help of 3D printing technology, a part of the clothing was made using several different materials
