3D-press or "additive manufacturing" - the process of creating three-dimensional solid object practically any geometric shape is based on the digital model. 3D-press is based on the concept of building an object sequentially applied layers, which of mapping the contours of the model. In other words - 3D-printing is the technology that allows you to create the physical (real) objects from 3D computer models. It means that the printer itself already makes it possible to print the finished part - a full-fledged object.
But 3D-models created with 3D-printers are created by hand or computer graphic design at the expense of 3D-scanning. To make it clear - manual modeling remind a sculpture and 3D-scanning - is the automatic collection and analysis of real data object, namely the shape, color and other characteristics, with subsequent conversion to a digital three-dimensional model. Here it is necessary to consider and value of 3D-printora. Have 3D-printers are called computer-controlled machines, builds creating the building parts with additive manner.
History of 3d printing technology.
Although 3D-printing technology appeared in the 80s of the last century, the founder of which is Charles Hull, but the wide commercial distribution of 3D-printers have received only at the beginning of the 2010s.
The usage of 3D-printing:
3D-press used for prototyping and distributed production in architecture, construction, industrial design, automotive, aerospace, military, industrial, engineering and medical fields, bioengineering (to create artificial tissues), the production of fashionable clothes and shoes, jewelry, education, geographic information systems, food industry and many other fields.
Let's look at the usage of 3D-printing technology.
Industrial applications or rapid prototyping
Industrial 3D-printers are used for rapid prototyping and research. Generally, it is quite bulky plant using powdered metals, mixtures of sand, plastics and paper. Such devices are often used by universities and commercial companies. In conditions of successful usage of 3D-printing there occur such a notion as additive manufacturing.
Additive manufacturing means the construction of objects required by the adding the necessary material, instead of removing an extra one as in the case of subtractive methods. It means that the term "additive manufacturing" refers to technology creating objects by depositing successive layers of material.
Mass production - it is primarily domestic, and recreational usage
3D-printers are already used to print working mechanical clock gears for woodworking machinery, jewelry, handbags, clothes and so on. The best example of the massive use of 3D-printing is a 3D-BIOPECHAT used in amateur veterinary and zoology. So in 2013 printed prosthesis allowed to raise duck, and nothing threatens any more to a sea turtle life, because it was injured with a boat propeller and lost her beak.
Scientists were able to make up the missing important organ in the shortest time and return to the life the turtle. 3D-press implants and medicines also highly spread in everyday life. More realistic 3D-printing used in medicine is the manufacture of tablets. Scientists believe that the biggest benefit from the usage of this new technology will get children: a three-dimensional printing will allow to create drugs, exactly following the required dosage.
Influence of 3D-printing
Additive manufacturing requires from the production companies the flexibility and continuous improvement of available technologies to maintain competitiveness. On the one hand, 3D-printing offers constantly growing opportunities, and on the other - many companies are already considering the market effects of 3D-printing. Since for 3D-printing devices have become public available, three-dimensional printers are used for rapid prototyping, that allow reducing development time for new designs.
