- plastic thread or other printer ink
If in the past century, the mere thought of a possible print clothes or things seemed than-That of science fiction, but now it is a reality.Experts predict the rapid spread of 3D printers among many people in the coming years, which will certainly provoke a real revolution in the field of trade.This is due to the fact that people no longer will have to acquire, for example, a sweater in any regular store, you just stock up on a set of various fabrics and printed at this thing with the help of 3-d printer.
Active introduction of 3D-printers in a person's life will entail not only a change in the field of trade, but also to change the usual understanding of the processes of restoration and repair of any items.For example, with the appropriate materials may recreate any item, such as the back panel of the smartphone.3D-printer will also be a great help for many designers: with its help you can quickly print a layout,
basis of any printed items are a few types of plastic, as well as several additional components in modern times is not so widespread (paper composition, starch, gypsum and even chocolate).Externally any 3D-printer resembles most usual printer, which further has a limited space of the layered printing of the final product.The device is built a certain amount of metal rails, which are coupled with the extruder to print or laser.The latter widely distributed of 3D-printers are not used, but it is indispensable in the manufacture of complex shapes, details and fragments mechanisms.
printing principle is based on the use of a special type of plastic, which melts at relatively low temperatures, which reach without damage to the environment may be small in size printer.In a special opening in the device housing, charging coil with a plastic thread that is fed to the extruder.In turn, the extruder processes the raw materials into a homogeneous mass, which is applied to the nozzle.Nozzle for the surface draws special detail sketch each pixel, and plastic for a small amount of time at room temperature solidifies in a certain form.There are no special conditions for work is not required, all you need - a large supply of plastic thread (on average, a month of active work enough 1 kg).
3D-printing is not limited to the use of plastic thread, allowing you to create certain things, for example, made of metal with the help of EBM technology.The printer that uses this technology, print objects using electron beam melting;wherein the term "metal seal" is not applicable to this method, since the material is a metal complex compound and clay.Metal clay, actually serves to ink of 3D-printers, the scientists obtained when combined organic glue, as well as metal chips, and water in a certain proportion.Print bottom line is metal clay is heated to such a state, in which the adhesive and the water will evaporate, and the metal literally srastetsya in a monolithic connection.
actively develops and is an area of 3D-printing, which uses as a base material photopolymer resins which are converted into a real object through exposure to specific DLP-projector.Printers working on this technology, using the relatively new on the market light ink processing technology.The principle of operation is quite simple: by acting in a certain way in the photopolymer resin final product is almost cut out of ink.The relatively recent appearance on the market of this technology significantly even an ordinary user: all printers rather cumbersome, but experts about their future is quite optimistic and predict the imminent acquisition of compact gadgets.
But the most promising area of 3D-printing according to many estimates of scientists - this is where the printer as the ink used high-performance thermoplastic that provides not only high thermal, but also chemical and mechanical strength of the final product.Printing using thermoplastics favorably with most compact printer, printing a total purity, and ease of use of the devices themselves.This type of printing even allows the creation of a home much more complex structure than previous described, due to not using the same material, but also additional (or more).Thermoplastics typically also charged into the cell specific printer, which later served in their molten state on several axes.
This 3D-printer is printing in layers that can be compared in part to the construction of any houses from LEGO bricks.However, the factor relating to the merits of the technology, some can be perceived very negatively: the fact that the support materials have to be separated by physical, because the printer yourself this procedure is not able to exercise.The use of this type of 3D-printers and has established itself among the youth and the adult generation: for example, at the TED conference were examples of print for plastic shoes and clothing.
