A printer It is a device that allows you to print: print or mark a subject with graphic characters or letters. The most popular printers are those that connect to a computer (a computer) and that are used for printing on paper a digital document, such as a text or a photograph.
3D , meanwhile, refers to what three-dimensional . An element is three-dimensional when it has three dimensions (such as depth, height and width, to name the most frequent case).
With these ideas clear, we can focus on the definition of 3D printer . This is called the machine that can produce a volumetric piece starting from a three-dimensional design . These designs, in turn, can be developed with a computer or obtained through a 3D scanner .
3D printers are often used today to manufacture various types of components and parts. One of its most common uses is linked to the production from medical prostheses thanks to the facility to adapt the elements to the particular characteristics of each individual.
According to their technology , 3D printers appeal to different processes for printing. Among them stands out the one that is carried out by accumulating layers of dust of various metals, which are fused together with a laser. It can also be printed by compacting the dust strata or through polymer injection.
Once the Print is completed, the user extracts the part created with the 3D printer. The result is a homogeneous product , without traces of the layers that composed it in the preceding stages.
