3D printing is a term for various production techniques in which a product is built up layer by layer. A 3D printer adds material to an object until the desired shape is reached. This is a form of additive manufacturing which is an excellent alternative to sub-additive manufacturing. A great benefit of 3D printing is the fact that it generates less waste of material. This production technique is becoming more and more popular around the world, and thus, now you can buy a 3D printer without spending a fortune. The capabilities of such devices are diverse, and a wide variety of materials can be used for this kind of production, including plaster, gold, bioplastic, ceramic, photopolymer, wood, titanium, ABS, sand, PLA, polyester and epoxy. 3D printing is also used for the production of functional parts. It makes it possible to produce a real object; however, it is necessary to draw it on a screen using a computer-aided design (CAD) tool first. Then the 3D file is sent to a specific software which cuts it in slices and sends to the printer. Eventually, by using deposits or other material, the 3D printer creates layer by layer to get the final product.
