3D Printer is very popular now a days. Previously it was used in industries only but now it is very common that most of the people used it at home. In this article we explained all about the 3D Printing & 3D Printers. Also we have recommended some best 3D Printers which you can purchase for your office or home.
What is 3D Printing?
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. The term "3D printing" can refer to a variety of processes in which material is deposited, joined or solidified under computer control to create a three-dimensional object, with material being added together (such as plastics, liquids or powder grains being fused together), typically layer by layer.
In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. As of 2019, the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term additive manufacturing can be used synonymously with 3D printing. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise impossible to construct by hand, including hollow parts or parts with internal truss structures to reduce weight. Fused deposition modeling (FDM), which uses a continuous filament of a thermoplastic material, is the most common 3D printing process in use as of 2021.
How 3D Printer Works?
CAD model is input for the 3D printer and turns it into a physical three dimensional object by adding material layer by layer. 3D printer adds filament to the building object layer by layer during 3D printing process. In this way of manufacturing the object arises from scratch. Printing material (filament) is added to the object being created in small portions. The first thin layer of the filament is placed on a plain work table surface. After that it is added the next layer above the first one. So the intended object is growing up layer by layer with the help of a 3D printer.
Depending on the type of printer and size of the object, a print takes several hours to complete. The printed object often requires post-processing (like sanding, lacquer, paint, or other types of conventional finishing touches) to achieve the optimal surface finish, which takes additional time and manual effort.
Different types of 3D printer employ a different technology that processes different materials in different ways. Perhaps the most basic limitation of 3D Printing, in terms of materials and applications, is that there is no one-size-fits-all solution.
