A 3D printer is a computer-aided manufacturing (CAM) device that creates three-dimensional objects.

Like a traditional printer, it receives digital data on the basis of input from a computer . , While the output of the service to print on a paper, create a 3D printer uses a three-dimensional model that’s him Mehjud custom of material.

The technique that 3D printers use is called additive manufacturing . In this technique, to make a physical object , it is added layer by layer, to prepare it until the model is completely complete.

At the same time, it is completely different from subtractive manufacturing , where a machine either reshape or remove materials from an existing mold.

Since 3D printers create models from scratch, they are much more efficient and generate much less waste compared to subtractive manufacturing devices.

The process of doing 3D Model Printing is quite different for different materials. Just as to create a plastic model, the 3D printer heat and fuse the layers of plastic together, while the process is called fused deposition modeling (FDM).

While creating a metallic object, a 3D printer uses direct metal laser sintering (DMLS) technology. In this process, thin layers of metal are made from metallic powder using a high powered laser.

Where 3D printing was made since 1980 and they were used exclusively for large scale industrial purposes. At the same time, 3D printers have become much cheaper and now it is available only in the consumer market.

As its technology is becoming more widespread, the day is not far when 3D printers will become a viable means for people, so that they can easily make all their home products and replacement parts.
