A 3D printer is a computer-aided manufacturing (CAM) device that creates three-dimensional objects.
It also receives digital data, like a traditional printer, on the basis of input from a computer. Whereas instead of printing this output on paper, a 3D printer produces a three-dimensional model that too from the custom material it has.
The technology 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, this technique is completely different from subtractive manufacturing, where a machine either reshapes or removes materials from an existing mold.
Since 3D printers create models from scratch, they are more efficient and generate very little waste as compared to subtractive manufacturing devices.
The process of doing 3D model printing varies greatly for different materials. For example, to make a plastic model, 3D printer heats and fuses layers of plastic together, while this process is called fused deposition modeling (FDM).
Whereas while creating a metallic object, a 3D printer uses direct metal laser sintering (DMLS) technology. In this process, thin layers of metal are formed from metallic powder that to using a high-powered laser.
Where 3D printing had been made since 1980 and they were used exclusively for large-scale industrial purposes only. Whereas in recent times, 3D printers have become much cheaper and are now available only in the consumer market.
As its technology is becoming more widespread, the day is not far when 3D printers
