3D printers are printers that can print in x, y, and z-direction. It involves a process of printing a 3D object. 3D Printing, also known as Additive Manufacturing (AM), refers to processes used to synthesize a 3-dimensional object in which successive layers of material are formed under computer control to create an object.
A 3D Printer is a machine, just like a regular Ink Printer. The only difference is that a 3d printer uses Plastic instead of Ink & uses another Axis (Up and Down).
INK PRINTER = X and Y
3D PRINTER = X, Y and Z
A 3D printer prints 3D objects.
For example: Instead of printing a picture of a box, a 3D printer is able to actually produce the box itself.
The main advantage of 3D printers is that the material is all stored in one location. The printer head does all the work in getting the material where it needs to be. Also, because the printer is controlled by mechanical parts & motors they can generally do the job much faster. It is done with greater precision and accuracy than any other process.
